| description | PROBLEM TO BE SOLVED: To provide an oscillator low in cost, high in reliability and capable of executing highly precise oscillation, while a temperature characteristic capable of being can easily be set. SOLUTION: In this oscillator, the temperature measured by a thermistor 1 is converted into a digital signal by an A/D converter 2 and is outputted to a CPU 3. The CPU 3 outputs a frequency range stored in accordance with a temperature threshold equivalent to the measured temperature stored in a memory 4 to a D/A converter 5. The D/A converter 5 changes the frequency, which VCXO 6 oscillates. |
