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 55 segments, enhancing power accuracy.
1. Press
Cal PWRMTR CAL
The analyzer shows the notation EMPTY, if you have not entered any segment
information.
2. To create the first segment, press
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
