PCIe-6321 maximum output rate

[sanctus]

Hello everyone,

I have a question regarding the NI PCIe6321 board. Currently, I am able to output signals using Python, but only at a frequency of up to 300 Hz. I am wondering if it's possible to output signals at a higher frequency, specifically more than 360 kHz, using these boards.

Thank you.

sure, it is possible as the hardware supports up to 900kS/s. Probably you're doing something wrong in your Python code limiting your output rate. BTW, you should be writing a chunk of points and not single point at a time.

You need to use sample clock timing and write multiple data points per write API call. See nidaqmx-python/ao_voltage_hw_timed.py
