Setting The Reference Calibration Factor - Agilent Technologies EPM-P Series Programming Manual

Setting the Reference Calibration Factor

All the 8480 Series power sensors and N8480 Series power sensors with
Option CFT require you to set the reference calibration factor. The
reference calibration factor can be set by:
• entering the value into the power meter using the
CALibrate[1|2]:RCFactor command.
• selecting and enabling the sensor calibration table. The reference
calibration factor is automatically set by the power meter using the
reference calibration factor stored in the sensor calibration table. See
"Using Sensor Calibration Tables", on page 1-41 for further information.
Examples
a) To enter a reference calibration factor of 98.7% for channel A, you
should use the following command:
CAL:RCF 98.7PCT
This overrides any RCF previously set by selecting a sensor
calibration table.
b) To automatically set the reference calibration factor, you have to
use a sensor calibration table as described in "Using Sensor
Calibration Tables", on page 1-41. To select and enable the table
use the following commands:
[SENSe[1]]|SENSe2:CORRection:CSET1:SELect <string>
[SENSe[1]]|SENSe2:CORRection:CSET1:STATe ON
When the sensor calibration table is selected the RCF from the
table overrides any value previously set.
Querying the Reference Calibration Factor
To determine the current reference calibration factor, use the following
command:
CALibration[1|2]:RCFactor?
