1 PPS Monitoring, Frequency Stability Analysis, and Phase Noise Analysis Demonstrations at the International Timing and Sync Forum (ITSF) 2025

| 日期 03 December 2025

Swabian Instruments concluded a strong week at the International Timing and Sync Forum (ITSF) 2025 in Prague, with a poster presentation on “Timing and Frequency Measurements from Picosecond Time Tags.” On the exhibition floor, we demonstrated remote Time Tagger synchronization with picosecond-level precision and how time tags generated at distant locations can be merged in real-time for time-correlated measurements.

Timing and Frequency Key Conference Highlights at ITSF

Timing and Frequency Measurements - Scientific Poster Presentation

  • Swabian Instruments team presented a poster on “Timing and Frequency Measurements from Picosecond Time Tags,” showcasing how Time Taggers are used for remote synchronization and high-precision timing and frequency analysis experiments. With the Time Taggers’ versatile software toolkit, users can perform correlation measurements between remotely synchronized Time Taggers, monitor Pulse-Per-Second (1PPS) signals, and conduct frequency stability and phase noise analysis for clock characterization.

Engagement with the Timing and Frequency Community

  • Booth engagement was consistently high, with researchers and operators stopping by to discuss precision timing. A particular highlight of the week was Yulia Matiks winning NetTimeLogic’s ‘10-second challenge’ in which players press a button to start a timer and again to stop the timer as close to 10 seconds as possible. Yulia won with a 667 µs deviation, outperforming over 250 attempts, and demonstrating just how comfortable our scientists are with time precision!

PPS Monitoring, Frequency Stability Analysis, and Phase Noise Analysis Demonstrations

  • Operators and researchers need to diagnose timing issues quickly, across multiple sites, and without extra hardware. Software-defined analytics on precise time tags provide real-time visibility, reduce measurement hops, and enable scalable synchronization across lab benches, data centers, and field deployments.
  • Our team demonstrated continuous 1 PPS integrity monitoring across distributed nodes using remote Time Taggers with trend and statistic views.
  • Using multiple oscillators, we ran parallel frequency stability (including Allan Deviation ADEV and Time Deviation TDEV) as well as phase-noise analyses in our GUI Time Tagger Lab (also available in the APIs in MATLAB, Python, etc).

We look forward to next year’s conference and are grateful to all those who stopped by our booth. Interested in exploring how our Time Taggers might help accelerate your research? We’d love to hear from you. Email solutions@swabianinstruments.com
