               <Description>Sets or returns the vertical position of channel &lt;x&gt;, where x is the channel number. The position value is applied to the signal before it is digitized. Increasing the position value of a waveform causes the waveform to move up. Decreasing the position value causes the waveform to move down. The position value determines the vertical graticule coordinate at which input signal values,
minus the present offset setting for that channel, are displayed. For example, if the position for Channel 3 is set to 2.0 and the offset is set to 3.0, then input signals equal to 3.0 units are displayed 2.0 divisions above the center of the screen (at 1 V/div).

The range is 8 to -8 divisions.</Description>

               <Description>READWAVEFORM Transfer waveforms from the oscilloscope to MATLAB.

[Y, T] = INVOKE(obj, 'readwaveform', CHANNEL) returns a waveform from the instrument,
using channel string, CHANNEL.  Valid channel values are channel&amp;lt;x&amp;gt;, reference&amp;lt;y&amp;gt;, and
math, where &amp;lt;x&amp;gt; is a number between 1 and the number of channels on the instrument and &amp;lt;y&amp;gt; is a letter between A and the number of reference channels on the instrument.

[Y, T] = INVOKE(obj, 'readwaveform', CHANNEL, SCALE) returns the data scaled to real units if SCALE is true, or as raw data if SCALE is false.

To read the waveform data points the interface object associated with the device
object must have a sufficiently large InputBufferSize property value.  If you receive
an error about the buffer size being to small, or have difficulty reading a waveform,
verify that it is large enough.  The size must be greater than two times the number
of points in the waveform, plus approximately 50 bytes for header information.

Example:
	[y, t] = invoke(obj, 'readwaveform', 'channel1');
	[y, t] = invoke(obj, 'readwaveform', 'referenceA', false);

Example changing the buffer size:
	% Note the device object must be closed.
	interfaceObj = get(deviceObj, 'interface');
	% Allow for a 10,000 point waveform with a little extra room.
	set(interfaceObj, 'InputBufferSize', 21000);
	connect(deviceObj);
	[y, t] = invoke(obj, 'readwaveform', 'channel1');
