CH<x>:SCAle
Description
This command sets or queries the vertical scale of the specified chan-
nel. The channel 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. Sending this command is equivalent to selecting Vertical
Setup from the Vertical menu and then viewing or setting the Scale.
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 dis-
played larger.
Scale affects all waveforms, but affects channel waveforms differently
from other waveforms:
H 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.
H For reference and math waveforms, this setting controls the display
only, graphically scaling these waveforms and having no affect on
the acquisition hardware.
