:TRIG:ALT:TSCAL? SOURB Return 1.000e-003.
5. :TRIGger:ALTernation:TimeOFFSet
Command Format:
:TRIGger:ALTernation:TimeOFFSet <value>[,<source>]
:TRIGger:ALTernation:TimeOFFSet? [<source>]
Function:
The command sets the timebase offset.
In NORMAL mode, <value>: 1s ~ memory capacitance;
In STOP mode, <value: -500s ~ +500s.
Returned Format:
The query returns the value of timebase offset, and the unit is s.
Example:
:TRIG:ALT:TOFFS 0.0002,SOURB Set the timebase offset as 200μs.
:TRIG:ALT:TOFFS? SOURB
Return 2.000e-004.
6. :TRIGger:ALTernation:LEVel
Command Format:
:TRIGger:ALTernation:LEVel <value>[,<source>]
:TRIGger:ALTernation:LEVel? [<source>]
Function:
The command sets the trigger level of current channel. The <value> range
<value> range: (- 6*Scale-Offset
①
) ~(+6*Scale+Offset
①
).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: Trigger Level range is up to+/-6 Scale, when channel has offset, it needs to detract
offset ,such as 1V tap position, 1V offset, the trigger range is -7V~5V.
Returned Format:
The query returns the value of trigger voltage level, and the unit is V.
