The JI-820 is a flexible, easy-to-use, PC controlled instrument designed to precisely emulate the
function of a wide variety of incremental encoders. It provides the design, system, and test engineer
with a tool to accurately emulate encoder signals generated by motion control and industrial
monitoring systems. Variable encoder parameter available to the user include cycles per revolution,
cycle frequency, A/B signal phase, Z signal position and polarity, signal amplitude, and selectable
signal interface. An intuitive Windows application manages instrument setup and control.
Communications and unit power is all provided via a USB 2.0 link.
