Agilent / HP / Keysight 8484A

The Agilent / HP 8484A power sensor is used for measuring the average power supplied by RF source to a 50 ohm load.

The Agilent / HP 8484A power sensor is highly sensitive, capable of measuring power levels as low as 0.1 nanowatt (nW).

In use, the 8484A power sensor is connected to the RF source and to a compatible power meter. The suitable power meters are the HP 435B, 436B, 437B and 438A.

The 8484A power sensor places a 50 ohm load on the RF source, and the power meter indicates the power dissipated in this load.

The power is determined from the RF voltage developed across the power sensor load, and is expressed in nW and dBm.

The Agilent 8484A power sensor measures power levels from -70 dBm to -20 dBm at frequencies from 10 MHz to 18 GHz.

Calibration data is provided by a table on the 8484A power sensor. In addition, a table showing the calibration factor to two significant digits is supplied with each power sensor.

The Agilent 8484A power sensor is included with Agilent 11708A 30 dB Reference Attenuator. This is used to reduce the RF reference voltage applied by the power meter to the power sensor when calibrating the system before use.

The option 8484A-002 is a range knob for the Agilent 435A Power Meter, permitting more convenient use of power meters which have serial prefix number 1527A and below.

The option 003 deletes the Agilent 11708A 30 dB Reference Attenuator of the Agilent 8484A Power sensor.
