Measure Return Loss (Cat) - Keysight Technologies FieldFox N9927-90002 Quick Reference Manual

Measure Return Loss (CAT Mode)
Return loss can be thought of as the absolute value of
the reflected power as compared to the incident power.
When measuring an OPEN or SHORT, all incident power
is reflected and 0 dB return loss is displayed.
When measuring a LOAD, very little power is reflected
and values of 40 dB to 60 dB are displayed.
