Package included: GPSDO x1 GPS Antenna x1

?Widely Application?GPSDO is suitable for high-end audio decoders, frequency meters, signal sources and other devices with external 10MHz reference source input. ?Portable Size?The size of the GPSDO is 186*88*40mm. The front panel has a display screen and encoder, the back panel has a 10MHz output interface, 1PPS output interface, GPS antenna interface and power switch and 12V DC power interface. ?How to Calibrate?When powered on, the screen displays "10.00MHz GPSDO", which will always be displayed if no GPS antenna is installed at this time. When the GPS antenna is installed and the satellite is locked, the screen will display the PPb correction after comparing the 1PPS signal and the current PWM adjustment value. For the first time, it takes about 30 minutes to calibrate. When the PPb value is 0.0±1, press the encoding switch to enter the menu. Rotate the encoder to find the "PWMSET" o. ?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. ?What is it?GPSDO (Global Positioning System Disciplined Oscillator), also known as GPS Tamed constant temperature crystal oscillator, GPS Tamed clock, 10MHz standard signal source. Compared with the ordinary time base, it has higher accuracy, lower temperature drift, and more stable output. It is the use of GPS 1PPS signal, microcontroller comparison, by the microcontroller output 16Bit PWM to control the isothermal crystal output accuracy, isothermal crystal frequency fine-tuning voltage is.
