Sensor Calibration Tables
This section describes how to use sensor calibration tables. Sensor
calibration tables store the measurement calibration factors, for a power
sensor model or for a specific power sensor, in the power meter. They are
used to correct measurement results.
Use sensor calibration tables when you want to make power measurements
over a range of frequencies using one or more power sensors.
The P- Series power meters are capable of storing 20 sensor calibration
tables each containing up to 80 frequency points. The power meter is
supplied with a set of 9 predefined sensor calibration tables plus a “100%”
default table. The data in these tables is based on statistical averages for
a range of Agilent Technologies power sensors. Your own sensor will most
likely differ from the typical to some degree. If you require best accuracy,
create a custom table for each sensor you use as shown
in
“Editing/Generating Sensor Calibration Tables”
on page 187.
To use calibration factor tables:
1
Select the sensor calibration table to be applied to a channel.
2
Zero and calibrate the power meter. The reference calibration factor
used during the calibration is automatically set by the power meter
from the sensor calibration table.
3
Specify the frequency of the signal you want to measure. The
calibration factor is automatically set by the power meter from the
sensor calibration table.
4
Make the measurement.
