Analog Output - R&S AFQ100A Operating Manual

R&S AFQ100A

Analog Output

The parameters offered in the Analog Output dialog depend on the selected output type, balanced or
unbalanced. Two different amplitude modes, Electronic or Attenuators, are available. They determine
how precise the signals will be adjusted.

outputs. The analog I/Q signal components are output
at the I / Q and I BAR / Q BAR connectors on the front
panel of the instrument. A bias for setting the operating
point of the DUT can be defined. In addition an offset
between the inverting and the non-inverting output can
be set to balance a difference of the best operating
points.
Thus, the R&S AFQ provides symmetrical signals for
differential inputs of DUTs without needing external
electric network additionally.
