WireCheck is an extremely sensitive Time Domain Reflectometer designed specifically for detecting chafing and other soft faults in cables.

WireCheck is an extremely sensitive Time Domain Reflectometer designed specifically for detecting chafing and other soft faults in cables.

With the ability to detect chafes at sub-inch accuracy to greater than 200ft*, WireCheck Time Domain Reflectometer simplifies difficult troubleshooting tasks on aircraft and other systems with limited cable access and/or where faults are intermittent. Above all, WireCheck comes with common cable attachments. Included Matlab calibration functions dramatically increase sensitivity and dynamic range during post-processing.

Simply connect the instrument leads to the wire-under-test and ground, and start a scan. Likewise, WireCheck injects low-level 600mV pulses with extremely fast 50psec rise/fall times into the cable at a rate of ten million per second. An 18GHz track-and-hold plus 200MHz 12-bit ADC act as a sampling scope to generate a trace of the reflections. In conclusion, view scans in real-time or save them for post-processing.
