3.4 Averager with triggered simultaneous acquisition and readout (AVG/TSR/INT option)
56
U5303A User's Manual
Performance
Excepted for small number of averages, the architecture enables no trigger loss. The maximum
performance of the system depends on the number of average and the trigger rate.
The minimum number of average is 8.
The maximum number of average records only depends on the record size and the size of the storage
device.
Output format
The readout of the averager records and output format are the same than with standard averager
mode.
Each AVG readout sequence illustrated on figure above, has a latency time (similar to "AVG
deadtime") before starting data readout. But there is no trigger lost during this time, contrary to
standard AVG mode.
Limited risk of overflow
There is a risk of overflow only with configurations using minimum number of averages, and very high
trigger rate.
If an overflow occurs, the writing is disabled, implying that follow-on triggers may be lost. A property
indicates that there is no more memory available to perform additional acquisitions. Abort function is
not yet supported in AVG +TSR mode. So in this case, memory can be cleared by closing and
reinitializing the card.
AVG/TSR Configuration
Regarding averager AVG function, the interfaces/methods/properties (functions/attributes) are
detailed in
