I have a PXIe 1082 with 4 DMM cards 4081 and 1 analogue card 6361. I perform some measurements with the DMM cards.
The 4 DMM cards are synchronise owing to the PXI trigger line 0.
The sampling frequency is around 100Hz but this value depends of my card initialisation (aperture time, average, autozero,....).
I would like to synchronise the analogue card with the DMM. Do you have some suggestion?
Thanks for your idea
There is no easy way to synchronize an USB and PXIe card as they don't share any buses.
You can use a timing card in your PXIe chassis to export the backplane trigger and wire it to the PFI input of you USB-6361.
Here is a link explaining how the timing card works: https://www.ni.com/hu-hu/support/documentation/supplemental/18/using-pxi-timing-and-triggering-funct...
Thanks for your help.
My analogue card is not a usb version it's a PXIe card too. The DMMs and the 6361 share the same PXIe backplane.
