The slim SRO-100 is a compact, cost-effective GPS/GNSS-disciplined rubidium oscillator (GPSDO) integrating advanced synchronization functions using patented SmarTiming+® technology. It precisely disciplines primary references such as GPS, Cesium, Hydrogen Maser, or T1/E1 with 1ns resolution.
Key features include:
- Output frequencies: standard 10 MHz; optional 5 or 15 MHz
- Accuracy at shipment: typically better than 5×10⁻¹¹ at 25°C
- Temperature range: standard -20°C to 60°C; extended options -30°C to 65°C
- Aging stability: less than 5×10⁻¹¹ per month standard; better with options
- Phase noise at 10 MHz: from -75 dBc/Hz at 1 Hz offset to -145 dBc/Hz at 10 kHz
- Holdover performance: under 1µs drift per 24 hours in typical conditions
- Warm-up time: approximately 12 minutes at 25°C for standard, faster with options
- Power consumption: between 7W and 50W depending on configuration
- Size: compact 101.6 × 70.61 × 25.4 mm (4 × 2.78 × 1 inches)
- Weight: lightweight at 234 grams (0.51 lbs)
- Designed for demanding timing applications, the SRO-100 delivers high stability, low phase noise, and reliable holdover in a small form factor.
