R&S FSL SENSe Subsystem
1300.2519.12 6.175 E-11
SENSe:BANDwidth Subsystem
This subsystem controls the setting of the instruments filter bandwidths. Both groups of commands
(BANDwidth and BWIDth) perform the same functions.
Commands of the SENSe:BANDwidth Subsystem
– [SENSe<1|2>:]BANDwidth|BWIDth[:RESolution]
– [SENSe<1|2>:]BANDwidth|BWIDth[:RESolution]:AUTO
– [SENSe<1|2>:]BANDwidth|BWIDth[:RESolution]:RATio
– [SENSe<1|2>:]BANDwidth|BWIDth[:RESolution]:TYPE
– [SENSe<1|2>:]BANDwidth|BWIDth:VIDeo
– [SENSe<1|2>:]BANDwidth|BWIDth:VIDeo:AUTO
– [SENSe<1|2>:]BANDwidth|BWIDth:VIDeo:RATio
– [SENSe<1|2>:]BANDwidth|BWIDth:VIDeo:TYPE
[SENSe<1|2>:]BANDwidth|BWIDth[:RESolution]
This command defines the analyzers resolution bandwidth.
The available resolution bandwidths are specified in the data sheet. For details on the
correlation between resolution bandwidth and filter type refer to chapter "Instrument Functions",
section "To choose the appropriate filter type".
If the resolution bandwidth is modified, the coupling to the span is automatically switched off.
The numeric suffixes <1|2> are not relevant.
Parameter
refer to data sheet
Example
BAND 1MHz
Sets the resolution bandwidth to 1 MHz
Characteristics
*RST value: – (AUTO is set to ON)
SCPI: conform
Mode
all, except ADEMOD
[SENSe<1|2>:]BANDwidth|BWIDth[:RESolution]:AUTO
This command either automatically couples the resolution bandwidth of the instrument to the
span or cancels the coupling.
The automatic coupling adapts the resolution bandwidth to the currently set frequency span
according to the relationship between frequency span and resolution bandwidth. The 6 dB
bandwidths 200 Hz, 9 kHz and 120 kHz and the channel filters available are not set by the
automatic coupling.
The ratio resolution bandwidth/span can be modified with the
[SENSe<1|2>:]BANDwidth|BWIDth[:RESolution]:RATio command.
The numeric suffixes <1|2> are not relevant.
