PWM/TPO measurement with EPIC

I have a potential project where the device sends a TPO signal at 45Hz to indicate an analog value. What is the best hardware and commands to use to measure the % on time of the signal?

Does the Get On-Pulse Measurement command work with EPIC? The PAC Control help in 10.5 under the “Dependencies” is not clear if it is available on EPIC.

With a GRV-IDC-24 module with a 1000Hz max module frequency, I assume the best resolution is 1ms on the measurement, which would give about 5% resolution of a 45Hz signal. If I need better resolution than that, will the GRV-IDCIFQ-12 module work with this command? With that module does the Pulse Measurement 100μs become the limiting resolution?
