The WR-1011 Rubidium atomic frequency standard offers a 10 MHz output with high stability, low drift, low power consumption and multiple interface options.
The WR-1011 Rubidium atomic frequency standard provides a compact, low‑power solution for synchronization in optical networks, mobile and wired communications, power‑grid monitoring, broadcasting, and vibration‑prone environments such as ship, vehicle and aircraft installations. It features a standard 10 MHz output (5 MHz or 20 MHz optional), RS‑232 communication, and optional vibration‑reinforced construction.
Technical specifications include frequency stability down to 3×10⁻¹¹ / s, phase‑noise performance of –70 dBc/Hz at 1 Hz, a selectable power supply of +24 V (or +12 V optional), and a small form factor of 77 × 75.5 × 36.5 mm weighing less than 350 g. The device supports both digital and analog frequency adjustment methods and provides DB9 and SMA connectors for signal and control interfaces. This manual is written in Chinese.
