4-Port System
1. Connect the VNA extender waveguide Ports 1 and 2 together and Ports 3 and 4
together.
2. Select Preset.
3. Set the power level to +20 dBm
1
.
4. Ensure that the following four traces are each setup in a display window (turn on
"Statistics" for each trace):
a. S12 - Trace Uncorrected Thru
b. S21 - Trace Uncorrected Thru
c. S34 - Trace Uncorrected Thru
d. S43 - Trace Uncorrected Thru
5. Normalize the S12, S21, S34 and S43 traces.
6. Set IF BW to 10 Hz.
7. Separate the VNA extenders and connect a flush short (or load) from the cal kit to
the waveguide test port of each extender. (Note that dynamic range is best
measured with loads, but shorts can be used).
8. Set the scale reference level to -100 dB for each window.
9. Verify the mean value is ≥ -100 dB for each trace.
10. See
Figure 26
below for a display example.

4-Port Dynamic Range Check with Statistics
1. En20 dBm in the VNA menu will result in approxi13 dBm of output at the waveguide test port.
