The Agilent/Keysight E9325A is a peak and average power sensor engineered for precision RF power measurement across 50 MHz to 18 GHz. It delivers simultaneous peak and average power readings, making it ideal for characterizing complex modulated signals, pulsed transmissions, radar systems, and wireless communication devices. On-board EEPROM calibration data compensates for frequency, power level, and temperature variations, achieving ±0.04 dB absolute accuracy in logarithmic mode.
Technical Specifications
Frequency coverage spans 50 MHz to 18 GHz. Power measurement range is −60 dBm to +20 dBm in average-only mode and −50 dBm to +20 dBm in normal mode. Video bandwidth is 300 kHz. Absolute measurement uncertainty (log) is ±0.04 dB; relative accuracy (log) is ±0.08 dB. For power levels exceeding 0 dBm, add ±0.1%/dB to calibration factor uncertainty. Zero drift remains below ±5 nW in normal mode and ±60 pW in average-only mode. The sensor delivers up to 1000 corrected readings per second via GPIB.
