With a frequency range greater than 2 GHz, LPT-2010A RF power meter is simple to operate. The input level range is -20 dBm (0.01 mW) to more than 23 dBm (200 mW). Operators turn on, press the RANGE button to select one of four power ranges, press zero to null the meter, apply power and read the results on the 3-1/2-digit LCD. A hold button lets users freeze the display and remove power.
