Diode Power Sensor (50 MHz to 26.5 GHz)
The 8480 series power sensors are used for measuring the average power supplied by an RF or microwave source or device-under-test (DUT). In use, the Power Sensor is connected to the RF or microwave source and to a compatible power meter.
The 8480 series power sensors place a 50-ohm load on the RF or microwave source, except the 8483A which has a 75-ohm load. The power meter indicates the power dissipated in this load in mW or dBm.
A Keysight 11708A 30 dB attenuator is supplied with 8480 series power sensors with the “D” suffix, for calibration with the power meter 0 dBm, 50 MHz references.
