Synchronized AO and Counter task with DAQmx base

[sugar7]

Hello,

I'd like to get some ideas to implement the synchronized AO and either gate counting or two edge separation.

My devices are PCI-6110 and 6602 connected with a RTSI cable.

What I want to do looks like the measurement shown in the link https://decibel.ni.com/content/docs/DOC-3882

and basically the AI in that vi is replaced with Counter input.

Is this feasible with my setup?

Thank you for your time.

best,

Hi sugar7,

I believe what you are trying to is entirely possible.  I have even found some examples that you can manipulate for your use:

DAQmx Base Synchronized Finite Analog Input Continuous Analog Output

Synchronized Analog Output on Multiple Devices (RTSI/PFI)

Let me know if you have any additional questions, thanks!

Hello,

Thank you for your reply.

If I need to generate gate pulses for gate counting or first and second edges for two edge separation,

should I send aostarttrigger and master timebase from PCI-6110 to 6602 through a RTSI cable and

use them for armed trigger of counters?

Also, in my application, what's the maximum transfer rate of the counted values?

The table2-1 of the 6602 manual shows rates for different buffer size.

I read some threads and found the buffer size of 6602 is only 2.

Does this mean the max rate in continuous operation is around 10 kS/s

and this is the max AO sample clock I can set?

Your kind support is highly appreciated.
