10 MHz Low Noise TCXO, GNSS Locked with Optional Synthesized Secondary Channel

The NR6720-CAL-T is a GPS/GNSS locked TCXO, 10 MHz frequency reference with PPS, RS232 and an optional secondary channel that can be programmed from 14 KHz to 10 MHz. The PPS option includes a PPS processior to reduce jitter and improve stability by almost 20 dB. The unit features Auto-Calibration so that the most recent coefficients to compensate the TCXO for drift due to aging and/or temperature are stored and applied to the TCXO during GPS/GNSS loss of lock conditions. The unit operates from a 12 VDC power source or available AC power adapter. High performance 26 channel GPS receiver that supports GPS, GLONASS, SBAS, QZSS. By being able to receive data from multiple satellite constellations, lower lock time is achieved. With twice the number of satellites in view, as a GPS only configuration, achieving and maintaining lock in poor signal environments is enhanced.  Good choice for general lab use.

  • Holdover stability of +-1 ppm/year

  • Locked accuracy <4E-11

  • Available -60 to +60 VDC in 3 ranges

  • Concurrent reception of GPS and GLONASS

  • PPS accuracy 20 ns rms

  • Secondary channel synthesized frequency range 14 KHz to 10 MHz (nominal is 10 MHz, 3.3 VDC CMOS)

  • Indicators and signals provide GPS/GNSS lock and unit self-test status
