OCXO PPS Simulator

Category: NMEA PPS

PPS Source - OCXO with 1 Hz Frequency Synthesizer

NR3700-PPS

Ultra-stable OCXO drives a 1 Hz synthesizer to generate a 1 Hz CMOS signal. A one pulse per second signal when GPS is unavailable. 50 % duty cycle, 5 volt or 3.3 Vdc output waveform with a 200 ohm output impedance.  Standard OCXO with stability of 50 ppb/year- band – gap reference provides outstanding temperature stability < 10 ppb.

Unit can operate from an AC power adapter or DC powered from – 60 to +60 Vdc in one of three voltage ranges.

  • ±50 ppb/year aging ( options to 10 year projected of +-200 ppb)
  • 5 or 3.3 Vdc CMOS levels
  • Factory settable PPS duty cycle
  • 200 Ohm output impedance
  • Fault and transient protected
  • Band Gap reference enhances temperature stability
  • -60 to +60 Vdc operating input voltage (in three ranges)
  • Accuracy of +-10 ppb (after 24 hours)
  • Other Frequencies--1 Hz, 10 Hz, 100 Hz, 1 kHz, 100 kHz, 1 MHz, 10 MHz
