Arguments
<NR3> is the desired position, control in divisions from the center horizontal
graticule. The range is from -5 to 5 divisions.
Examples
REF2:VERTICAL:POSITION 1.3E+00 positions the Reference 2 waveform
input signal 1.3 divisions above the center horizontal graticule.
REF1:VERTICAL:POSITION? might return :REF1:VERTICAL:POSITION
-1.3000E+00
, indicating that the current position of Reference 1 waveform is
1.3 divisions below the center horizontal graticule.
REF<x>:VERTical:SCAle
This command sets or queries the vertical scale of a reference waveform. The
reference waveform is specified by x. The value of x can range from 1 through
4. 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 Sca le value using the multipurpose knob.
Each waveform has a vertical scale parameter. For a signal with constant
amplitude, increasing the Scale causes the waveform to be displayed smaller.
Decreasing the scale causes the waveform to be displayed larger.
Scale affects all waveforms, but a ffects reference and math waveforms differently
from channel waveforms:
For reference and math waveforms, this setting controls the display only,
graphically scaling these waveforms and having no affect on the acquisition
hardware.
For channel waveforms, this setting controls the vertical size of the acquisition
window as well as the display scale. The range and resolution of scale
values depends on the probe attached and any other external factors you have
specified.
