R&S ESCI
The FREQUENCY SWEEP softkey opens a table for setting the generator level

as well as the multiplier and the offset used to derive the generator frequency
from the analyzer frequency.
This table also permits configuration of two generators so that switching between
two different configurations is easily possible.

Selects the active generator. Only one generator can be active at a
time. The operating mode of the active generator is set to remote
control in the SELECT GENERATOR table.

Generator Analyzer
Note that the frequencies resulting from start and stop frequency of
the R&S ESCI do not exceed the allowed generator range:
! If the start frequency lies below F MIN, the generator is only
switched on when F MIN is reached.
! If the stop frequency lies above F MAX, the generator is switched
off. When the generator is subsequently switched on using the
EXT SRC ON/OFF softkey, the stop frequency is limited to F
MAX.
! If the stop frequency lies below F MIN, the generator is switched
off and the following error message output:
! In the time domain (Span = 0 Hz) the generator frequency is
derived from the set receive frequency of the R&S ESCI using the
calculation formula.
For the sake of clarity, the formula is also displayed in the table.
