Can I use the Inhibit switch on the PXIe-1075 chassis as an engineering control interlock for my test fixture??

Hi,

I am going to create a DIB for my bench test setup that needs to have a control interlock. Since the PXIe-4139 SMU can source more than 45V, my setup needs to have an interlock.

Can I use the Inhibit switch on the PXIe-1075 chassis as an engineering control interlock for my test fixture??

Will this disable the PXIe-4139 SMU's output?

Does the computer controlling the chassis need to be rebooted to get the chassis communication back up after the inhibit switch disables it?

Thanks for any suggestions.

Hey,

I wouldn't really reccomend shutting the chassis down to simply turn off an output. It seems like the best way would be to use a simple digital trigger to accomplish this instead.

That being said, I don't see a reason that this particular idea wouldn't work, although it seems like overkill. I haven't personally tested if turning off a chassis through the inhibit switch would cause all outputs to power off, but I do suspect it would.
