Control Software ATC
ATC control software provides all measurement settings and results in the display. Its main interface adopts a popular menu structure, including a menu bar, toolbar, test item selection, test condition setting, result reading, and other areas. The whole software interface is intuitive and easy to operate
In addition to the basic test function, ATC also supports automatic tests, which can produce rich graphical results and reports, Pass / Fail judgment, etc. Reports can be exported to PDF, HTML, Excel, CSV, RTF or MATLAB, and other formats.
Because all ABTEC audio analyzers use the same control software, it makes the test and results easier to share. All test settings can be saved in the same engineering file, which is convenient for R & D and production to share engineering files. Users can even embed the existing waveform file and graphic data into the engineering files, greatly optimizing the test.
