Making Measurements using Sensor Calibration
Tables
This section applies to all HP 8480 series power sensors. It does not apply
to the HP E-series power sensors.
For the HP 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.
