(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
(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.
