HP 8484A High Sensitivity Power Sensor
measures power from 0.1nW to 10 uW over a frequency
range of 10MHz to 18GHz. It is furnished with the 11708A
50MHz reference attenuator for precise calibration with
1 mW power meter reference oscillator. Noise and drift
have been reduced to less than 5% of full scale on the
300 pW range (only 15 pW) when it is used with the 435B
power meter. Noise and drift are even less with the
436A, 437B and 438A power meters.
The 8484A diode
power sensor is designed for use with the EPM series,
EPM-P series, 70100A, E1416A and the 435A/B, 436A,
437A/B, and 438A power meters.
