Brandywine TimeSpy - precise measurement tool for a wide range of signals

Brandywine TimeSpy - precise measurement tool for a wide range of signals

Product Overview:

  • Graphical display of the difference between input time signal and UTC
  • Capable of measuring a wide variety of classic and network time signal inputs
  • Timing resolution of better than 1ns and absolute accuracy of up to 30ns to UTC
  • Automatic identification and analysis of Modulated Carrier Timecode
  • ​Laboratory standard 1pps & 10MHz inputs can be used as a time reference
  • Frequency measurement range 40MHz to 50MHz
  • GOOSE and Sampled Values measurement capability for IEC61850
  • Full color touch-screen with user-friendly Window operating system
  • Front panel USB port for easy access downloads for subsequent data analysis
  • Robust, portable design for all industrial applications
  • Choice of time reference performance accuracy



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.

A precise measurement tool for a wide range of signals, such as NTP, IRIG B, 1PPS, ASCII against an internal precision GPS-controlled oscillator.
