Using Sensor Calibration Tables - Agilent 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
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 reference calibration factor for the power meter
you are using.
2. Set the calibration factor to the value for the frequency of the
signal you want to measure.
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.
