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
