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 24. 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:
