(6) :TRIGger:ALTernation:LEVel

Command Format:

:TRIGger:ALTernation:LEVel□<value>[,<source>]

Function:

The command sets the trigger level of current channel. The <value> range

<value> range: (- 6*Scale-Offset①) ~(+6*Scale+Offset①).Scale is the

current vertical scale, and the unit is V/div. the <source> may be SOURceA

or SOURceB, and the source A and B is different according to the current

alternation channel.

NOTE①: TtigLevel range is up to+/-6 Scale, when channel has offset, it needs to

detract offset ,such as 1V tap positon, 1V offset, the trigger range is -7V~5V.

Query Format:

:TRIGger:ALTernation:LEVel?□[<source>]

Return Format:

The query returns the value of trigger voltage level, and the unit is V.

Example:

:TRIGGER:ALTERNATION:LEVEL□2, SOURceB

Set the trigger voltage level as 2V.

:TRIGGER:ALTERNATION:LEVEL?□SOURceB Return 2.00e+00.

(7) :TRIGger:ALTernation:EDGE:SLOPe

Command Format:

:TRIGger:ALTernation:EDGE:SLOPe□<value>[,<source>]

Function:

The command sets the edge type of edge trigger in current channel as

POSitive (rising edge) or NEGative (falling edge). The <source> may be

SOURceA or SOURceB, and the source A and B are varying with the current

alternation channel.

Query Format:

:TRIGger:ALTernation:EDGE:SLOPe?□[<source>]

Return Format:

The query returns POSITIVE or NEGATIVE.
