Portable GNSS GPS Disciplined Oscillator with Time Stamp to 100 ns Resolution with OCXO Holdover NT9400

Description

Portable 10 MHz Frequency Reference, NTP/NMEA Simulator with OCXO/Rubidium Holdover, 100 ns Time Stamp with Internet Alert

Bring Precision Timing Where it is Needed- 10 MHz, NTP

NT9400

A feature-rich portable reference platform that offers 1PPS and time server functionality with differential time stamping to 100 ns resolution. With a GNSS GPS disciplined timing source, time stamping accuracy within hundreds of nanoseconds.

This unit is built into a rugged, weather resistant injection molded case with critical electronics shock-isolated from the case. Battery capacity supports in excess of eight hours of operation or can be externally powered with 12 Vdc or included AC power adapter. An OCXO source is the primary reference that is locked to the GNSS with a high sensitivity 26 channel receiver. Rubidium holdover provides holdover < 15 usec/24 hr.

Built-in GNSS antenna simplifies use although an external GNSS antenna is supported. While the GNSS is active, the OCXO source is continually being disciplined to the GNSS GPS. In a GPS loss state, the PPS and 10MHz are slaved to the OCXO or Rubidium.  The PPS monitor allows an external PPS to be monitored and alert sent when a pre-defined limit is exceeded.
