ISONIC 3507 is a dual channel version of the ISONIC 3505 instrument. ISONIC 3507 carries the exceptionally innovative
dual channel ultrasonic card with never-saturated-receivers; each of the receivers keeps the linearity over 140 dB dynamic range digitizing the originally received
signals independently on the gain and rectification settings in every firing / receiving cycle. For each channel every single A-Scan or the sequence of A-Scans forming a record stored into
a file may be reproduced then off-line in the form desired by an operator (RF, half- or full wave rectified, FFT) at any gain level over the said 140 dB range. So even in case of
very significant deviation of the pre-inspection gain setting from the required one the observation and evaluation of the recorded data may be performed at the right levels without secondary scanning
The top level ultrasonic performance of ISONIC 3507 channels is achieved thanks to the said never-saturated-receiver and to the versatile firing circuit allowing forming of the
Spike, Unipolar-, or Bipolar Square Wave initial pulse with wide-range-tunable duration and amplitude (up to 400 Vpp). The high stability of the square wave initial pulse
amplitude within entire duration of the positive and negative half-waves, the extremely short boosted rising and falling edges and the automatic adaptive damping allow optimizing of the ultrasonic wave penetration
into various materials characterized either by high or low grain size, sound attenuation, and the like and improving of the signal to noise and the resolution
ISONIC 3507 is a direct successor of ISONIC 2007 instrument. It may be operated as single or dual channel unit. Each single channel carries the functionality as below:
superior performance A-Scan set including the spectrum analyzer for ultrasonic signals
fully featured (data capturing and enhanced postprocessing) standalone TOFD unit
CHIME system
general purpose CB-Scan machine for the performing of:
SRGW (short range guided wave) inspection and imaging also known as SRUT
surface / shear wave inspection and mapping
volume overlay incidence angle / skip corrected high resolution flaw detection B-Scan and Thickness Profile recorder
C-Scan through raster scanning with straight- and angle beam probes either mechanic-free or with use of the mechanized or automatic XY scanner (optional)
In case of dual channel operation the strip-chart forming and recording is provided; the strip chart may comprise:
TOFD (CHIME) strips
Map / PE strips (switchable on- and off-line)
a combination of 2 strips of different type, for example TOFD + Map, Map + PE, etc
100% raw data capturing is provided for all recorded inspections. Whilst in dual channel mode the channels may perform the firing-receiving cycles either at parallel or in sequence
Thanks to the never-saturated-receivers each channel of ISONIC 3507 is featured with the ability of individual gain control for both independent gates over the
range of 140 dB separately from the rest of the A-Scan reproduced at the global instrument gain. This opens a number of new abilities such as:
implementing the pulse echo and back echo attenuation inspections simultaneously with use of the same A-Scan whilst monitoring the back echo amplitude at the
clearly visible level without affecting the sensitivity of the pulse echo inspection
increasing the detectability of subsurface defects for TOFD inspection through shortening the tail of lateral wave signal dynamically
precise materials characterization through the signal spectrum analysis independent on the instrument gain setting
etc

Single Channel A-Scan - Time Domain Signal Presentation
In the ISONIC 3507 the single channel A-Scan mode of operation is used for the various pure A-Scan based inspections and for the calibration purposes prior to the inspections
performed with the data recording through either Line- or Raster- scanning
Each of two identical UDS 3-9 Pulser Reciever modules (channels) carried by ISONIC 3507 is controlled independently and exactly in the same manner as ISONIC 3505 providing
the top level A-Scan ultrasonic flaw detector functionality
Thanks to the ability of generating the spike, the unipolar, and the bipolar square wave initial pulse each channel of ISONIC 3507 is suitable for the resolving of the widest variety of ultrasonic inspection
tasks. The amplitude of the initial pulse is smoothly tunable for all generated shapes – there are 14 possible grades of Firing Level; the maximal grade (14) corresponds to 200 V amplitude of the unipolar
initial pulse / 400 Vpp amplitude of the bipolar initial pulse. The instrument screen movie below taken with no probe connected illustrates the possible shapes of the initial pulse and manipulations related
to the settling of the pulse width and firing level
The signals received from the material may be optimized significantly whilst resolving certain inspection tasks with use of suitable probes - for that purpose
each channel of ISONIC 3507 carries the ability of selecting most suitable shape of the initial pulse and tuning it's width and firing level accordingly; the instrument screen movie below illustrates the influence
of the shape of the initial pulse and the pulse width settings on the echo amplitude, signal-to-noise ratio, etc
There are 10 grades for the active damping of the initial pulse available; varying damping allows shortening of the echoes received from the material without affecting their amplitudes - the instrument screen movie
below illustrates an example of the same

The receiver of each ISONIC 3507's channel keeps the linearity over 140 dB dynamic range and digitizes the actual waveform of the signal independently on the way it is displayed on the screen. These unique
features of the instrument are illustrated by the videos below
The types of the time domain signal presentation. Independently on the time base and DAC and TCG settings it may be toggled between:
RF – not rectified; represents the actual (real) waveform of ultrasonic signals
Full Wave rectified
Half Wave rectified either Positive or Negative
Logarithmic
Thanks to keeping the receiver's linearity over 140 dB dynamic range the signals may be presented with the use of logarithmic scale; comparing to the linear scale signals presentation
the logarithmic scale presentation will not depend on the Gain setting, which defines just the position of 3 parallel lines above the logarithmic A-Scan:
the upper line corresponds to 100% level of the linear scale A-Scan
the lower line corresponds to 1% level of the linear scale A-Scan
the middle (red) line corresponds to 50% level of the linear scale A-Scan
In the Dual A-Scan mode the observation of the signals with use of the linear and logarithmic vertical scale is possible:
The instrument screen video below illustrates the versatility of the time domain signal presentation in the ISONIC 3507's channel
The receiver of each ISONIC 3507's channel is equipped with 32-Taps FIR band pass with controllable lower and upper frequency limits. This allows improving of the signal to noise ratio for both traditional and
non-linear acoustics technique based inspections
Note: In order to accelerate the data stream the videos above are linked to the Youtube. In case the YouTube may not be accessed from your location please use the links below
Both channels of ISONIC 3507 are equipped with 2 independent gates (A and B) each; the gates are used for settling of the Region of Interest (ROI), alarming the defect events, and signals evaluation
Each channel carries the ability of Gain per Gate A and Gain per Gate B control over the entire gain manipulation range from –30 through +110 dB independently on the global instrument gain setting:
up to 3 independent gain settings may be acting within the same A-Scan. This opens the opportunity of observation and monitoring of the weak and strong signals simultaneously without any loss of data. The
Gain per Gate settings dominate over the Global Channel Gain; in case of the full or partial matching of the Gate A and Gate B the Gain per Gate A setting has a priority
This functionality is very useful for the large number of inspections where the defects are detected through the receiving of echoes exceeding the certain threshold level and through back wall echo drop
(for example, the back echo attenuator based applications)
The instrument screen movie below illustrates controlling of the Gates A and B, the Alarm Logic, and Gain per Gate:
The Display Delay and Range of the A-Scan may be toggled from the currently applied settings to the Gate view and back as it is illustrated by the instrument screen movie below
For some inspection applications it may be very useful keeping some reference signal at the desired standard level whilst scanning OR bring the signal obtained from the certain region of interest defined by the Gate A
to the standard level. The example of using the normalized A-Scan allowing bringing of the signal from the discontinuity to the desired standard level is illustrated by the video below. The
normalized A-Scan / Artificial Intelligence A-Scan is used at parallel with the regular:
Usually for the immersion inspection it is necessary to start A-Scan upon receiving the interface chow from the material surface – for that purpose each instrument's channel is featured with the IE (interface echo) gate that should
be settled appropriately: the first signal crossing the IE gate level initiates the new A-Scan resettling the Display Delay accordingly following probe to material distance in real time. The process is
illustrated by the video below:
Note: In order to accelerate the data stream the videos above are linked to the Youtube. In case the YouTube may not be accessed from your location please use the links below
Both channels of ISONIC 3507 is featured with 3 ways for creating DAC, TCG. Independently on the way the DAC was created there are provided:
up to 3 additional curves with the operator's selected dB-displacement in +/- 30 dB range
positioning of the main and additional DAC curves according to the Global Instrument Gain manipulated by an operator
one-click toggling between DAC and TCG
varying Display Mode whilst DAC or TCG is active
The instrument screen movie below illustrates the typical DAC/TCG manipulations on the series of back wall echoes whilst using ISONIC 3505:
Experimental DAC
The experimental DAC is created through recording as sequence of echoes from the equal reflectors detected through various sound paths; the maximal capacity 40 echoes (points). The user friendly dialogue
is combined with the Gain per Gate bringing each echo maximum in the Region of Interest defined by the gate position to the commonly used level of 80...90%% FSH automatically and
extremely easing maximizing of each indication taken into the DAC without affecting the Global Instrument Gain setting
The videos below illustrate the examples of preparing experimental DAC for the shear and longitudinal wave inspections with use of SDH (side drilled hole) and FHB (flat bottom hole) artificial reflectors correspondingly:
Theoretical DAC (dB/mm , dB/inch)
For some applications it may be required to create a DAC through entering of dB/mm (dB/inch) factor.
The goal of the calibration is to provide matching the tips of back wall echoes with the DAC line. To start the calibration it is necessary to obtain the A-Scan, on which the amplitude of the first
back wall echo doesn’t exceed 100% FSH; along with keying in dB/mm (dB/inch) factor the DAC may be displaced in the vertical direction
The instrument screen movie illustrating dettling of dB/mm DAC is shown below:
The video showing the whole process is below:
DGS
The expandable database for the standard probes is carried by the instrument allowing using of the DGS technology for the sensitivity calibration and distance amplitude correction. The calibration
is performed in the user friendly dialogue as it is illustrated by the videos below
DGS calibration for 1.5 mm FBH sensitivity with MWB-45-4 probe
DGS calibration for 2 mm FBH sensitivity with MWB-60-2 probe
DGS calibration for 2.4 mm FBH sensitivity with SWB-60-5 probe

Signal Templates
Rapid and simple distinguishing of the signals characterizing evaluated properties of materials, internal discontinuities, etc may be achieved through pre-storing storing of corresponding waveforms template and displaying the live A-Scan
and the templates on the same screen - an example is illustrated by the video below:

Frequency Domain - Ultrasonic Spectroscopy
Probes Characterization
Screening and Evaluation of HTHA Damages
Materials Sorting
The frequency domain signal presentation is available in the ISONIC 3505 through the FFT display mode provided the DAC, DGS, TCG functions are inactive. The FFT graph is accompanied with the time
domain signal presentation – RF mode
The FFT graph may be presented with the use of either linear or logarithmic vertical scale. The instrument screen movie below illustrates the frequency domain signal presentation and evaluation
Thanks to the non-saturated receiver the frequency domain signal presentation doesn't depend on the instrument gain in the ISONIC 3505:
The frequency domain signal presentation is very useful for the probes characterization, express screening or determining of the material properties, defect pattern analysis, and the like
An example of the quick probe characterization is provided in the video below:

Movies for the TOFD Recording and Imaging (with and without mode conversion back echo recording / scanning performed with use of the encoder and scanner):
Typical TOFD record for the weld inspection:
TOFD / CHIME Record Stabilizer
The typical way for settling of the instrument Gain prior to the TOFD inspection is bringing the amplitude of lateral wave signal to the desired standard level, usually - between 30 and 60% of the FSH
(Full Screen Height). Whilst scanning the amplitude of the lateral wave signal may fluctuate due to various reasons such as coupling deviations, inhomogeneity of the weld structure, and the like.
Such fluctuations affect the quality of TOFD record
As ISONIC 3507 carries exceptionally innovative ultrasonic card with never-saturated-receivers, which keep the linearity over 140 dB dynamic range digitizing the originally received signals
independently on the gain and rectification settings in every firing / receiving cycle. This unique feature allows generating of the so called Artificial Intellect (A.I.) A-Scan along with the regular one simultaneously
The A.I. A-Scan is based on the digitizing signal over 140 dB dynamic range (real time 32-bits A/D conversion). For the data digitized in such manner the Gain setting defines not the sensitivity but the scaling factor
applied to the FSH. The A.I. A-Scan allows gating of the signal, for example - lateral wave (or part of it) and real time scaling bringing the highest amplitude within entire Gate to the predefined standard level, for example 60%
Whilst scanning the highest half-wave of the lateral wave signal has been kept at the standard level permanently - this provides the stability and consistency of the TOFD record for the varying coupling conditions
and other factors influencing the quality of the recorded signals as it is illustrated by the instrument screen video below:

Multi A-Scan and Strip Chart
Whilst in single channel operating mode each channel of ISONIC 3507 allows obtaining of several (up to 4) A-Scans out of the same probe (pair of probes) simultaneously in every emitting / receiving cycle. For each A-Scan the following parameters may be settled independently on others:
Timebase: Display Delay and Range
Gain
Signal presentation either RF or rectified
Gates start, width and threshold
Signal evaluation readout
Strip chart may be formed out of the said A-Scans and recorded along the scanning line: each A-Scan represents corresponding section (Region of Interest - ROI) of the material

C-Scan - Raster Scanning
The Single Channel Manual Raster Scanning remains to be the optimal solution for the numerous inspection tasks such as ultrasonic testing of relatively small composite parts, detection of impact damages under the flying
surfaces of aircraft, corrosion mapping, and the like where the mechanic-free probe positioning is desired by most of users
The airborne ultrasound based encoder powered and communicating with the instrument through USB port monitors the probe position and swiveling angle for the conventional / PA probes manipulated over the
flat or curved surfaces. The main module of the encoder carries the electronic box and the bar with airborne ultrasound receivers. Prior to the scanning it is placed onto the part under test or at some proximity
to it by means of either magnetic legs or vacuum cups. The encoder is connected to the ISONIC 3507 instrument via USB cable and the light thin umbilical extending the probe connection terminals. Another light
thin umbilical connects the probe used for the inspection to the corresponding extended terminal(s) and the airborne ultrasound emitter situated on the top of the probe to the electronic box. Single element airborne
ultrasound emitter is sufficient for the XY-positioning of the probe; dual emitter is required for the XYß-positioning where ß is the probe swiveling angle
The probe coordinates on the material and swiveling angle are monitored continuously and transmitted to the inspection software providing capturing of the corresponding A-Scans (conventional modality) and A-Scan sets (PA modality)
for every encoded position along the scanning trace. The inspection software packages for the ISONIC 3507, ISONIC 3505, and ISONIC 3510 instruments allow:
Compression wave flaw detection and thickness (corrosion) mapping of the parts with flat and curved surfaces with use of single or twin element conventional probes and linear array / dual linear PA probes
Short Range Guided Wave (SRUT) inspection of annular rings, pipe walls, tank shells, and the like with use of mono-element SRUT probes and wedged PA probes
Weld inspection with use of PA probes etc
The B-, C-, CB-Scan and 3D data presentation are provided
The exemplary movies for the airborne ultrasound encoded mechanics-free raster scanning and recording:
1. Instruction video on connection of airborne ultrasound encoder to the instrument and to the receivers followed by the calibration for the actual values of airborne ultrasound velocity and sensors delays
2. Instruction video on the XY scanning with 0-degree probes
3. Instruction videos on the XYß scanning with the use of short range guided wave (SRUT GW), angle beam shear wave, surface wave probes
3.1. For the placement of airborne ultrasound receivers in front of the probe
3.2. For the placement of airborne ultrasound receivers behind the probe
4. Screening and mapping of the corrosion damages below the soil level in the steel poles legs (air-to-soil interface)
5. Corrosion (thickness) mapping using 0-degree probe
6. Flaw detection and mapping of composite panels
7. SRUT GW inspection
Use of the water delay / rolling / immersion probes is supported thanks to the interface echo triggering feature
Performing of the automatic XY-scanning in contact / immersion modes is also possible when using optional dual axis encoder interface, which connect the scanner's encoders to the instrument's USB port

IUT – Immersion Ultrasonic Testing
ISONIC 3507, each channel of which is featured with the interface echo function and carrying powerful on-board computer is suitable for the rapid high resolution immersion ultrasonic testing (IUT); the automatic
scanning mechanism is controlled through USB port. The use of an external PC is not a must
An example of the IUT routine including the quick preparing for the inspection, scanning with 100% raw data capturing, and postprocessing is illustrated by the video below

Dual Channel Operation
For the Dual Channel operation the settings of UDS 3-9 Pulser Receiver stored into the corresponding files are used as source for further recording
Depending on the channels settings the strips of the following types may be created in any possible combination:
TOFD
Map
PE
One of the typical applications is Dual Channel TOFD Inspection, which is illustrated by the video below
Capturing of the raw data A-Scans is provided for each strip. Beside the data analysis for the complete strip chart the postprocessing for each strip
may be performed separately according to type of record carried

UT over IP - Remote Control and Data Acquisition
Thanks to the Client – Server software architecture ISONIC 3507 may be controlled remotely from a regular PC running under Win’XP, 7, 8, 10, 11. There is no need in the special software for that purpose,
just download and install in the PC the same software as used in the instrument
The software installed in the PC should be of the same release as the software running in the ISONIC 3507 and correspond to the instrument model
Installing the Instrument Software in the PC
Upon started the installation routine generates the dialogue as below on the PC screen:
It is necessary to check Install client only and uncheck Run on windows startup option then to click on Install button. Further actions are taken by the installation routine automatically
Controlling the Instrument from the PC
The instrument and the computer should be connected to the same LAN or Wi-Fi and obtain the IPs automatically. The initial Startup menu (Start Screen) appearing upon powering the instrument on and booting up completed
should be kept on the unit's screen at the time of establishing the remote connection and control. In the computer the same software should be launched: on appearing of the Startup menu it is necessary to select the instrument
to be controlled from the list of the available Idle units:
Once the connection is established ISONIC 3507 unit enters into the slave mode being connected to the probes and encoder and running the just the server routine while the computer performs full control of the instrument,
data acquisition, processing, and storage on the local drives through running of the client software in the same manner as the instrument does when operating autonomously
The video below illustrates the UT over IP feature:
Extremely simply and quickly implementable UT over IP mode of operation is the standard feature of all ISONIC series portable instruments, namely
For all above listed units the remote control and data acquistion are realized in the same manner as it is shown in the present video

In the ISONIC 3507 the single channel A-Scan mode of operation is used for the various pure A-Scan based inspections and for the calibration purposes prior to the inspections
performed with the data recording through either Line- or Raster- scanning
