Jitter analysis

Jitter in digital audio may cause audible distortion in the output signal,manifested in the form of jitter sidebands. Testing of jitter tolerance can reveal the distortion caused by jitter,but because its testing is difficult and time-consuming,many engineers do this in circuits and It is usually ignored when designing components. The jitter generation and analysis functions of the X5 series analyzers can simplify the testing of jitter signals.

Built for the testing required by power amplifier designers

Automatically test maximum continuous output power and maximum peak output power,DIM intermodulation distortion test,use adjusted frequency sweep to view power spectrum,and other test items specified in CEA-2006 and CEA-490A standards. In addition to traditional common mode In addition to the rejection ratio test,X5 can also perform the common mode rejection ratio test that complies with the IEC60268 Section 14.15.1 standard.

Code-free automation and comprehensive API interface

AS SYS software is currently the most advanced audio test interface software. Complex test processes such as user prompts,upper/lower limit settings,and calling external applications,etc.,can all be implemented directly in the X5 software interface,saving time and money. At the same time,it also greatly reduces the workload caused by future test system upgrades,because there is no need to use code at all.

To create customized or automated test programs for test applications,you can use X5's comprehensive API interface,which can be integrated into development environments such as VB.NET,C#.NET,MATLAB,and LabVIEW. And the created project files and automated test programs can be Shared use of X5 instruments worldwide.

Universal software platform

In practice,all audio analyzers use the same control software,making testing and sharing results easier. All test-related settings are saved in a single project file,which can be copied between development and all production plants. The same test project becomes very simple and convenient. Users can even embed waveform files and test result images into project files.

From the perspective of customers,suppliers,manufacturers or management,automatically generate rich graphical result reports,as well as highlighted PASS/FAIL result judgments,etc. The report can be exported to PDF,HTML,Excel,CSV,RTF or MATLAB,etc. Files in multiple formats.
