Peak-Power Measurements Using a Peak-Power Ratio Generator and a Dual-Channel, True-Power-Release Power Meter

摘要

A signal-processing module permits peak-power measurements on a dual-channel, true-power-response power meter. Operation is based on the constant peak-power output of a hybrid analog/digital loop. The peak current of a tunnel diode serves as the high-bandwidth, stable-reference levels for the loop. Measurement accuracy is +0, -0.35 dB for pulse widths of greater than or equal to6.7 ns and pulse repetition frequencies up to 75 MHz. Basic measurement range is from +10 to +36 dBm. Calibration is in terms of a known continuous-wave signal - typically +10 dBm. (ERA citation 11:034699)
