10 Channel PPS Source with Rubidium Holdover, Multi-GNSS, and 10 MHz Reference

10 Channel 1PPS Source with Rubidium Holdover (NR2310D-PPS)

• Ten fault & transient-protected 1PPS outputs with < 1 ns channel skew (typically ~200 ps)
• 26-channel high-sensitivity Multi-GNSS receiver (GPS, GLONASS, QZSS, SBAS) with TRAIM and position modes
• UTC-synchronized 1PPS with accuracy better than 15 ns, ideal for precision timing
• Optional low-noise 10 MHz frequency reference output to stabilize local oscillators
• Rubidium holdover option keeps PPS drift < 0.5 µs/hour for GNSS denied or unstable GPS environments
• LVCMOS outputs: 3.3 V or 5 V into 50 Ω, available on SMA connectors or BNC connectors
• Front-panel status monitoring, built-in self-test, and alarm panel integration
• Rackmount modular chassis design with AC powered or DC powered options
• Eliminates the need for a distribution amplifier with ten robust outputs
• Supports advanced anti-jamming and multipath mitigation for reliable timing

The NR2310D-PPS is a reliable PPS source built for mission-critical timing applications. Its Multi-GNSS receiver provides redundancy across GPS, GLONASS, and QZSS, while the Rubidium holdover ensures stability in GNSS denied conditions. Engineers benefit from low-noise design, auto calibration, and flexible output options with SMA or BNC connectors. Perfect for labs, telecom, defense, power utilities, and financial systems requiring high-precision synchronization.

FAQ

1. What connectors are supported for output?
   The PPS outputs are available on SMA connectors or BNC connectors, supporting easy integration into existing infrastructure.
2. Can the unit maintain accuracy without GNSS?
   Yes. With the Rubidium holdover option, drift is held to < 0.5 µs/hour, maintaining stable 1PPS accuracy in GNSS denied environments.
3. Does this device replace a distribution amplifier?
   In many cases, yes. With ten transient-protected outputs, the NR2310D-PPS often eliminates the need for a separate distribution amplifier.
