The TV90 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 TV90 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 TV90 employs optimized pulsing and sampling
coupled with advanced filtering and signal processing techniques to ensure the
maximum measurement rante. That way, you'll always have a clean waveform for
easier fault interpretation.
Short Pulse Width
The TV90 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 TV90
keeps working, because you have to.
