Ref Offset
Adds an offset value which ranges from - 327.6 dB
to +327.6 dB to the displayed reference level.
Reference- level offsets are used when gain or loss
occurs between a device under test and the
analyzer input. Thus, the signal level measured by
the analyzer may be referred to as the level at the
input of an external amplitude- conversion device.
When an amplitude offset is entered, its value
appears in the lower left corner of the display.
Key Access:

NOTE
Reference-level offsets are only entered by using the numeric
keypad. Entering an offset does not affect the trace or the
attenuation value.
NOTE
Amplitude units are maintained for both logarithmic and linear
modes depending on the Scale Type setting.
