I'm not sure you did.
The E4P electronics are good up to 10000 RPM for the 360 CPR model. That's what I was referring to in my previous post.

We plan to use encoders on 4.67/1 CimpleBoxes with CIMs. Max output rpm would be in the 1137 range.

As for the Jag, it can handle 1 million transitions per second (Joe's post). That's 1μs per transition.
For the E4P 360 CPR, there are 720 transitions per rev on each channel.
That's 1440 transitions per rev if you are using both channels.
The attachment shows the μs per transition for single-channel and 2-channel (quadrature) at 1137 RPM for the tolerances specified in the E4P datasheet.
The worst case (2 channel quadrature with max phase error) is 12.2 μs
So it appears that the Jag's sample rate is more than adequate to sample all transitions of an E4P 360 at 1137 RPM, even at worst-case phase tolerance with 2 channels in quadrature.
