PXI Watchdog

[gtg811q]

I'd like some information on the PXI-8108 watchdog. Namely, is it an independent piece of hardware? If so what can it do if it trips? Also, is there any undervoltage lockout capability on the PXI-8108?

Hi gtg811q-

     The purpose of the Watchdog Timer is to provide software-independent means of recovery upon failure of a system or device. The Watchdog Timer is comprised of a binary counter and control registers that assert fixed control signals, upon timeout of the counter.  Here is another KnowledgeBase article that discusses what a watchdog timer does.

     In terms of undervoltage lockout capability, I think what you are asking is whether or not the 8108 will shut down if the power supply is below spec?  If so, then yes, the 8108 will shut down without proper minimum voltage.

     I hope this helps.  Best of luck with your application!
