Power Meter Operation
Making Measurements using Sensor Calibration Tables
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
These power sensors are:
•DEFAULT1
•HP 8481A
•HP 8482A2
•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 Edit Cal Table . The “Edit Cal” screen is displayed as shown in Figure
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 0.1 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.
