Scope waveform capture is >300x actual waveform voltage

[hammer3]

This is my first time working with the Agilent DSO6054A scope, and I'm trying to capture and save the calibration waveform as a beginning exercise. See attached vi and screenshot. The waveform is really 2.61vpp and the Labview scaled graph is correct on the timebase but the voltage is too high by a factor of ~315. I don't understand why the Y axis scale is wrong. Any help?

You left out the driver vi's for the scope, so all we have arre three empty, greyed out boxes with a time delay between the first two.

where does the front panel control "sense value" come from, and to which of the sub-vi'sdoes it connect?

Sorry I forgot to include the Agilent driver. I attached the .llb file to use with the previously attached vi.

The scaling is done is the Fetch Analog Waveform.vi.  Open its block diagram and probe the scale factors while it is running to see what values are returned from the instrument.  The VI has som enoste desctibeing how the calculation is done.

Thank you all for your patience. I discovered I needed to include Initialize.vi to make the calculations come out right. I wrongly assumed I'd get an error message if it required Initialize.
