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"
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
3 Specify the frequency of the signal you want to measure. The
4 Make the measurement.
