1. Attach a flush short to the port of the mm-wave extender to be tested.
(Note that two ports can be tested at a time with the cal kit).
2. Select Preset.
3. Set IF Bandwidth to 100 Hz.
4. Setup traces in separate display windows, with four windows for 2-Port and
eight windows for 4-Port. For Port 1 and 2, setup the following traces:
S11 scale format log mag, scale 0.1 dB
S11 scale format phase, scale 1 degree
S22 scale format log mag, scale 0.1 dB
S22 scale format phase, scale 1 degree.
5. Normalize each trace and turn on "Statistics."
6. If the system has been on for less than one hour, some drift is expected.
Measurements are to be made in a stable temperature environment.
Amplitude stability and trace noise: ± .15 dB
1
Phase drift and noise: ± 2 degrees
