Re: Adjust CP4 Clock Frequency

Craig Young

How does the CP4 determine Sidreal Rate when using encoders?  For example, does the CP4 count encoder pulses over a given period of time?  Assuming the pulses represent an arc of the mount and knowing precisely the arc change per given time period it would seem this could be used to check the tracking rate.  Which would then imply a precise calibration of pulses per arc length.  How is that done?
