DSE EasyStand to implement the Graphical User Interfase

The system is build using DSE EasyStand modules for implementing the Graphical User Interface (GUI) and for Diversity Handling. National Instruments Audio Master software is used by the system to perform all audio measurements according to the required standards. Results are presented to the operator both on the GUI and in printable reports.

EasyStand in combination with WATS to ensure Test data

Diversity Handling is handled by DSE’s EasyStand toolbox and integrated with WATS MES to ensure consistent and controlled distribution and maintenance of test limits etc.

The system utilizes a modified version of TestStand’s sequential process model that integrates both DSE’s EasyStand and WATS MES.

WATS MES is a package based software distribution system delivered by Virinco.

Audio master and PXI chassis from National Instruments

The hardware includes a National Instruments PXI chassis which holds both the embedded controller PC and the instrumentation suite that make up National Instruments Audio Master.
