Remote command:
[SENSe:]FILTer<n>:CCIT
SFM:
[SENSe:]SFM:<ChannelType>:FILTer:CCITt:STATe
CCIR Unweighted ← Weighting ← AF Filter ← Left
Switches on the CCIR unweighted filter, which is the combination of the 20 Hz high-
pass and 23 kHz low pass filter. The weighting filter is active in the following demodula-
tion bandwidth range:
50 kHz ≤ demodulation bandwidth ≤ 1.6 MHz
For FM stereo (K7S), the filter is active at all times, as the demodulation range is
always 400 kHz.
Remote command:
[SENSe:]FILTer<n>:CCIR[:UNWeighted][:STATe]
SFM:
[SENSe:]SFM:<ChannelType>:FILTer:CCIR[:UNWeighted][:STATe]

CCIR Weighted ← Weighting ← AF Filter ← Left
Switches on the CCIR weighted filter. The weighting filter is active in the following
demodulation bandwidth range:
100 kHz ≤ demodulation bandwidth ≤ 3.0 MHz
For FM stereo (K7S), the filter is active at all times, as the demodulation range is
always 400 kHz.
Remote command:
[SENSe:]FILTer<n>:CCIR:WEIGhted[:STATe]
SFM:
[SENSe:]SFM:<ChannelType>:FILTer:CCIR:WEIGhted[:STATe]
A Weighted ← Weighting ← AF Filter ← Left
Switches on the A weighted filter. The weighting filter is active in the following demodu-
lation bandwidth range:
100 kHz ≤ demodulation bandwidth ≤ 800 kHz
Remote command:
[SENSe:]FILTer<n>:AWEighted[:STATe]
SFM:
[SENSe:]SFM:<ChannelType>:FILTer:AWEighted[:STATe]
Deemphasis ← AF Filter ← Left
Opens the "Deemphasis" selection list to switch on a deemphasis with the given time
constant.
The deemphasis is active in the following demodulation bandwidth range:
Note: For FM stereo measurements (K7S), the demodulation bandwidth is always 400
kHz, thus the deemphasis is always active.
