1. GPSDO (Global Positioning System Disciplined Oscillator), also known as a GPS-disciplined oven-controlled crystal oscillator, GPS-disciplined clock, or 10MHz standard signal source. Compared to conventional time bases, it boasts superior precision, minimal temperature drift, and unparalleled output stability. 2. Leveraging the precise 1PPS signal from GPS, our microcontroller meticulously adjusts and outputs a 16-Bit PWM signal to meticulously control the oven-controlled crystal oscillator's precision. The fine-tuning voltage for the crystal oscillator ranges from 0-5V, where each 1Bit PWM increment precisely adjusts the output voltage by 0.000076V. 3. The front panel integrates a display screen and an encoder for easy operation. The rear panel is equipped with a 10MHz output interface, a 1PPS output interface, a GPS antenna connector, along with power switch and a 12V DC power input jack. 4. Ideal Applications: The GPSDO is perfect for high-end audio decoders, instruments, meters, frequency counters, signal generators, and any device requiring an external 10MHz reference source input. 5. It can provide these devices with a stable and reliable 10MHz reference source input to the accuracy and reliability of the equipment operation.
