COPulse interfere with Ai

[OresteMadia]

Dear all,

I'm using a DAQ-M to read a send a pulse to a lamp (ctr1) and, triggered by this same pulse, measure a voltage (RSE mode ai3).

However, the port PFI13 and the analog input are internally wired.

This means that the pulse interfere with my voltage measurement, as the voltage get divided as an effect of the low resistance path between the ai line and the control PFI line.

Is there any way I can de-couple these two lines ?

Can internally wired routes be interrupted ?

Thank you for your help.

Best regards,

Oreste

Depending on the board you use you can use routing to specify which output PFI you should use for the CO pulse and then you will not have interference between AIO and CO.
