filter in driver excel

Post by student »

Hello
I use the macro excel for adc 42 and then i calculate the FFT.
My problem is that i would like to filter before the acquisition.
We can change TIME and number of points (and then frequency)
Is it possible to activate a filter (with cut f/2) ????
Thanks
Pierre

Hi,

When using the ADC-42 functions there is not a funtion that will allow filtering. The adc-42 does not have and high or low pass filters, any filtering would have to be done by you in software (excel macro).

Hi,

I am sorry to hear that I did not give you a correct answer to your first post.

The ADC-42 does not have any Low or High Pass filtering on board, to achive this you would have to make your own, and put it between the ADC-42 and your signal.
