TimeSpy Elite

Portable Network Time Analyser with Precision Time Measurement

TimeSpy Elite precisely measures the accuracy of a wide range of classic and network timing inputs against an internal precision GPS-controlled oscillator. It has enhanced features over the standard TimeSpy: it has Gigabit Ethernet capability plus an SFP connection for use with alternative media e.g. fibre. TimeSpy Elite also optionally accommodates a laboratory standard input to use as a time reference. 

  • Measures and displays the difference between input time signal and UTC
  • Capable of measuring a wide variety of classic and network time signal inputs, including PTP [IEEE 1588 v2] and Have Quick
  • Timing resolution of better than 1 nanosecond
  • SFP connection for connection to alternative media (module not supplied)
  • Gigabit Ethernet capability  
  • Absolute accuracy of up to 50 nanoseconds to UTC
  • Automatic identification and analysis of Modulated Carrier Timecodes
  • Full colour touch-screen with user-friendly Windows-based operating system
  • USB port on front panel for easy access downloads for subsequent analysis of data 
  • Robust, portable design for all industrial applications 
  • Input available for measurement of relay opening/closure
  • User-selectable threshold for alarm generation
  • Robust, portable design for all industrial applications
  • Choice of clock accuracy: see selector table overleaf

Input Time Signals:

1PPS, PP2S, 1PPM, 1PPH, Timecode DC level shift, ASCII serial RS232, RS422, RS485, NMEA plus Pulse, NTP to RFC 105, PTP (IEEE 1588 v2), DCF77, Have Quick


TimeSpy Elite is invaluable where time of day information is distributed from a central master clock to sub-master clocks or user systems over large distances via serial data links or packet networks.

Substantial delays can occur due to high levels of network traffic or even due to the long distance between the master clock and the user.

Some commercially available software algorithms can reduce these errors but, unless the errors are accurately and independently measured at the point of use, the user cannot be certain of the accuracy of his time source in this type of application.

Additionally, the high accuracy of the TimeSpy Elite means that it can also precisely measure the time error of free-running clocks and timing systems which are synchronised from untraceable sources, such as television and radio broadcasts, electrical power lines and via the internet.

Ease of Use

As the unit is portable and battery powered, it is simple to synchronise the unit to GPS outside by using the integral GPS antenna.

Alternatively, synchronisation can take place inside if connected to an external GPS antenna, with further flexibility to use AC mains power.
