ATS9462 User Manual
Triggered Streaming AutoDMA buffers do not include
headers, so it is not possible to get trigger time-stamps.
A BUFFER_OVERFLOW flag is asserted if the Data FIFO
overflows.
As in Continuous mode, the amount of data to be captured is
controlled by counting the number of buffers acquired.
Acquisition is stopped by an AbortCapture command.
Triggered Streaming AutoDMA can easily acquire data to PC
host memory at sustained rates up to 720 MB/s without
causing an overflow. This is the recommended mode for RF
signal recording that has to be started at a specific time, e.g.
based on a GPS pulse.
Stream To Disk
Any one of the AutoDMA modes can be combined with a fast
disk drive to create a very efficient and low cost data
streaming system.
AlazarDSO Stream To Disk module (sold separately) allows
out-of-the-box disk streaming. No programming is required.
Files are saved as ATB format binary files.
For more information on complete disk streaming systems,
please contact the factory or your local distributor.
