Measure Match

Antenna manufacturers often use VSWR for specifications. Match Efficiency is popular for testing because it is easy to determine a good match versus a bad match. For example a system with a VSWR of 1.50 would show -13.98 dB Return Loss and 96% Match Efficiency.

Auto Scale vs. Manual Scale

In swept mode Auto Scaling sets the measurement unit scale to make the trace easier to read. However, if you plan to look at the size or shape of traces for quick comparisons, it might be more meaningful to set a standard scale. Remember that it is possible to set the scale manually so the information is not on the display at all.
