Hi All,

I have been trying to provide calibration data for our 24-hour displays, by 
going to Settings > Channel Control > DC Offset, putting in a number, then 
watching how far the trace moves up/down.  Knowing the instrument 
sensitivity per count, I can translate that into velocity units per 
line.  I had been assuming that the number I was entering for the DC Offset 
is always representing counts, but now I am not so sure.

Does anyone know how that works?

BTW I am getting frequent short data dropouts in the output display.  I 
have tracked that down to the possibility that I don't have enough RAM 
(512MB) and am planning to add some more to see if that makes things better.

Thanks,
Brett
