	The maximum rate of the PhidgetEncoder Highspeed 4-Input is specified at 250,000 quadrature cycles per second. Since this device counts pulses rather than cycles, you could also say that it counts a maximum of 1,000,000 pulses per second (since there are four pulses in a cycle). In your application, these numbers relate directly to the number of revolutions per second you wish to measure, and the number of counts per revolution specified for your encoder. If your encoder's wheel has 1000 counts per revolution, then the limit on measurable revolutions per second is 250, or 15,000rpm (which, for the 1047, corresponds to 1000 position changes in software per second).

			One of the most common problems encountered with connecting encoders to a 1047 is a strange "jitter" characterized by the encoder position appearing to switch back and forth between 0 and 1 or -1 and nothing else. This is usually indicative of a bad connection on either the A or B channel. You should check that the wiring is sound and try again.

	If the number of quadrature counts per revolution is unknown for a particular encoder, this value can be determined by using the index signal. In addition, it is possible to monitor how many counts have occurred since the last index. The index signal is an output only on certain encoders. Refer to the encoder’s description to check if this third output channel exists or not. If the encoder does not have this signal, it is still possible to use it with the PhidgetEncoder Highspeed 4-Input, but an event for the index will never get triggered.
