2-72

The range of <value> is -6*Scale ~ +6*Scale. “Scale” indicates the current

vertical scale. The default unit is V/div.

Query Format:

:TRIGger:ALTernation:SLOPe:LEVelB?

Returned Format:

Query returns the set value of <value> in scientific numeric notation.

Example:

:TRIGGER:ALTERNATION:SLOPE:LEVELB□-1.5

Set Level B to -1.5.

:TRIGGER:ALTERNATION:SLOPE:LEVEL?

Query returns -1.500e+00.

Note: Minimum of Level A couldn’t be less than maximum of Level B.

6.15 :TRIGger:ALTernation<mode>:COUPling

Command Format:

:TRIGger:ALTernation<mode>:COUPling□{DC|AC|HF|LF}

Explanation:

The command is to set the coupling mode to be “DC”, “AC”, „HF” or “LF”. The

options of <mode> are “:EDGE”, ”:PULSe” or “:SLOPe”.

DC: Allow all signals pass

AC: Block DC signals and attenuate AC signals lower than 10Hz

HF: Reject high frequency signals (Higher than 150 KHz)

LF: Reject DC and low frequency signals (Lower than 8K Hz)

Query Format:

:TRIGger<mode>:COUPling?

Returned Format:

Query returns “DC”, “AC”, „HF” or “LF”. The double quotes are not returned.

Example:

:TRIGger:ALTernation:EDGE:COUPling□DC
