Multipurpose NTP Time Server

TS-2335 is equipped with not only NTP output but also versatile time outputs and can synchronize the time for different kind of systems.


  • Oscillator stability: +/-10ms/day
  • Time source: GPS

Features of TS-2335

Features 1 Highly Accurate Time Synchronization

Besides a time distribution via NTP output, TS-2335 is equipped with time code outputs (IRIG, serial interface) and reference signal outputs (pulse output and frequency output).

Features 2 IRIG time code

TS-2335 can be either synchronized from a dedicated GPS receiver, from another NTP server or from IRIG time source.

Features 3 Redundant power

Completely redundant power supply with the combination of AC90-240 x DC 24V or DC24V x DC24V.

Features 4 Redundant NTP server operation

To avoid time deviation between two TS-2335, they can be linked via a fiber-optic connection by using optional two GBIC modules.
