pulsewidth data logging with counter channel

[Nisarg]

Hello everyone.

i have query with data logging of pulse duration measured with counter input into .lvm file

pulse signal contain frequency of 100 hz with pulse duration vary from 2 to 8 ms

 i want to log pulse duration in .lvm file.

when running vi(below screen shot) i find data logg with duplicate instance of time.

i want to log pulse duration data with every ridging or falling edge of pulse.

so if i run vi for 20 sec i sould have 2000 reading of pulse duration in my.lvm file with appropriate time  in time column
