Product Description body { font-family: Arial, sans-serif; line-height: 1.6; } GPSDO (Global Positioning System Disciplined Oscillator) Also known as the GPS Tamed constant temperature crystal oscillator, GPS-tamed clock, and 10MHz standard signal source. A step above the general time base, this device offers higher accuracy, reduced temperature drift, and a stable output. Ideal for high-end audio decoders, instruments, meters, frequency meters, signal sources, and any device that requires an external 10MHz reference source input. Features Strong Durability: Crafted with precision, featuring a premium housing and top-quality electronic components. Ensures extended durability and long service life. High Accuracy & High Stability: Delivers superior accuracy over general time bases, with minimal temperature drift and consistent output. Voltage Adjustment: Utilizes a GPS 1PPS signal combined with microcontroller comparison for precision output control. The isothermal crystal frequency fine-tuning voltage ranges from 0 to 5V, with 1bit PWM controlling an output voltage of 0.000076V. Easy to Use & Multifunctional Interfaces: The front panel includes a display screen and encoder, while the back panel is equipped with a 10MHz output interface, 1PPS output interface, GPS antenna interface, power switch, and 12VDC power interface. Wide Applications: Perfect for a range of scenarios, including high-end audio decoders and a variety of scientific instruments and devices needing a 10MHz reference input.
