Source Offset
Constant level offset for the external 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 "LVL"
label in the channel bar (see also
"Displayed Information and Errors" on page 341).
With this offset, attenuators or amplifiers at the output connector of the external 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 external generator.
