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 N1913/1914A EPM 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
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.
