6002 6224 counter output event pulse width

Dear friends,

 

I will like to know the exact width in ms. of the counter output event pulse in a 6624 and in a 6602.

 

Also I would like to know if the width of these pulses is constant or it may change.

 

Best regards

 

Alberto

Hi Alberto,

 

I don't have one of these cards handy to test out at the moment, but I put together a VI that should be able to measure this (for timebases slower than the maximum anyway):

On my X Series the pulse width is equal to one full period of the timebase (e.g. using the 20 MHz timebase the output event is 50 ns, using the 100 kHz timebase the output event is 10 us).  I *think* the 6602 and 6624 should behave the same way but you'll probably want to verify.

 

This is assuming that the output behavior is configured as "Pulse" mode.  There is also a "Toggle" mode in which the output event toggles the state of the line until another output event is issued.

 

 

Best Regards,

John Passiak
