The TS90 is designed for ease-of-use. You'll spend less time operating the TDR and more time repairing faults. Simply select the cable type to be tested and the TS90 does the rest. Impedance, Vp, gain, pulse width and vertical position are automatically selected and adjusted as you scan the cable. Just move the cursor to the fault to pinpoint its location.

On the performance side, the TS90 employs optimized pulsing and sampling coupled with advanced filtering and signal processing techni- ques to insure the maximum measurement range. That way, you'll always have a clean waveform for easier fault interpretation.

Short Pulse Width

The TS90 provides a 5 ns pulse width for close-in resolution. Faults as near as 3 ft. from the pedestal can be located with ease.

Rugged Package

Best of all, you get all this performance in a rugged handheld TDR package. Come snow, rain, heat and humidity, the TS90 keeps working, because you have to.
