Hardware to Measure 5µs TTL Rising Time

Hello,

I have a cRio 9074, with 1 NI9401 for cRio. I need to measure the rising time (10%~90%) of a TTL signal, this signal has a frequency of 2kHZ and an expected 5µs rising time.

My question is how can I, or if it is possible to measure  this rising time using an I/O module for cRio?

If is not possible to use an cRio system, which hardware from NI is capable of doing it? Preferably a NI PCIe Card.

Thanks in advance.
