<NR1> = 0 turns o
ff the display of the specified channel waveform; any other
value turns on the display of the specified waveform.
Examples
SELECT:CH1 O
N
displays Channel 1.
SELECT:CH1? might return SELECT:CH1 1 indicating Channel 1 is displayed.
SELect:CONTROl <wfm>
This command sets or queries the waveform that is selected as the implied
recipient of channel-related commands that support legacy-style programs. The
command form also performs the equivalent of a SELect:<wfm> ON command.
This command is equivalent to selecting Measureme nt Setup from the Measure
menu and either viewing or setting the Source waveform.

Syntax
SELect:CONTROl {CH<x>|MATH<x>|REF<x >}
SELect:CONTROl?
Arguments
CH<x> se lects the specified channel waveform as the waveform that is affected by
the front panel controls. The x variable can be expressed as an integer ranging
from 1 through 4.
MATH<x> selects the specified math waveform as the waveform that is affected by
the front panel controls. The x variable can be expressed as an integer ranging
from 1 through 4.
REF<x> selects the specified reference waveform as the waveform that is affected
by the front panel controls. The x variable can be expressed as an integer ranging
from 1 through 4.
Examples
SELECT:CONTROL CH2 resets acquisition displays on Channel 2, and causes the
selected waveform to be the implied object of waveform commands.
SELECT:CONTROL? might return :SELECT:CONTROL MATH3, indicating that
Math 3 is the implied object of waveform commands.
SELect:<wfm>
This command turns on the di
splay of a specified waveform and also resets the
acquisition. The query returns whether the channel is on or off but does not
indicate whether it is the selected waveform. WFM can be a channel, math, or
reference waveform.
