Making Measurements with the HP E-Series Power
Sensors
This section describes how to make continuous wave measurements using
the HP E-series power
sensor calibration tables stored in EEPROM. This allows the frequency
and calibration data to be downloaded to the power meter automatically.
To make measurements, perform the following steps:
1. Zero and calibrate the power meter.
2. Set the frequency for the signal you want to measure.
3. Take a reading.

Procedure

The following procedure details how to make a measurement on channel A
of the power meter. To make a measurement on channel B use the same
procedure using the equivalent channel B softkeys.
1. Ensure that no power is applied to the power sensor.
