The Amplifier Research PM2003 is a three-channel RF power meter engineered for precision measurements across RF and EMC applications. This instrument simultaneously displays two of three available channels on a menu-driven LCD display, delivering measurement speeds up to 200 readings per second in single-channel mode and 100 readings per second with dual channels. The PM2003 operates from 10 kHz to 40 GHz and measures power from −70 dBm to +44 dBm, with dynamic range up to 90 dB when paired with diode power heads and 50 dB with thermocouple heads. All specifications are dependent on the selected PH2000 Series power head.
