- Notes
- The Model 431B Power Meter, with temperature compensated thermistor mounts, measures RF power from 10 microwatts (-20 dbm) to 10 milliwatts (+10 dbm) in the 10 MHz to 40 GHz frequency range. Direct reading accuracy of the instrument is ±3% of full scale. The Model 431B has provisions for using the DC substitution method of measurement and for checking calibration accuracy of the power meter. The DC substitution method of measurement provides greater power measurement accuracies than can be obtained by the power meter.
