For example, :TRIGger: SWEep SINGle /*Select single trigger mode*/ :TRIGger: SWEep? /*The query returns SING*/ :TRIGger:HOLDoff For example, :TRIGger:HOLDoff 0.0000002 /*Set trigger holdoff time to 200ns*/ :TRIGger:HOLDoff? /*The query returns 2.000000e-07*/ :TRIGger:POSition? 0 For example, :TRIGger:POSition? /*The query returns 100*/ :TRIGger:EDGe :TRIGger:EDGe:SOURce 68 / 136 Return format The query returns AUTO, NORM, or SING. Command format :TRIGger:HOLDoff :TRIGger:HOLDoff? Function description Set or query the holdoff time. The default unit is s.
Parameter Name Type Range Default Integer 8ns to 10s 8ns Description Trigger holdoff can stably trigger complex waveforms (such as pulse series). Holdoff time is the time the oscilloscope waits to re-enable the trigger circuit. The oscilloscope will not trigger until the holdoff time is over. When the trigger method is video trigger, timeout trigger, setup hold, UART, LIN, CAN, IIC or SPI, this setting is not available. Return format The query returns the trigger holdoff time in scientific notation. Command format :TRIGger:POSition? Function description Query the corresponding position of the waveform trigger position in the memory. Return format The query returns an integer.
A return of -2 means that it is not triggered, that is, there is no trigger position at this time. Returning -1 means triggering outside the memory, that is, the memory data cannot be read from the trigger position at this time. An integer value greater than 0 indicates that the return value is the corresponding position of the trigger position in memory. Command format :TRIGger:EDGe:SOURce :TRIGger:EDGe:SOURce? Function description Set or query the trigger source for edge trigger. Parameter Nam e Type Range Default Discrete {D10|D11|D12|D13|D20|D21|D22|D23|D30| D31|D32|D33|D40|D41|D42|D43| CHANnel1
