5.6.5 Zero Span Trigger Delay Compensation (External Trigger )
Under normal circumstances, after the trigger is generated, the displayed data and the data at the
same time as the trigger are displayed, but because the processing time of the trigger path and the
data path are different, the data displayed at the trigger time is the previous data. This does not
affect the integrity of the data and will not cause data loss at the trigger point. However, in some
cases, it is necessary to display the zero point of the screen coordinates as the input signal
information of the trigger point. At this time, the function of zero-span trigger delay compensation is
required.
5.6.6 Period(Period)
Set the trigger period.
Command format :TRIGger:FRAMe:PERiod
:TRIGger:FRAMe:PERiod?
Instructions Set/Query Period Trigger period
Parameter type Float
Parameter Range 100ns~10s
Return Float
Example :TRIGger:FRAMe:PERiod 1s
5.6.7 Offset Time(Period)
Adjusts the cumulative offset between the periodic trigger clock and the trigger event. The periodic
trigger clock cannot be seen on the software, only the trigger event can be seen. So if you want to
adjust the time of the trigger event, you can only adjust the offset between the periodic trigger
clock and the trigger event, but the absolute value of the internal offset is unknown, and each
modification to the offset is based on the previous Do accumulation.
Command format :TRIGger:FRAMe:OFFSet
:TRIGger:FRAMe:OFFSet?
Instructions Set/Query Period Trigger period offset
Parameter type Float
Parameter Range 0s~10s
Return Float
Example :TRIGger:FRAMe:OFFSet 1s
