Synchronization of multiple AI voltage channels by using X-6363 USB

[Hasham622x]

Hi,

I apologise for the disturbance. I am currently working on synchronizing multiple AI channels and will be using the X-6363 USB, where ai0 acts as the master channel and all other channels function as slaves.

I have downloaded the shipping example, which uses two sample clocks. However, I am uncertain about which sample clock source would be most appropriate for my setup—whether I should use the onboard clock or counters. Additionally, in the synchronization type option on the front panel, I noticed that it lists "X series (PXIe) < SC Express." Could you please guide whether this setup would also support the X-6363 USB?

For your reference, I have attached the LabVIEW code (LV19 version) to this message.

Thank you for your time and assistance.

Kind regards

That example is for synchronizing multiple devices. Are you using multiple devices? What is the model of another device, other than the USB-6363?

If you are using multi-channels inside a device, you can use Channel Expansion

Hi,

Thank you for your response. I will be using a single X-6363 USB device, and I intend to synchronise multiple AI channels by designating one channel as the master, with the others functioning as slave channels.

Once again, thank you for your assistance.

Kind regards

Hasham

Number of Parallel DAQmx Tasks on NI Multifunction Devices

You can have only one hardware-timed AI task per device. Hence you can only add all desired AI channels to the same task through channel expansion.
