Command

Description

TRIGger:B:EDGE:SLOpe This command speciﬁes the B edge trigger slope

TRIGger:B:EDGE:SOUrce This command speciﬁes the B edge trigger source

TRIGger:B:EVENTS?

Returns the current B trigger events parameter

B trigger occurs

TRIGger:B:LEVel This command speciﬁes the level for the B trigger

TRIGger:B:LEVel:CH<x> This command speciﬁes the level for the B trigger for a speciﬁc channel

TRIGger:B:LEVel:D<x> This command speciﬁes the B trigger level for digital channel <x>

TRIGger:B:LOWerthreshold:CH<x> This command speciﬁes the B trigger lower threshold for the channel selected

TRIGger:B:LOWerthreshold:D<x> Sets or queries the B trigger lower threshold for the digital channel selected

TRIGger:B:STATE Returns the current state of the B trigger

TRIGger:B:TIMe This command speciﬁes the B trigger delay time

TRIGger:B:TYPe This command speciﬁes the type of B trigger

TRIGger:EXTernal? Returns all external trigger-related parameters for the probe connected to the

Aux Input connector.

TRIGger:EXTernal:PRObe This command speciﬁes the attenuation factor value of the probe connected

to the A ux Input connector.

TRIGger:EXTernal:YUNIts? Returns the external trigger vertical (Y) units value

TRIGger:FREQuency? Returns the trigger frequency in hertz, if available

TRIGger:STATE? Returns the current state of the triggering system

Vertical Command Group

Use the commands in the Vertical Command Group to control the vertical setupof

all live (channel) waveforms for acquisition and display of channel, reference,

and math waveforms.

Use the command CH<x>:YUNits to set the vertical units for each channel. The

vertical units affect the “Probe Type” that is shown in the “Probe Setup” menu:

Setting CH<x>:YUNits to “V” causes the probe type to be displayed as

“Voltage”.

When CH1:AMSVIAVOLTs:ENAble is set to OFF, setting CH<x>:YUNits to

“A” causes the probe type to be displayed as “Current”.

Setting CH<x>:YUNits to anything else causes the probe type not to be

displayed (neither “Voltage” nor “Current” are highlighted).
