If your job is to find faults on coaxial cable, the Tempo CableScout® TV90 is built for you. Designed specifically for CATV and other coaxial cable applications, the TV90 applies the newest technology to provide both ease of use and coaxial cable testing performance not found in any other TDR. With the TV90, you’ll spend less time operating the TDR and more time repairing faults. Simply select the cable type to be tested and the TV90 does the rest. Pulse width, VP, gain, and vertical position are automatically selected and adjusted as you scan the cable. Finding the fault couldn’t be faster, just move the cursor to the fault and use the one-button zoom function to pinpoint its location.

On the performance side, the TV90 employs optimized pulsing and sampling, coupled with advanced filtering and signal-processing techniques. You always have a clean waveform for easiest event identification.
