If the XARGS are not supplied, then the filter parameters will simply retain
their previous values. Thus, CFGINTF with no XARGS can be used to turn
the interference filters On/Off without making any other changes to their
threshold constants. Likewise, if only XARG 1 is supplied, then that single
threshold value will be used for both C1 and C2.

7.24 Set AFC level (SETAFC)
This command sets the AFC level to a given value. The signed 16-bit span
is identical to GPARM Output #51 which shows the present AFC level,
that is, corresponding to the -100% to +100% AFC range that is defined in
the Mb menu. The RVP900 will automatically convert the new level into
whatever analog or digital AFC output format has been configured. The
only exception is for the Motor/Integrator type of AFC loop, in which case
this command does nothing.
Filter Chooses which interference algorithm should be run. See
Section 6.1.5 Interference Filter on page 189 for a
description of the available algorithms.
0: None (Interference filtering is disabled)
1: Alg.1 (Traditional JMA Algorithm)
2: Alg.2 (Alg.1 optimized for additive interference)
3: Alg.3 (Alg.2 with better statistics)
We recommend that you choose Alg.3 for general
operational use. The other algorithms are included mostly
for historical reasons.
