5.6.2 Reference Trigger
User can configure a trigger condition and acquire the data between trigger asserted
in the Reference Trigger mode. Data acquired before trigger occurred is pretrigger
samples. Data acquired after trigger occurred is posttrigger samples. User can
configure two parameters, “PretriggerSamples” and “SamplesToAcquire” to capture
specified data as shown in Figure 31.
This trigger mode is only suitable for finite acquisition mode. The default number of
pretrigger samples is 0.
SampleToAcquire: 1000
PreTriggerSamples: 10
Posttrigger samples: 1000 - 10 = 990
Figure 31 Reference Trigger mode
5.6.3 Retrigger
User can configure a specified trigger condition and repeat trigger times to capture
signal. The number of repeat trigger times is set by the parameter “ReTriggerCount”.
For example, we set the ReTriggerCount to N and the length of each acquisition to M,
therefore the total acquired samples is N * M * channelcounts as shown in Figure 32.
Note, Retrigger mode is only valid in finite acquisition mode.
