The TimeSpy precisely measures the time accuracy of a wide range of inputs (such as: NTP, IRIG B, 1PPS, and ASCII) against an internal precision GPS-controlled oscillator, displayed on the large, full color windows-based touch screen. The TimeSpy can precisely measure the time error at the point of use for systems where time is distributed over large distances. The TimeSpy can also measure free-running clocks and timing systems which are synchronized from untraceable sources, such as television and radio broadcasts, electrical power lines and the internet.
