R&S FSQ Remote Control – Description of Commands
SENSe Subsystem
[SENSe:]BANDwidth|BWIDth[:RESolution]:TYPE NORMal | FFT | CFILter | RRC | P5 |
P5Digital
This command switches the filter type for the resolution bandwidth between "normal" analog or FIR
filters in 1, 3, 10 steps and the FFT filtering for bandwidths 0 Hz.
From firmware version 1.10 onwards, steep-edged channel filters and filters with RRC (Root Raised
Cosine) characteristic are available.
The possible combinations of filter type and filter bandwidth are listed in chapter
“Instrument Functions”, section “Filter Types” on page 4.26.
Type P5 resonates more quickly.
Example: "BAND:TYPE NORM"
Characteristics: *RST value: NORMal
SCPI: device-specific
Mode: A
[SENSe:]BANDwidth|BWIDth:VIDeo 1 Hz to 30 MHz
This command defines the instrument's video bandwidth. Bandwidths from 1 Hz to 30 MHz in 1, 2, 3,
5, 10 steps are available. The command is not available if FFT filtering is switched on and the set
bandwidth is ≤ 30 kHz or if the quasipeak detector is switched on.
Example: "BAND:VID 10kHz"
Characteristics: *RST value: - (AUTO is set to ON)
SCPI: conform
Mode: A
[SENSe:]BANDwidth|BWIDth:VIDeo:AUTO ON | OFF
This command either automatically couples the instrument's video bandwidth to the resolution
bandwidth or cancels the coupling.
The ratio video bandwidth/resolution bandwidth can be modified with the command [SENSe:
]BANDwidth:VIDeo:RATio.
Example: "BAND:VID:AUTO OFF"
Characteristics: *RST value: ON
SCPI: conform
Mode: A
When changing the filter type, the next larger filter bandwidth is selected if the
same filter bandwidth is not available for the new filter type.
