Test Description
The Input VSWR test measures the worst case VSWR over each of the
specified frequency bands detailed in the Table 2-1 on page 22. The test
measures VSWR directly from the Network Analyzer, however the
conversion below can be used if measuring return loss.
VSWR or voltage standing wave ratio can be calculated from the
reflection coefficient using the following equation:
