immediate property 

immediate: TriggerSequenceImmediate

Return the TRIGger:SEQuence:IMMediate command.

Description
  • This command forces a trigger event to occur.
Usage
  • Using the .write() method will send the TRIGger:SEQuence:IMMediate command.
SCPI Syntax 
- TRIGger:SEQuence:IMMediate

slope property 

slope: TriggerSequenceSlope

Return the TRIGger:SEQuence:SLOPe command.

Description
  • This command sets or queries the slope of trigger signal.
Usage
  • Using the .query() method will send the TRIGger:SEQuence:SLOPe? query.
  • Using the .verify(value) method will send the TRIGger:SEQuence:SLOPe? query and raise an AssertionError if the returned value does not match value.
  • Using the .write(value) method will send the TRIGger:SEQuence:SLOPe value command.
SCPI Syntax 
- TRIGger:SEQuence:SLOPe {POSitive|NEGative}
- TRIGger:SEQuence:SLOPe?
Info
  • POSitive indicates that the event occurs on the rising edge of the external trigger signal.
  • NEGative indicates that the event occurs on the falling edge of the external trigger signal.

source property 

source: TriggerSequenceSource

Return the TRIGger:SEQuence:SOURce command.

Description
  • This command sets or queries the trigger source for an external trigger signal.
Usage
  • Using the .query() method will send the TRIGger:SEQuence:SOURce? query.
  • Using the .verify(value) method will send the TRIGger:SEQuence:SOURce? query and raise an AssertionError if the returned value does not match value.

Info
  • TIMer specifies an internal clock as the trigger source.
  • EXTernal specifies an external trigger input as the trigger source.

timer property 

timer: TriggerSequenceTimer

Return the TRIGger:SEQuence:TIMer command.

Description
