Hello all,

Jim had a question regarding guard filters on the KIMM system.  I did a
little digging and found that for the A/D's we have a 1kHz (software
selectable on/off), the D/A's we have 300Hz filters (software selectable
on/off),  and the 497.22's have a 300Hz filters (software selectable
on/off).

I didn't think there would be a problem with aliasing as long as we
sampled fast enough (Jim was able to stress test the system at 2KHz
update rate).  Could someone please confirm this.

Thanks,
David
