Input VSWR
Measuring VSWR from 1500 MHz to 3000 MHz
Step 1. Connect the test equipment as shown in Figure 2-4 on page 28.
Step 2. Set the Network Analyzer Start/Stop frequencies from 1.5 GHz to
3.0 GHz.
Press the
Start
key then

Step 3. Set the fixed frequency of the NFA to 1750 MHz (press the
Frequency/Points
key and then

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 and
Mkr Search [ON]
,
Search: Max
).
Step 6. Record the maximum displayed signal frequency and VSWR on the Test
Record.
Step 7. Verify that the measured VSWR from 1500 MHz to 3000 MHz is within
the published specification.
