New 1Hz-50MHz frequency counter / crystal measuring / five digital display kit NOTE:ITS kit ,no finished This is a frequency meter based on PIC microcontroller, add and subtract with crystal vibration measurement functions and programmable frequency Settings, five digital tube display, convenient and intuitive, easy to make. The circuit features: Measured frequency range 1 hz to 50 MHZ (1 hz to 50 MHZ); Can measure most commonly used crystals of oscillation frequency; Five precision resolution (e.g., 0.0050 KHZ, 0.0050 MHZ, 11.059 MHZ); Automatic range switching, do not need artificial switch; Programmable Settings, add and subtract frequency used for measuring the transceiver and other equipment; Optional power saving mode, if there is no obvious change frequency within 15 seconds automatically closed display; Can use generic USB interface power supply, also can use an external power supply or 9 v battery. Element number less, all into components, simple installation and debugging. NOTE: 32.768KHZ crystal can not be measured , the condition is limited only tested 4-20MHZ crystal can be measured , 48MHZ also can be measured , but because this is the use of octave harmonic oscillator , so 48MHZ crystal displays measuring fundamental frequency 16MHZ. You can also IN and - direct input frequency signal ( ground ) between measurements. Decimal point flashes to indicate whether the unit of measurement , when the test frequency value for KHZ decimal point flashes when the test frequency is MHZ decimal point is not blinking . Crystal vibration measurement (4 MHZ): Crystal vibration measurement (8 MHZ): Crystal vibration measurement (11.0592 MHZ): Crystal vibration measurement (20 MHZ): Payment Policy: We ONLY accepted PayPal payment.
