Green 0.1-60MHz 20MHz ~ 2.4GHz RF Singal Frequency Counter Cymometer Tester Meter

 

Fetures:
 
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.

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.
