The relative frequency of the generator signal remains unchanged. By varying the ref-
erence frequency, the fundamental of a distortion spectrum set using a multi-sinewave,
for example, can thus be shifted without the harmonics having to be calculated and set
again by the user.

5.2.2 Outputs of the universal generator
The outputs of the analog R&S UPP generator can be configured in various ways with
regard to Channel and Output Type (see the previous chapter). From serial numbers
120100, 140100, 180100 and higher, the output impedance can be switched between
25
Ω
and 600
Ω
(previously, the impedance was permanently set at 25
Ω
). The sche-
matic circuit diagram for the generator output is shown below.
