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 • 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 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 Thanks to the Client – Server software architecture ISONIC 3507 may be controlled remotely from a regular PC running under Win’XP, 7, 8, 10 over Ethernet or Internet (Sonotron NDT’s UT over IP technology). There is no need in the special software for that purpose, the same software as in the instrument should be installed in the PC ISONIC 3507 is featured with the hardware triggering in/out terminals and the interface echo triggering making it suitable for use in various integrated systems The instrument is fully compatible with the Sonotron NDT's VAUT  technology (Video Aided UT) The lifetime free software upgrade policy is provided for ISONIC 3505 as for all other instruments from Sonotron NDT ISONIC 3507 is packed into the IP 65 reinforced plastic case with no intake air or any other cooling means.
