E-series GPCTR gate is faster than source

I'm using an E-series 6024 GPCTR to time a semiperiod measurements of a signal. I have two timers cascaded together gether because I need the 20Mhz speed as well as the ability to time up to really slow speeds. The problem occurs when have a pulse that is long enough to roll over to the second timer, followed by one that isn't long enough. The second timer does not reset to 0. I know there's function, ND_COUNTING_SYNCHRONOUS, but that's only for NI-TIO-based devices. What instructions/work-arounds exist for my device?

Hello;

There isn't a workaround for you to use the E-series DAQ device on that sort of application.
The only way to go is to use one of the 660x boards.
