N8480 Series Power Sensors (excluding Option CFT)

Power sensors have small errors in their response over frequency. The response of
each sensor is measured during manufacture (and during periodic calibration).
With N8480 Series power sensors (excluding Option CFT), the resulting frequency
compensation information is written into Electrically Eraseable Programmable
Read Only Memory (EEPROM). This allows the frequency and calibration data to
be downloaded to the power meter automatically.
Using calibration factors enables you to achieve improved measurement
accuracy. This section describes making continuous wave measurements using
the N8480 Series power sensors (excluding Option CFT).
Making a measurement requires the following steps:
1 Zero and calibrate the power meter/sensor combination.
2 Set the frequency for the signal you want to measure.
3 Make the measurement.

Procedure

1 First zero and calibrate the power meter/sensor combination.
2 Ensure the power sensor is disconnected from any signal source.
