Doubt about the sampling frequency when generating and acquiring

[hcobas]

when generating and acquiring samples, the maximum sample rate is the maximum board sample rate divided between the number of generating and acquiring task?

thanks

Hi hcobas,

- usually AI and AO tasks are separated, not interfering each other.

- max sample rate is determined by your hardware. Is it using a MUX? Does it support hardware timing? Hardware timing for all I/O channels?

Hello GerdW, thank you for your reply.

I am using the DAQPad6016 acquisition board which have a maximum sampling frequency of 200 kS/s. Initially i want to generate a excitation signal and acquire the response signal. So i am using an analog output for the waveform generation and analog input for the waveform aquisition. So in these terms i am not using the mux because as you said they are separated task.
so these means that i can generate and acquire to the maximum sampling frequency (200 kS/s) for each one of them?

thank once more time.
Best regards,
Houari

Hi Houari,

you should read the specs of your DAQpad more carefully!

It clearly says: Analog inputs = 200kS/s samplerate, but analog outputs = 300 S/s sample rate or just even 50S/s for hardware timing!

Thank you very much. I really did not perceive it. I see the hardware wil not work well enough.

Thank you very much, really
