The 8485d diode power sensor can measure the average power in the frequency range of 50MHz to 26.5ghz and the power range of - 70 to - 20dbm (50 dB dynamic range).
The keysight 11708a 30 dB attenuator is equipped with a series 8480 power probe with the sequence prefix "d", which can be calibrated using a power meter (based on 0 DBM, 50 MHz).
An excellent standing wave ratio reduces the uncertainty of mismatch
Accurate calibration, traceable to the National Institute of Standards and Technology (NIST)
Compatible with EPM (new N1913A/ 14A, E4418B/ 19B), EPM-P (E4416A/ 17A) and P series (N1911A/ 12A) power meters, E1416A VXI, and the discontinued 70100A and 43X
Accurate average power measurements range from -70 to -20 dBm
Frequency range from 50 MHz to 26.5 GHz
