Using NI 5911 with multiple triggers

[raeletro]

Is it possible to use the NI5911 to receive multiple triggers ? In my application there is an external device that generates trigger pulses at every start scan period. I would like to use the board to wait for 32 triggers. After each trigger the board must acquire N scans @ scan rate previusly defined. The Operational System CANNOT interfier on the process. Any help ?

Can we use it on linux ?

Hello,

The 5911 can run in a multiple record mode which allows you to tell the 5911 ahead of time that you want to do a certain amount of acquisitions (32 in your case) and to re-arm (start the next acquisition) in hardware without software interaction. This allows for a very small dead time (time between acquistions). There are multiple record examples that ship with NI-Scope in all environments and more information on this mode is available in the the software users manual that should be installed on your computer. If you cannot find it, here is a link to it on NIs website: http://digital.ni.com/manuals.nsf/websearch/91C5DEA19ACC6F2586256A8F0072E86F?OpenDocument&node=132100_US

Currently there is no support for the NI 5911 on Linux.
