Reflectometer Makes It Simple for CATV Techs


This TDR500/3-CTVhelps to simplify locating events including bends, crimps, cuts, shorts, opens and water saturation on coax cables.
With a maximum range up to 15,000 feet, the TDR500/3 has a ‘dead zone’ of only 3 feet.

The handheld, time domain reflectometer, designed for CATV service technicians, aids in the quick diagnosis of the TDR trace. An auto set-up option helps determine the impedance of the cable under test, sets the unit accordingly and selects the optimum gain and pulse width. Technicians can also manually adjust the unit’s controls to ensure that any event of interest is fully visible on the set’s extra high resolution backlit screen.  A unique trace hold feature allows technicians to view a trace later.
