1.This board is Frequency Counter which was already assembled and tested.
2.Frequency measurement 1Hz to 60MHz and Auto Range.
3.Frequency Input Sensitivity 200mV to 300mV. Frequency Measure cycle 1 second.
4.Frequency Measure Accuracy: Guarantee ±0.01%.
5.Onboard Microchip PIC16F883 (Crystal Oscillator 20MHz, +/-20 ppm), better than others onboard PIC16F628A (4MHz) Frequency Counter.
6.Power Circuit (TO-220, 7805, Vin=7V~16V, Vout=5V).16x2 Character LCD Display Module HD44780 Controller blue black light.
7.Three Keyboards Circuit to select two Mode:
(2)60MHz Frequency Counter + IF Offset (User definable IF Offset).
8.The programmable Mode and IF offset parameters are stored in PIC16F883 non-volatile EEPROM.
9.Programmable display calculation: Direct, VFO+IF, VFO-IF, IF-VFO.
