Re : Two-Signal Edge-Separation Measuremen and input

[Fazi]

I am using that mode and the second signal coms from comparator max941.  Could you tell me if I need there a pull-up resistor to conect it to the  gate of the timer? Becouse it looks like the timer doesn,t see the edges.

We need more details from your pb to help you : connections, card, soft ...

NI 6221 PCI with SCB68 and LabView 8.0 . The output of the MAX941 Iis connected to the gate of timer1.  The timer is working in Two-Signal Edge-Separation Measuremen mode.

Hi Fazi,

You should be able to connect two TTL compatible signals to the gate and auxillary lines and measure the time between the two pulses.  Take a look at the article found here for more explanation on how you can use this type of task.  Do you have something connected to the to the Aux_line and source?  Are you using an external clock for the source? 

I hope this helps,
