Slow data acquisition in Excel

Post by G.H.Stephenson »

Hi, I have setup a DAC16 to run in an excell macro, using all 8 channels, and a userform full of graphs. But for some reason it takes 6 seconds to detect there has been a change by the inputs, and only seems to sample evry 2 seconds. Can you help me?
I can e-mail the program to you if it is any help
Thanks
Graham

Hi,

I would recommend that you use the function get_cycle, this will let you know when it has a converstion for each of the active channels.

If you are using filtering then this will also increase the amount of time to get a signal.

The ADC-16's sample rate is 1 sample every 1.5 seconds when running at 16 bits this can be sped up if the resolution is reduced.

Best regards,
