Overview

Built by Power Professionals, For Power Professionals Model 940A Timing System Analyzer is a comprehensive instrument for power substation timing. Intuitive and easy to use, the Model 940A is designed to simplify timing system installation and maintenance. Capable of measuring and sourcing IRIG-B, DCF77, and 1PPS timing signals, the Model 940A is a must have tool for substation timing systems. The Model 940A uses two identical input channels capable of measuring IRIG-B (unmodulated, modulated and modified manchester), DCF77 and 1 PPS timing signals. The timing signals are decoded and displayed as text and/or graphically showing the complete timing signal down to the IRIG-B bit level. The dual inputs allow for comparison to a calibrated signal or between different signal generators. The Model 940A Timing System Analyzer is also equipped with an output that can source modulated IRIG-B, unmodulated IRIG-B, 1 PPS and DCF77. Output levels, modulation ratios, and the timing reference are configurable. The flexibility to synchronize the timing reference to Input 1, Input 2, the internal Real Time Clock, or a user customized setting makes the 940A suitable to test any timing scenario.
