This handheld transmission line test set will allow you to optimize your testing reequirements.

The unit features a tone generator with selectable output levels of -13 dBm and 0dBm. It performs True RMS level measurements from -50 dBm to +8 dBm. Its capable of 600/900 Ohm terminated or higher impedance measurements.

A versatile mulitmeter (DCV, ACV, DCA and resistance measurements) and frequency counter (20KHz) are also provided.
Additionally, the unit can withstand drops of up to 10 feet.
