Description
Designed specically for Cable TV 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.
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. Move the cursor to the fault and use the one-button
zoom function to pinpoint its location.
The TV90 uses a 6 ns pulse width for close-in resolution. Faults as near as
3 feet from the pedestal are located with ease. Optimized pulsing and sam-
pling, coupled with advanced ltering and signal-processing techniques,
provide a clean waveform for easy event identication.
