Hi all-
I am demodulating an AM modulated waveform, and would like to display the
time series of the sideband in a window. I have code that uses the scope
sink to do this, but the magnitude is in units which I take to be
correlated to A/D raw values (ie, values near 2000). How do I convert
this to an equivalent voltage? I am using the LFRX daughterboard (DC-50
MHz) to acquire the signal. I know that Charles Swiger has some c-codes
that do this, but I'm not sure which format I'm converting from (4-byte
floating point?) or how to implement that in Python. My code is at:

thanks,
eric
