• RF 1Hz-50MHz LED Digital Crystal Oscillator Frequency Counter Tester Meter DIY Kits Frequency Meter Digital USB 5V Interface Color: redSize: 8 × five cmApplicable to:Crystal measures (4M, 16M crystal)Crystal measures (20M, 11 crystal oscillator) FeatureThis is a frequency meter in keeping with PIC microcontroller, minus frequency settingCrystal dimension function and programmable, five-digit display, intuitive and convenientAll use of sequence components, the circuit is simple and easy to make 1 Hz - 50 MHz (for 1 Hz - 50 MHz) 1 measurable frequency range;2 The most typical measure of the oscillation frequency of the crystal;3 Five-digit precision resolution (eg 0 kHz, 4 MHz, 11 MHz);4 Automatic vary conversion without guide handover;5 Programmable subtraction frequency settings, such as transceivers for measuring devices;In the 15 seconds, if there's a frequency auto-shutdown display within the chosen power-saving mode, there isn't any significant change;7 You can use the typical USB 5V interface to supply power, otherwise you can use an exterior DC energy delivery or a 9V battery The number of aspects is small, all ingredients in the manufacturing line are easy to install Instruction manual1 All cord units, PCB presses are wisely soldered,2 After the welding is completed, enter the sign with a typical video supply Adjust the yellow adjustable capacitor in order that the display is equivalent to the value of the signal frequency Including filler1 frequency meter from 1Hz to 50MHz (DIY kit, no longer assembled)
