PCI-6351 Analog Input

[ericmsmith55]

I am looking to run multiple channels into the single-ended analog inputs of the PCI-6351 device. Does the device measure each pin sequentially or in parallel? I need to read multiple channels at the exact same time. Also, can the gain on each channel be set to different values, or is the gain the same across all of the channels?

Hi. Can you clarify your question?

[ericmsmith55]

Do the analog inputs read the input independently (at the same time) or do they run on the same clock where pin 0 is read before pin 1?

The PCI 6351 is a multiplexed card, so the inputs will be read sequentially.

I strongly recommend to have a look at the specifications... Figure 1!  Make shure you have low impedance sources or additional buffer amplifier. If possible change to a synchronious sampling card.

For a given samplerate/setup  the interchannel delays can be calculated/measured and corrected if a FRF needs to be measured.
