The Spectracom 8140VT-46-45 is a GPS-based time and frequency synchronization device that delivers precise timing references for enterprise and laboratory applications. It acquires timing from GPS signals and generates multiple outputs including 1PPS and 10 MHz frequency references, supporting distributed synchronization across networked systems and test environments. The unit draws less than 150 mA and operates as a 3 Line Tap load in standard configuration, or 5 Line Taps with Option 45 installed.
Technical Specifications
• Synchronization Source: Global Positioning System (GPS) signals
• Timing Outputs: 1PPS (one pulse per second) and 10 MHz frequency reference
• Current Draw: Less than 150 mA maximum
• Load Configuration (Standard): 3 Line Tap equivalents; Option 45 increases to 5 Line Tap loads
• Internal Oscillator: Supports TCXO, OCXO, and Rubidium options for holdover operation when GPS is unavailable
• GPS Antenna Connector: Type N (powers active antenna)
• Output Connectors: BNC connectors for frequency and 1PPS outputs
• Dimensions: 5.25L × 2.63W × 1.71H inches (133L × 67W × 43H mm)
• Mounting Hole Pattern: 4.75 × 1.75 inches (121 × 44 mm)
– Key Features
• Provides 1PPS and 10 MHz frequency synchronization from GPS
• Operates standalone with Option 40 (single Line Tap equivalent load; required for outputs below 100 kHz)
• Low current consumption under 150 mA
• Option 45 available for increased load capacity to 5 Line Taps
• Compact MultiTap form factor with standard mounting hole pattern
– Typical Applications
Network time synchronization, laboratory frequency reference, distributed timing systems requiring GPS-disciplined accuracy, and systems where holdover capability via internal oscillator is essential.
– Compatibility & Integration
Works with Distribution Amplifiers as a 3 Line Tap device; standalone operation requires Option 40. Option 45 increases electrical load to 5 Line Taps when higher current distribution is needed.
