8 Digit Signal Frequency Counter Meter Tester Led

Features:
With Microchip's PIC16F648A, 2.4 GHz frequency meter. 
Using temperature-compensated voltage controlled crystal oscillator (2.5 ppm VC-TCXO). 
Unique gate control and precise time algorithm (non-timed interrupt). 
Gate (display refresh) time 0.01 seconds / 0.1 seconds / 1.0 seconds,real-time display frequency value. 
Single-ended input design, three-channel frequency measurement (low channel / high channel / Auto Channel). 
Dual frequency design, value and IF / down mode can be preset separately. 
Using eight 0.56 inches high brightness digital display, eight adjustable brightness. 
Circuit is simple and reasonable structure, two-button control, simple operation. 
The settings are automatically saved, boot directly call. 
1.Gate time 
0.01 seond 
0.10 second 
1.0 second 
2.Measurement channels (channels are low impedance) 
low channel 
Measuring range: 0.1 MHz ~ 60 MHz 
Accuracy: ± 100Hz (0.01 1s gate time) 
± 10Hz (0.1 seconds gate) 
± 1Hz (1.0 seconds when the gate) 
Low channel sensitivity: 
0.1 MHz ~ 10 MHz: better than 60mVPP 
10 MHz ~ 60 MHz: better than 60mVPP 
60 MHz ~ 75 MHz: Not tested 
 high channel (divided by 64) 
Measuring range: 20 MHz ~ 2.4 GHz 
Accuracy: ± 6400Hz (0.01 seconds gate) 
± 640Hz (0.1 1s gate time) 
± 64Hz (1.0 1s gate time) 
High channel sensitivity: 
20 MHz ~ 30 MHz: better than 100mVPP 
30 MHz ~ 60 MHz: better than 50mVPP 
60 MHz ~ 2.4GHz: not tested 
 Auto Channel 
Automatically selected according to the input signal frequency high or low channel channel, identifying the frequency of 60 MHz. Such as when the input signal amplitude is greater than 60 MHz shortage can not automatically select high channel, the channel should manually select high frequency measurement. 
3.IF settings 
Independent double-IF design, adjust the minimum frequency step of 100 Hz, frequency range 0 ~ 99.9999 MHz, can be set to increase or decrease the IF frequency mode. 
4.Frequency reference 
Using 5032 package 13.000MHz Warming voltage controlled crystal oscillator (VC-TCXO), frequency stability of ± 2.5 ppm. 
5.Operating voltage 
DC Input: DC 9V ~ 15V (with reverse polarity protection) 
6.Current 
Maximum 160 mA (test conditions: ? DC12V power supply; ? blue LED; ? eight brightness) 
7.Eight LED display, the highest display eight digits.  
8.Eight LED brightness is adjustable, factory set to maximum brightness.
