REF<x>:VERTical:POSition
Description
This command sets or queries the vertical position of a reference wave-
form The reference waveform is specified by x. The value of x can
range from 1 through 4 for four --channel instruments or 1 through 2 for
two--channel instruments.
This command is equivalent to selecting Reference Waveforms from
the File menu, choosing Reference Setup… from the drop--down list,
selecting a reference waveform, and then entering the Position value
using the multipurpose knob.
Increasing the position value of a waveform causes the waveform to
move up, and decreasing the position value causes the waveform to
move down. Position adjusts only the display position of a waveform.
The position value determines the vertical graticule coordinate at which
signal values are displayed. For example, if the position for Reference 3
is set to 2.0, the signal represented by that reference will be displayed at
2.0 divisions above the center of the screen.
Note: References are static. All position and scale changes are applied
in a post--processing mode.
