Timing & Frequency

Brandywine FTSU-100 Time and Frequency Distribution and Transfer Switch
Product Overview
  • Frequency and time outputs
  • Low phase noise frequency output
  • 1PPS output
  • Hitless fequency switching


The FTSU-100 is a high performance signal distribution amplifier designed for use with the Brandywine model PTS Precision Time System. Available in 1U and 2U sizes, both versions have hitless switching and very low phase noise outputs.
