Real time response

Hi,

I'm Marc and I have the T7-PRO. I have been testing the T7-PRO with the purpose of testing in the automotive sector.
I'd like to know if exists any way or method for making a time log. I'll explain myself, I'm currently measuring the response of a change on the state of a signal, to do this I want to get the time that passed between the activation of a signal (ex. DIO) and the acquisition of the change.

As I'm using a standard O.S. Windows and using a Python interpreter, I got stucked in a minimum response time of around 200 milliseconds in both Ethernet and USB communication.

Could you give me some advice of how can I achieve less response time? I'd be fine if I get around a 100 ms. 

Thank you very much for your help.

Marc.
