Do they define it as

  • rising and falling edges per rev on one channel?

  • rising and falling edges per rev on both channels?

Couldn't find the term defined unambigously anywhere on the website or in the product datasheet.


Note: US Digital rates their encoders according to CPR, which they define as "Cycles Per Revolution", which is unambiguous. For example, a US Digital 360 CPR encoder would mean 360 cycles per rev, which is the same as:

360 rising edges per rev per channel
720 rising and falling edges per rev per channel
1440 rising and falling edges per rev both channels




Good question sir, I'm not sure yet. I plan to test that tomorrow and I will let you know.
