Making Measurements using Sensor Calibration Tables
This section applies to all Agilent 8480 Series power sensors and N8480 Series
power sensors with Option CFT. It does not apply to the Agilent E- Series
power sensors and N8480 Series power sensors (excluding Option CFT) .
For the Agilent 8480 Series power sensors and N8480 Series power sensors
with Option CFT, there are two methods of providing correction data to the
power meter:
a inputting the individual calibration factor for a frequency prior to
making the measurement, or
b using sensor calibration tables.
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.
Using sensor calibration tables provides you with a quick and convenient
method for making power measurements over a range of frequencies using one
or more power sensors. The power meter is capable of storing 20 sensor
calibration tables of 80 frequency points each.
To use sensor calibration tables you:
1 Select the table to work on a channel. Refer to “Selecting a Sensor
Calibration Table” on page 45 for further information. If you are
required to edit the table, refer to “Editing Sensor Calibration
Tables” on page 46 for further information.
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. Refer to
“Making the Measurement” on page 45 for further
information.
4
Make the measurement.
