RMS4185A-PPS GPS TIME SYNCHRONIZATION

For applications where better accuracy is desired, and/or where implementation of software for data re-arrangment at processing time represents a problem, or where simply it is desired to have all data structuring and time-tagging taken care of in real-time, we have implemented a scheme for synchronization of the data systems and AADCII Compensator to the 1-PPS signal from a GPS receiver, which uses the event input port in a modified version of the Analog Input Module, RMS4185A-PPS.
