Frequency sweep using an AT-MIO-16E-10

[only1bit]

Hello to all! How it is possible to carry out a frequency sweep until 20k using LabView, an AT-MIO-16e-10 and circular buffer mode? Thanks for the aid.

Hello;

I'm attaching a Labview example that shows how to create data points of a Frequency sweep type. The attached VI routes the generated data to a sound card, however, you can replace the sound VIs by the Analog Output VIs. I suggest you to grab one of the Labview shippiong examples that shows how to do Analog Output operations, and combine both VIs to accomplish what you need.

Hope this helps.

Hello Filipe A.,
thank you for the aid, but my problem is not the sweep.
My problem is the DAQ board that not go up in frequency (over 1kHz). It give me this error: -10843 underFlowError. DMA channels are configured but the board seems "system depended". I used "test panel" utility in MAX to verify the function of the board and I have the same error when I generate a sine of 10KHz.
Do you have any suggestion?

Thank you a lot for the aid.
