As I mentioned in an earlier post, the CAT commands concerning DSP filters were broken when we added filter selections by operating mode and haven't been fixed yet.
ZZFI is usable if you ignore the filter frequencies shown in the CAT dictionary. ZZFI has legitimate paramters from 00 to 11 where 00 will select the upper left button in the DSP filter button group and 11 will select the lower right button. Sequencing through the commands, 01 will select the second button, top row, 03 will select the first button on the second row, and so on. The actual DSP filter width will depend on which mode you have selected and will be whatever the selected switch represents in the current mode. SL and SH originally selected the low cut and high cut frequencies for VAR1. They still do (kinda, sorta) but I would not recommend using them as they presently have a reset problem. A previously selected value gets reset to whatever default you have set for that button/mode when you select the opposite command (i.e., SL resets SH and vice versa). As soon as I can find some spare time I'll see what I can do about fixing them.

I use "CAT" commands from my interface to PowerSDR to control the SDR1000. I want to set the receive bandwidths appropriate to the type of signal. E.g., SSB at 2800 Hz, AM at 6000 Hz, etc. Where can I find a description of the effect of setting ZZFI, SL, and SH? They don't seem to correlate. -- No virus found in this outgoing message.
