50 MHz Crystal Oscillator Frequency counter Testers DIY Kit 5 Resolution9224
Color: Red, Simple Construction , compact design, easy to install and debug.
Designed to measure the frequency of oscillation of most crystal oscillators.
Based on PIC minicontroller can measure the frequency of 1 Hz to 50 MHz.
Five digits of precision, for example kHz x.xxxx, MHz or .xxx x.xxxx MHz.
General for feeding USB interface can be used for power supply, AC adapter or a battery of 9 V can be used too, it is used.

Optional mode of power saving: can automatically convert the display if the frequency does not change significantly in 15 seconds
Very small number of components: a PIC16F628, 5, 7-segment LED screens, a 20 MHz crystal and some resistors
Material: PCB;. Frequency range: 1 Hz-50 MHz
Glass Test Range: 4 KHz-48 KHz
Built Item Size: 8 * 5.5 * 0.7 cm / 3.2 * 2.2 * 0.3 inches

Package Contents:
1 * Frequency Counter
