Version report: V1~V2

Reports and testing methodology is gradually updated. We try to generate the report in such a way that it would have been a single kind of report for all devices, convenient for direct comparison.

We constantly introduce new tests and improving the options for displaying graphs and parameters. It introduces different changes in reports. Because reports are generated automatically, the updates do not take much time.

In the development and implementation of new tests, new reports are more complete. To update some charts and tables may require additional time to process the raw data separately for each device.

Some devices require re-testing.

This model was tested for a long time and the report does not have the following graphs:

This model was tested for a long time and the report does not have the following graphs:

  • Harmonic distortion spectrum vs amplitude vs loaded
  • Spectrum of IMD SMPTE vs Level
  • Spectrum of IMD CCIF vs Level
  • Spectrum of Multitone Distortion vs Level vs Load
  • Crosstalk
