PMR Power Meter
The 3030 RF Power Meter is a modern version of the traditional Antenna Watt and VSWR instrument. The instrument cover communication bands from 30MHz to 500MHz. The 3030 RF Power Meter will measure forward and reflected power in the range from milliWatts up to 100Watts. Built in frequency counter. The counter will show the transmit frequency and will call the calibration table for the actual frequency. Outside the range of the counter the instrument can be set into manual mode giving a wider dynamic range. The 3030 RF Power Meter will calculate VSWR or Return Loss, and features Peak and Hold mode. Accessory kit with soft or hard carrying bag, car charger and coax adapters for standard types are available
