SENSe:FILTer Subsystem
The SENSe:FILTer subsystem selects the filters in the video signal path.This subsystem is active only in
the Vector Signal Analysis mode (option FSE-B7).

:[SENSe<1|2>:]FILTer:HPASs[:STATe] ON | OFF
This command activates the high-pass filter in the AF-branch for analog demodulation.
Example: "
:FILT:HPAS ON
"
Features: *RST value: OFF
SCPI: conforming
Mode: VA-A
:[SENSe<1|2>:]FILTer:HPASs:FREQuency 30 Hz | 300 Hz
In the Vector Signal Analysis mode with analog demodulation, this command defines the frequency
limit of the high-pass filter in the AF-branch. For REAL TIME ON absolute frequencies are entered,
for REAL TIME OFF, the frequencies are entered relative to the demodulation bandwidth.
Example:
":FILT:HPAS:FREQ 300HZ"
Features: *RST value: - (STATe = OFF)
SCPI: conforming
Mode: VA-A
:[SENSe<1|2>:]FILTer:LPASs[:STATe] ON | OFF
This command activates the low-pass filter in the AF-branch with analog demodulation.
Example:
":FILT:LPAS ON"
Features: *RST value: OFF
SCPI: conforming
Mode: VA-A
On switching to ON, a bandwidth of 3 kHz for REAL TIME ON and a bandwidth of 5 PCT for REAL
TIME OFF is set automatically.
