* This value meas that the digital filter is working with "neutral" coefficients
and only the analog anti-alias filter is active. The physical cut-off frequency
may be card dependent.
Virtual subchannels (channel 9) do not support filters. Setting parameters p1,
p2 (and p3) is allowed but will be ignored !
Note: Response depends on SRB command.
SFC?
Syntax 1: SFC?(x)
Parameter: none
Response: q1,q2(y)
q1 Filter characteristics
q2 Cut­off frequency
Syntax 2: SFC??(x)
Parameter: none
Response: q1,q2(y): possible filter characteristics
e.g. 141,142:141,142
Syntax 3: SFC?142,?(x)
Response: q1,...,qn(y): available Bessel frequencies
e.g.
914,917,921,927,931,935,941,945,949,955,958,962,969,973,
1150:914,917...
