this Cymometer is 89C51 microcontroller and a few digital circuit several triode, and constitute a microwave integrated circuits. The maximum measurable frequency for 2G! Resolution of 1HZ! Circuit R16-R27 resistor 1K. This paper bag has produced two successful website after pictures! 2 SCH. A PCB document. A PDF document. HEX and a procedures document. Whenever produced by the PCB then good components, then burning procedures HEX file to SCM, can debug, I hope you succeed. These high stability oscillation circuit SCH document is a new addition. If we conditional use this circuit is a good one. As the frequency of dollars will be more stable. Frequency of PCB is my design. Design it very well, we hope that many opinions and suggestions. We should not amend the PCB document. Note : extracti
