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.
