RBW / VBW
PULSE [.1]
The
RBW/VBW PULSE [.1]
softkey sets the following coupling
ratio:
video bandwidth = 10 x resolution bandwidth or
video bandwidth = 10 MHz (= max. VBW).
This coupling ratio is recommended whenever the amplitudes of
pulsed signals are to be measured correctly. The IF filter is
exclusively responsible for pulse shaping. No additional
evaluation is performed by the video filter.
IEC/IEEE-bus command
BAND:VID:RAT 10
This setting is only effective for the
VBW AUTO
selection in the
main menu.
RBW / VBW
NOISE [10]
The
RBW/VBW NOISE [10]
softkey sets the following coupling
ratio:
video bandwidth = resolution bandwidth/10
At this coupling ratio, noise and pulsed signals are suppressed
in the video domain. For noise signals, the average value is
displayed.
IEC/IEEE-bus command
BAND:VID:RAT 0.1
This setting is only effective for the
VBW AUTO
selection in the
main menu.
RBW / VBW
MANUAL
The
RBW/VBW MANUAL
softkey activates the manual input of
the coupling ratio.
The resolution bandwidth/video bandwidth ratio can be set in the
range 0.001 to 1000.
IEC/IEEE-bus command
BAND:VID:RAT 10
This setting is only effective for the
VBW AUTO
selection in the
main menu.
SPAN /RBW
AUTO [50]
The
SPAN/RBW
AUTO [50]
softkey sets the following coupling
ratio:
resolution bandwidth = span/50
This coupling ratio is the default setting of the R&S FSMR
IEC/IEEE-bus command
SENS:BAND:RAT 0.02
This setting is only effective for the
RBW AUTO
selection in the
main menu.
