Feature:
1. [Precise Control] Using 1PPS signal from GPS, the microcontroller compares it and outputs a 16Bit PWM to control the output accuracy of the constant temperature crystal, the frequency adjustment voltage of the constant temperature crystal is 0 to 5V, then a 1Bit PWM can control the output voltage to be 0.000076V.
2. [Versatile Applications] This GPS disciplined oscillator is suitable for high end audio decoders, instruments, frequency meters, signal sources, and any device with an external 10MHz reference input.
3. [User Friendly Design] Equipped with a display screen and an encoder on the front panel, this GPS disciplined clock provides real time status and easy setting adjustments.
4. [Comprehensive Connectivity] The back panel features 10MHz output interface, 1PPS output interface, GPS antenna interface, power switch, and 12V DC power supply interface, allowing seamless integration and operation.
5. [Compact and Portable] Despite its advanced functionality, this GPSDO maintains a small and portable size, making it easy to transport and use in various settings.

How to Use:
When turned on, the screen displays 10.00MHz GPSDO, and if a GPS antenna is not installed, this content will continue to be displayed. After installing the GPS antenna and locking the satellite, the screen will display the PPb correction value and the current PWM adjustment value after comparing the 1PPS signal.When used for the first time, it takes about 30 minutes to proofread and correct. When the PPb value is observed to be 0.0±1, press the encoding switch to enter the menu, rotate the encoder to find the PWMSET option, and press the encoder switch to save the current PWM value.Rotate the encoder again, find EXIT!! OK and press the encoder switch to exit the menu. At this point, the calibration is basically completed.After calibrating and saving the PWM values, the GPS antenna can be omitted for next use.
