Will the NI PXI-5422 generate a chirp waveform from 9.5 to 10.5 MHz?

[allen7]

Across a pulse width of 50 or 100usec with a PRI of 1msec upon the application of an external TTL trigger? Will this unit generate this user defined chirped waveform each time it receives an trigger? Also, the generator will need to stop playing out the chirped waveform at the end of each pulse and generate a 10MHz CW signal between pulses. And finaly, how long after the receipt of the trigger,will it take to get the output waveform? Oh yes, will the 80MHz sampling rate always be that for the generated wavefomr?

You can easily generate a user-defined triggered chirp pulse which meets the specs that you are requesting with the 5422. If you want a rough idea of the trigger latency on the 5422, you can look at the start trigger specs for the 5421 on page 21: http://digital.ni.com/manuals.nsf/websearch/D15FC16269E088F886256D66007ED513?OpenDocument&node=13210....

The difficult part would be outputing a continuous waveform in between the user-defined waveform, and the next trigger. You can view the different trigger modes for the 5422 in the user's m
anual. In summary, you can do stepped triggering, which limits you to outputing a single user-defined waveform with each trigger. The other option would be burst trigger mode, which would continuously output a different user-defined waveform each time a trigger occurs. Neither of these options would enable a single user defined pattern to be followed by a continuous pattern with a single trigger.

I hope this helps.
