Description
This command works in conjunction with the TRIGger:DELay command and
the SAMPle:TIMer command to determine sample timing when the sample
count is greater than one. In all cases, the first sample is taken one trigger
delay time after the trigger (the delay being set with the TRIGger:DELay
command). Beyond that, the timing mechanism depends on whether you
select IMMediate or TIMer as the source:
If you select SAMPle:SOURce IMMediate, the first sample starts one
trigger delay time after the trigger, and then the trigger delay time is
inserted between the first and second samples, the second and third,
and so forth:
Note that the sample timing is not deterministic because the delay time
(set with TRIGger:DELay) is inserted after each sample completes. The
actual time required to take each sample depends on the integration
time and autoranging time. In this case, the SAMPle:TIMer command
has no effect.
If you select SAMPle:SOURce TIMer, the first sample starts one trigger
delay time after the trigger. However, the second sample starts one
sample interval after the start of the first sample, and so forth:
Note that the sample timing is deterministic because the start of each
sample is determined by the sample interval, set with the SAMPle:TiMer
command (TRIGger:DELay affects only the start of the first sample).
Integration and autoranging affect the sampling time for each sample,
but not the sample interval as long as the sample interval is longer than
the sampling time.
It is recommended that all triggered measurements be made using
an appropriate fixed manual range. That is, turn autorange off
