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:

[AMPTD]

Y Axis Units

Sets the amplitude units.

Key Access:

[AMPTD] > {Y Axis Units}

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.
