Product Information
- 2024 New Upgrade: This GPSDO, compared to a regular timebase, can quickly locate problems. It has higher accuracy, lower temperature drift, and more stable output
- Accurate & Fast: It uses the GPS 1PPS signal, compares it with the microcontroller, and outputs a 16-bit PWM signal to control the output accuracy of the temperature-compensated crystal. The voltage for fine-tuning the frequency of the temperature-compensated crystal is 0-5V. Therefore, 1 bit of PWM can control the output voltage to be 0.000076V
- High-precision: Output frequency: 10.000000.000MHz ±0.001Hz; Supply voltage: DC12V ±2V; Working current: 350mA; 650mA(preheating); Output waveform: square wave; Output amplitude: -45dBm; Thermostatic crystal: ISOTEMP OCXO 143-141(disassembly); GPS module: NEO-6M
- How to Calibrate: When powered on,the screen displays "10.00MHz GPSDO". If there is no GPS antenna installed, this content will continue to be displayed. Once the GPS antenna is installed and satellite locked, the screen will display the correction value of PPb after comparing with the 1PPS signal and the current PWM adjustment value. It takes about 30 minutes for the initial calibration
- When the PPb value is observed within 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 encoder again and 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 value, it is not necessary to install the GPS antenna for subsequent use
- Portable & Widely used: The GPSDO is a highly portable device that can be taken anywhere for various needs, thanks to its compact dimensions of 5.9 * 3.5 * 1.5 inch. GPSDO is suitable for high-end audio decoders, frequency meters, signal generators and other devices with external 10MHz reference source input
