OVERVIEW 

(6 frequencies can be measured, of which 4 can customize other frequency points within the 1M-100M range)

 MD-8B  broadband clock tester is suitable for electronic product clock circuits using 4M, 4.194304M, 12M, 14.31818M, 32768Hz, 1Hz,for example:auto electronic clock, intelligent meter, computer motherboard, thermostat, timer, electronic scale and electronic cash register time function precision measurement. Its appearance is depicted as Figure.1.Among them, four frequency points in the MHz level can be customized to other frequencies between 1-100M.

  MD-8B broadband clock tester      

MD-8B broadband clock tester MD-8B's RS232 interface can be used to connect MD-8B and computer in order to gather testing results. Additionally, our MD-8B broadband clock tester has a tinny probe with it, which can suits the testing of bigger circuit boards.

MD-8B has five installs,6 frequency grades:

1. ppm:part per million, accurate to 0.1ppm

2. s/d:seconds/day, accurate to 0.01 seconds

3. s/m:seconds/month, accurate to 0.1 seconds

4. s/y:seconds/year

5. F:4M,4.194304M,12M,14.31818M,32768Hz,1Hz frequency deviation.

Compared with the same type of products from other companies, our MD-8B has the following advantages:

1. with a more sensitive sensor in it to receive weak signal;

2. taking non-contact method;

3. thinner shell making it more easy to use and more suitable for the pipeline;

4. with advanced CPU and TCXO(Temperature Compensated Crystal Oscillator); 

5.  with a 16-level signal strength indicator;

6. with the function of alarming, and the user can set alarming range;

7. easy setting procedure;

8. accuracy is better than 0.2ppm;
