Power Meter Remote Operation
Using Sensor Calibration Tables
1-30 Agilent E4418B/E4419B Programming Guide
Using Sensor Calibration Tables
This section applies to all Agilent 8480 series power sensors. It does not
apply to the Agilent E-series power sensors. The Agilent 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 Agilent 8480 series power sensors 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 overides any value
previously set. The power meter is capable of storing 20 sensor calibration
tables of 80 frequency points each.
