Using Sensor Calibration Tables; Overview - Keysight Technologies EPM-P Series Programming Manual

Using Sensor Calibration Tables

This section applies to all 8480 Series power sensors and N8480 Series power
sensors with Option CFT. It does not apply to the E-Series power sensors and
N8480 Series power sensors (excluding Option CFT). All Keysight E-series power
sensors have their sensor calibration tables stored in EEPROM which allows
frequency and calibration factor data to be downloaded by the power meter
automatically.
This section describes how to use sensor calibration tables. Sensor calibration
tables are used to store the measurement calibration factors, supplied with each
power sensor, in the power meter. These calibration factors are used to correct
measurement results.

Overview

For the 8480 Series power sensors and N8480 Series power sensors with Option
CFT, there are two methods of providing correction data to the power meter
depending on the setting of the
[SENSe[1]]|SENSe2:CORRection:CSET1:STATe command. If
[SENSe[1]]|SENSe2:CORRection:CSET1:STATe is OFF the sensor calibration
tables are not used. To make a calibrated power measurement when
[SENSe[1]]|SENSe2:CORRection:CSET1:STATe is OFF, perform the following
steps:
1 Zero and calibrate the power meter. Before carrying out the calibration set the
2 Set the calibration factor to the value for the frequency of the signal you want
3 Make the measurement.
When [SENSe[1]]|SENSe2:CORRection:CSET1:STATe is ON, the sensor
calibration tables are used, providing you with a quick and convenient method for
making power measurements at a range of frequencies using one or more power
sensors. Note that with the sensor calibration table selected, the RCF from the
table overrides any value previously set. The power meter is capable of storing 20
sensor calibration tables of 80 frequency points each.
