Power Meter Operation
Making Measurements using Sensor Calibration Tables
2-22 HP E4418B User’s Guide
The power meter is shipped with a set of predefined sensor calibration
tables. The data in these tables is based on statistical averages for a range
of Hewlett-Packard power sensors.
These power sensors are:
• DEFAULT
1
• HP 8481A
• HP 8482A
2
• HP 8483A
• HP 8481D
• HP 8485A
• R8486A
• Q8486A
• R8486D
• HP 8487A
There are also ten sensor calibration tables named CUSTOM_0 through
CUSTOM_9 which do not contain any data when the power meter is
shipped from the factory.
You cannot delete any of the 20 sensor calibration tables. Each sensor
calibration table can contain a maximum of 80 frequency points each. If
you want a new sensor calibration table you must edit an existing one.
To edit a table:
1. Select one using the and hardkeys to scroll through the
displayed tables. When the table you want to edit is highlighted
press . The “Edit Cal” screen is displayed as shown
in Figure 2-5 on page 2-21. In this screen you can modify, add and
remove frequency and calibration factors and also edit the table
name. Use the , , and hardkeys to move
between the table name and its frequency and calibration factors.
A frequency in the range of 0.001 MHz to 999.999 GHz can be
entered.
1. DEFAULT is a sensor calibration table in which the reference calibration
factor and calibration factors are 100%. This sensor calibration table can be
used during the performance testing of the power meter.
2. The HP 8482B and HP 8482H power sensors use the same data as the
HP 8482A.
