Syntax

SELect:{BUS<x>|B<x>} {OFF|ON|0|1}

SELect:{BUS<x>|B<x>}?

Arguments

ON or 1 turns the speciﬁed waveform display on.

OFF or 0 turns the speciﬁed waveform display off.

SELect:CH<x>

Turns the display of the channel <x> waveform on or off, where <x > is the

channel number, which can be 1–4. This command also resets the acquisition.

The query returns whether the channel is on or off but does not indicate whether

it is the speciﬁed waveform.

Syntax

SELect:CH<x> {ON|OFF|1| 0}

SELect:CH<x>?

Arguments

ON or 1 turns on the display of the speciﬁed waveform. This waveform also

becomes the selected waveform.

OFF or 0 turns off the display of the speciﬁed waveform.

Examples

SELECT:CH2 ON turns the channel 2 waveform display on, and selects channel 2.

SELECT:CH1? might return :SELECT:CH1 1 indicating that channel 1 is being

displayed.

SELect:CONTROl

This command selects a waveform to be used with channel-related commands

such as the cursor commands. In addition to selecting the waveform, it turnson

the display of the waveform, if it wasn’t on already.

SELect:CONTR

Ol?

Arguments

CH1–4 speciﬁes a channel waveform as the waveform affected by the front-panel

controls.

MATH speciﬁes the math waveform as the waveform that is affected by the

front-panel controls.

BUS1–4 speciﬁes a bus waveform as the waveform affected by the front-panel

controls.

D0–D15 speciﬁes a digital waveform as the waveform affected by the front-panel

controls. (MSO/MDO4000/B models only as well as MDO3000 and MDO400C

models with option MDO3MSO or MDO4MSO installed.)

RF_AMPlitude|RF_FREQuency|RF_PHASe (MDO4000/B/C models only)

and

RF_NORMal|RF_AVErage|RF_MAXHold| RF_MINHold specify an RF

trace as the waveform affected by the front-panel controls.

Returns

NONE if all the channels are turned off. NONE is ignored on input.

Examples

SELECT:CONTR

OL CH2

resets acquisition displays on channel 2, and causes the

selected waveform to be the implied object of waveform commands.

SELECT:CONT

ROL?

might return :SELECT:CONTROL MATH indicating that math

is the implied object of waveform commands.

SELect:DAll (No Query Form)

This command turns on or off all digital channels (D0 — D15).

NOTE. This command applies only to MSO/MDO4000/B models only as well

as MDO3000 and MDO400C models with option MDO3MSO or MDO4MSO

SELect:CONTRO

l:SELect:CONTROl:SELect:D<0-15>

SELect:D<x>

Arguments

This command takes a Boolean argument, which means it can be used to either

turn all digital channels on or all digital channels off.

Examples

SELect:DAll 1 turns on all digital channels.

SELect:D<x>

Turns on the display of the digital channel <x> and resets the acquisition. <x > is

the channel number, which can be 0–15. The query returns whether the channelis

on or off but does not indicate whether it is the selected waveform.

Syntax

SELect:D<x> {<NR1>|OFF| ON}

SELect:D<x>?

Arguments

ON turns on the display of the speciﬁed waveform. This waveform also becomes

the selected waveform.

OFF turns off the display of the speciﬁed waveform.

<NR1> = 0 turns off the display of the speciﬁed waveform; any other value turns

on the display of the speciﬁed waveform.

Examples

SELECT:D2 ON turns the digital channel 2 waveform display on, and selects

digital channel 2.

SELECT:D2? might return : SELECT:D2 1 indicating that digital channel 2 is

being displayed.

SELect{:MATH|:MATH1}

Turns on and off the display of the math waveform. The query returns whether

the math waveform is on or off but does not indicate whether it is the selected

waveform.
