FREQUENCY COUNTER HC-F2700L 

Technical Specifications : 

1, the application of SCM control and computing, using scale integrated circuits, 
complete broadband such as precision and period measurements, counting down to 
achieve high resolution  
2, frequency measurement, measuring cycle, 13MHz standard frequency output  
3,100 MHz low-pass filter is provided below is to improve the low frequency 
performance, enhance immunity 
4, the completion of the 8-digit per second measurement and display of  
five, high accuracy, low power consumption, small size, exquisite, easy to carry.
 

2.7GHZ precision digital frequency meter  
    The instrument has four main functions: A channel frequency measurement, the 
channel frequency measurement, A-channel measuring cycle and the A-channel with 
input signal attenuation, low-pass filter function .  
The instrument can be widely used in laboratory, industrial and mining enterprises, 
universities, commissioning and maintenance of the wireless communication 
device. High-sensitivity measurement designed to meet the communications field UHF 
signals measured correctly and obtain the best measurement results.
