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 200 ft*, WireCheck® can simplify difficult troubleshooting tasks on aircraft and other systems where cable access is limited, and/or where faults are intermittent. 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. Low-level 600mV pulses with extremely fast 50psec rise/fall times are injected 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. Scans can be viewed in real-time or saved for post processing.
