CH<x>:POSition
Description
This command sets or queries the vertical position of the specified
channel. 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. The position value is applied to the signal before it is digi-
tized. This command is equivalent to selecting Position/Scale from the
Vertical menu and either viewing or setting Position.
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,
whether it is a channel, math, or reference waveform. The position val-
ue 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 divi-
sions above the center of the screen.

CH<x>:POSition <NR3>
Syntax 2
CH<x>:POSition?
Argument
H <NR3>
This is the position value, in divisions from the center graticule, rang-
ing from 8 to --8 divisions.
Example 1
CH2:POSition 1.3E+00
This command positions the Channel 2 input signal 1.3 divisions above
the center graticule.
Example 2
CH1:POSition?
This query might return
:CH1:POSITION -1.3000E+00
indicating that the current position of Channel 1 is 1.3 divisions below
the center graticule.
