Subject: Problem reading oscilloscope binary waveform output 

I have saved some waveforms using the oscilloscope application in both binary and xml.  I can see that the xml file gives me proper data values but when I try to read the binary file using IDL, it does not seem correct.  This is a screen shot of the pulse I saved: test_pulse.png

But when I open the binary file in IDL using:

data = uintarr(1024)       ;unsigned integer array
readu,lun1,data
free_lun,lun1
close,lun1

;Convert bits to Volts
data=data*0.000015259-0.5        

window,0,xs=512,ys=512
plot,data[*]

I get: pulse_IDL.png

It looks like the pulse is there but there is something corrupting the data only in binary form.  Is there a setting that may not be correct?

Thanks, Ron
