As a rule, the R&S FSW supports most commands from previous R&S signal and
spectrum analyzers such as the FSQ, FSP, FSU, or FSV. However, the default values,
in particular the number of sweep points or particular bandwidths, may vary. Therefore,
the R&S
FSW can emulate these other devices, including their default values, in order
to repeat previous measurements or support existing control applications as in legacy
systems.
For R&S FSP/FSQ/FSU emulation, HP commands are not automatically also allowed.
In this case, set
SYSTem:HPADditional
to
ON
.
Note: For PSA89600 emulation, the option is indicated as "B7J" for the
*OPT?
query
("B7J, 140" or "B7J, 122" if Wideband is activated, see
SYSTem:PSA:WIDeband
on page 1333).
Remote command:
SYSTem:LANGuage
on page 1332
IF Gain
Configures the internal IF gain settings in HP emulation mode due to the application
needs. This setting is only taken into account for resolution bandwidth < 300 kHz.
NORM Optimized for high dynamic range, overload limit is close to reference level.
PULS Optimized for pulsed signals, overload limit up to 10 dB above reference level.
This setting is only available if an HP language is selected (see "Language"
on page 790).
Remote command:
SYSTem:IFGain:MODE
on page 1332
Sweep Repeat
Controls a repeated sweep of the E1 and MKPK HI HP model commands (for details
on the commands refer to
Chapter 14.13.2, "Reference: GPIB Commands of Emulated
HP Models" , on page 1334). If the repeated sweep is OFF, the marker is set without
sweeping before.
Note: In single sweep mode, switch off this setting before you set the marker via the
E1 and MKPK HI commands in order to avoid sweeping again.
This setting is only available if a HP language is selected (see
"Language"
on page 790).
Remote command:
SYSTem:RSWeep
on page 1334
Coupling
Controls the default coupling ratios in the HP emulation mode for:
●
span and resolution bandwidth (Span/RBW)
●
resolution bandwidth and video bandwidth (RBW/VBW)
For FSx, the standard parameter coupling of the instrument is used. As a result, in
most cases a shorter sweep time is used than in case of HP.
This setting is only available if a HP language is selected (see "Language"
on page 790).
