Hi Forrest,
I can think of two approaches: using pvstrace to obtain the n strongest bins 
and work from there.

Or use pvsftw pvsftr and use other analysis mechanisms to find the frequencies 
and amplitudes from there. Probably not really good for extreme live usage.

I am not quite sure whether the track tr* could be of further help.

HTH.

Best wishes,

Jeanette

just to note that there is also pvs2array/pvsfromarray (or in old terms: 
pvs2tab/tab2pvs) which i personally prefer compared to pvsftw/pvsftr:

The f-table needs to be the size of your f-signal, which is set with
pvsanal or something similar. It might still be a lot easier, if you
precede pvsftw by pvsmooth and pvstrace, since the resulting f-table
will be a lot cleaner and easier to work through.

pvsftw has a flag that is set when new data is written. I think this
happens every f-rate cycle. If absolute timing is not that important,
you could just read the f-tables every 100ms or whatever you set the
pvsmooth to. This should work fine.

Best wishes,

Jeanette

AFAIK, the fsig has still the origina number of bins, most are simply 0 now.

That's the way I read it. As suggested you might want to consider using 
pvs2array if you want to control the other instruments from the instrument 
running the FFT analysis dynamically. If everything can be set up fixed pvsftw 
might suite you better. I find f-tables to be more flexibly managed between 
different instruments. A question of taste or style though.

Best wishes,

Jeanette

I'm sorry, I was a little confused. If you have the array output from
pvstrace, you only need N elements of that. If you launch your other
instruments from this one, using any of the schedule or event opcodes,
that is fine. If the other instruments are already running or launch
elsewhere, you can copy the first N elements from the output array to
another global array or create an f-table and use something like
copya2ftab.

Best wishes,

Jeanette
