on page 905
Power Offset
Constant level offset for the tracking generator. Values from -200 dB to +200 dB in 1
dB steps are allowed. The default setting is 0 dB. Offsets are indicated by the
enhancement label "LVL" in the diagram header (see also
Chapter 8.5, "Displayed
Information and Errors" , on page 500).
With this offset, attenuators or amplifiers at the output connector of the tracking gener-
ator can be taken into account for the displayed output power values on screen or dur-
ing data entry, for example. Positive offsets apply to an amplifier and negative offsets
to an attenuator subsequent to the tracking generator.
