"Manual"
For manual mode, define the "Sweep Time" . Allowed values depend
on the ratio of span to RBW and RBW to VBW. For details refer to the
data sheet. Numeric input is always rounded to the nearest possible
"Sweep Time" .
Remote command:
[SENSe:]SWEep:TIME:AUTO on page 897
Span/RBW
Sets the coupling ratio if RBW is set to auto mode.
For more information see Chapter 8.5.1.4, "Coupling Span and RBW", on page 378.
"Auto[100]"
"Resolution Bandwidth" = "Span/100"
This coupling ratio is the default setting of the R&S FSV/A.
"Manual"
The coupling ratio is defined manually.
The span/resolution bandwidth ratio can be set in the range from 1 to
10000.
Remote command:
[SENSe:]BANDwidth[:RESolution]:RATio on page 892
RBW/VBW
Sets the coupling ratio between the resolution bandwidth and the video bandwidth.
This setting is only effective if VBW is set to auto mode.
For more information see Chapter 8.5.1.3, "Coupling VBW and RBW", on page 378.
"Sine[1/1]"
"Video Bandwidth" = "Resolution Bandwidth"
This is the default setting for the coupling ratio RBW/VBW and is rec-
ommended if sinusoidal signals are to be measured.
"Pulse[0.1]"
"Video Bandwidth" = 10 x "Resolution Bandwidth"
or
"Video Bandwidth" = "10 MHz" (= max. VBW)
Recommended for pulse signals
"Noise[10]"
"Video Bandwidth" = "Resolution Bandwidth/10"
Recommended for noise measurements
"Manual"
The coupling ratio is defined manually.
The RBW/VBW ratio can be set in the range of 0.001 to 1000.
Remote command:
[SENSe:]BANDwidth:VIDeo:AUTO on page 893
[SENSe:]BANDwidth:VIDeo:RATio on page 894
Filter Type
Defines the filter type.
The following filter types are available:
●
Normal (3dB)
●
Channel
