Calibrating for Increased Measurement Accuracy
Power Meter Measurement Calibration
❏ If you are modifying the frequency, enter the new value, followed by a , ,
or key.
❏ If you are modifying the correction factor, enter the new value, followed by the
key.
4. Press after you have finished modifying the segment.
5. If you want to edit any other segments, press and follow the previous steps,
starting with step 2.
Deleting Frequency Segments
1. Access the Segment Modify menu by pressing
(or ,
depending on where the segment is that you want to delete).
2. Identify the segment that you want to delete by pressing and using the
and keys to locate and position the segment next to the pointer (>), shown
on the display. Or press and enter the segment number followed by .
3. Press .
The analyzer deletes the segment and moves the remainder of the segments up one
number.
4. You could also delete all the segments in a list by pressing .
5. Press when you are finished modifying the segment list.
Compensating for Directional Coupler Response
If you use a directional coupler to sample power in your measurement configuration, you
should enter the coupled arm power loss value into the power loss table, using the
following procedure. You can enter the loss information in a single segment, and the
analyzer will assume that the value applies to the entire frequency range of the
instrument. Or, you can input actual measured power loss values at several frequencies
using up to 12 segments, enhancing power accuracy.
1. Press .
The analyzer shows the notation EMPTY, if you have not entered any segment
information.
2. To create the first segment, press and enter a frequency of a
correction factor data point, followed by the appropriate key: .
3. Press and enter the power loss that corresponds to the attenuation of the
directional coupler (or power splitter) at the frequency that you have entered in the
previous step. Complete the power loss entry by pressing .
