Connect a load to PORT 2, and press:
11.
12. Connect the load to PORT 1, and press:
13. You may repeat any of the steps above. There is no requirement to go in the order of
steps. When the analyzer detects that you have made all the necessary measurements, the
The message COMPUTING CAL COEFFICIENTS will appear, indicating that the analyzer is
performing the numerical calculations of error coefficients.
Note
You can save or store the measurement correction to use for later
measurements Refer to the "Printing, Plotting, and Saving Measurement
Results" chapter for procedures.
14. Connect the device under test. The device S-parameters are now being measured.
