2-41

: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-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: 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.
