The Agilent/Keysight 8900C is an analog peak power meter that delivers direct, real-time display of RF pulse power across a broad frequency spectrum. Purpose-built for pulsed and continuous-wave power measurement, the 8900C connects with the 84811A peak power sensor to characterize pulse widths ranging from 1 µs to CW operation, with pulse repetition rates from 100 Hz to 100 kHz. The instrument’s analog meter face is calibrated in both watts and dBm, enabling rapid field adjustment and optimization of pulsed RF systems without the complexity of digital interfaces.
