- TB-1 Field Time Sync Generator
The TB-1 is a portable Field Time Sync Generator developed by Furuno. Featuring a built-in high-precision OCXO and GNSS receiver, it outputs 1PPS and 10 MHz reference frequencies synchronized with UTC. Its compact and lightweight design makes it an ideal portable time base for RF system maintenance, field measurements, R&D testing, and any application requiring a precise mobile timing reference.
• Field Measurements: Time synchronization and frequency measurement for 5G, V2X, digital broadcasting, and RF systems.
• Mobile UTC Sync: Reliable UTC synchronization for mobile base stations, remote equipment, experimental vehicles, and multi-sensor systems.
• Reference Source: Provides high-accuracy 1PPS and 10 MHz references for test instruments and both laboratory and outdoor measurement equipment.
• Handheld Design: A palm-sized solution that integrates easily with existing instruments, eliminating the need to carry bulky atomic clocks.
• Rapid Deployment: Outputs UTC-synchronized 1PPS and coherent 10 MHz reference frequencies within approximately 5 minutes.
• DSS (Dynamic Satellite Selection™): Intelligent selection of high-quality satellite signals to minimize multipath interference.
• High Reliability: Built-in multipath mitigation, anti-jamming, anti-spoofing, and holdover capabilities ensure stable performance in urban canyons, near windows, or GNSS-constrained environments.
• System Management: Supports Windows and Android monitoring software for real-time GNSS status checks and configuration management.
• On-board oscillator: OCXO
