Input VSWR
Measuring Input VSWR from 6700 MHz to 20000 MHz
Step 1. Connect the test equipment as shown in Figure 2-6 on page 35.
Step 2. Set the Network Analyzer Start/Stop to measure the DUT’s input VSWR
from 6700 MHz to 20000 MHz.

).
Step 4. Restart the measurement sweep on the DUT (press the
Restart
key).
Step 5. Using the marker peak function on the network analyzer, determine the
maximum displayed VSWR over the measured frequency range (press
the
Marker Fct
n key,
Mkr Search [ON]
then
Search: Max
).
Step 6. Record the maximum displayed signal frequency and VSWR on the Test
Record.
Step 7. Verify that the measured VSWR from 6700 MHz to 20000 MHz is within
the published specification.
