3. The shortcut function key can be used to transform any menu interfaces at any moment.
4. Digital volume control can monitor any phone at any moment.
5. Soft switch of power supply can realize the functions of timed start and timed test, etc.
6. Clear historical alarm records at any moment
7. Inject outburst error or rate error at any moment
8. Freely run or stop test
9. The display of test setup and test result can be freely transformed.
10. Intuitionistic direction keys make setting simple and effective, and can randomly zoom or move the histogram.
11. The built-in high-performance backup battery can successively work for 8 hours when the power is full.
12. We expediently enter into many additional functions with function keys, and can select the needed functions through the concise menu without complex operations.
13. RS232 printing interface can print any single screen result or the whole results.
14. The data port can be transformed into V series interface of various standards and co-directional 64kbit/s interface through proper-matched cable.
15. The side sketch map: Balance and unbalance interfaces can be well used in all kinds of occasions.
