

Input VSWR (unloaded) Specification: < 2.5 800 MHz ~ 1 GHz, 1.5 GHz ~ 6 GHz

1) Set the Network Analyzer as follows:



Start: 30 kHz



Stop: 6000 MHz



Measure: S11



Format: SWR

2) Calibrate the Network Analyzer in order to measure S11.

3) Connect the calibrated cable to the input port of TC-5062C and measure SWR.

4) Verify S11 SWR of-5062C meets its specification.
