I am trying to use Python to control the oscilloscope via the IVI-COM drivers.

So far, i have been successful in creating the object and configuring the channel such as horizontal and vertical setup via Python using the comtypes library.  

But i have a problem understanding how to access the ReadWaveformMeasurement and FetchWaveformMeasurements function.  

I created a measurement object on Channel 1 with this command


But how do i proceed to do a measurement such as rise time of the signal on Channel 1 ? Specifically what arguments do i pass into meas.FetchWaveformMeasurement( ??, ??)
