FETCH:WAVEform:VOLTage#?
Returns time domain data for voltage on selected phase #. # = 1, 2 or
3. Returns a string of <nr2> type numbers, comma delimited. Only a
single waveform may be queried in a command.
Note: In UPC Compatibility mode, a total of 512 data points are
returned. In LMX mode, 1024 data points are returned.
