Programming Introduction RIGOL
Programming Guide for DS1000CA Series
Example:
:TRIG:ALT:SLOP:LEVB -1.5 Set Level B as -1.5V
:TRIG:ALT:SLOP:LEVB? Query returns -1.500e+00
15. :TRIGger:ALTernation<mode>:COUPling
Command Format:
:TRIGger:ALTernation<mode>:COUPling{DC|AC|HF|LF}
:TRIGger<mode>:COUPling?
Function Explanation:
The commands are used to set and query the coupling mode as “DC”, “AC”,
„HF” or “LF”.
DC: Allow all signals pass
AC: Block DC signals
HF: Reject high frequency signals (Higher than 150kHz)
LF: Reject DC and low frequency signals (Lower than 8kHz)
The options of <mode> are “:EDGE”, ”:PULSe” or “:SLOPe”.
Returned Format:
Query returns “DC”, “AC”, „HF” or “LF”.
Example:
:TRIG:ALT:EDGE:COUP DC Set the coupling condition as “DC”
:TRIG:ALT:EDGE:COUP? Query returns “DC”
16. :TRIGger:ALTernation<mode>:HOLDoff
Command Format:
:TRIGger:ALTernation<mode>:HOLDoff <count>
:TRIGger:ALTernation<mode>:HOLDoff?
Function Explanation:
The commands are used to set and query the trigger holdoff. The options of
<mode> are :EDGE, :PULSe, :SLOPe or :VIDEO. The range of <count> is
500ns~1.5s.
