Making Measurements Using Sensor Calibration Tables; Selecting A Sensor Calibration Table - Agilent Technologies E4418B User Manual

Making Measurements 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.
For the Agilent 8480 series power sensors 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 2-19 for further information. If you require to
edit the table refer to "Editing Sensor Calibration Tables", on page 2-21 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 2-20 for further
information.
4. Make the measurement.

Selecting a Sensor Calibration Table

You can select a sensor calibration table for use by pressing
Sensor Cal Tables Table Off On
sensor calibration tables are currently selected. The "Sensor Tbls" screen is displayed
as shown in Figure 2-4.
