2.5.3.11 Pre-amplifier (Electronic Attenuator)
Pre-amplifier (El.Attn.)
is used to turn on the pre-amplifier in the B25 option.
Pre-amplifier (El.Attn.)
is only available when the B25 electronic attenuator option is
installed. Additionally if the B2 option is also installed this parameter is only selectable
when the
Pre-selector
field is switched OFF
2.5.4 Generator Settings
R&S FS-K30 can be used to control an external signal generator in order to generate a Local
Oscillator (
LO
) frequency for noise measurements on frequency-converting DUTs. This
applies for the
Measurement Modes
:
I
Fixed IF, LO = RF + IF
I
Fixed IF, LO = abs(RF – IF)
I
Fixed LO, IF = RF + LO
I
Fixed LO, IF = abs(RF – LO)
The
Measurement Mode
can be selected in the Frequency Settings view by pressing
the
SET FREQ
softkey.
The Generator Settings group of parameters controls the set-up of this external signal
generator.
2.5.4.1 Automatic Control
Automatic Control
defines whether R&S FS-K30 controls the signal generator via GPIB
commands (ON) or whether the signal generator is controlled by the user (OFF).
When
Automatic
Control
is set to OFF, no GPIB commands will be issued to the signal
generator. R&S FS-K30 will assume that the user sets up the signal generator correctly.
None of the other parameters in the Generator Settings group will be available for editing
when
Automatic Control
is set to OFF.
The Manual setting only really makes sense when the
Measurement Mode
is one of
