Test
Information starts with testing
TREX will help you to turn your
data into valuable information!
Do you struggle with getting the right information
out of the enourmous generated amount of
test and measurement data?
T.R.EX – what means TREX?
TREX combines SSI know-how about acoustics and measurement technology as well as technical experience in relation to electro-acoustics and error analysis on micro speakers in one software package.
Modular plugin technology/architecture embedded into a high sophisticated framework using a common communication data bus which provides the dynamical call of the plugin library inner a framework or the discrete call of the .exe as a separate Standalone plugin application.
T.R.EX – Test
Gathering the right informations starts with performing the right tests. TREX enables you to design your test sequences flexibly, generate sophisticated test signals, applying advanced filter design features and control various devices. TREX comes along with a broad set of I/O and data acquisition interfaces and can be easily extended to proprietry interfaces if needed.
For working on the highest grade of flexibility TREX provides a high sophisticated sequencer which would be able to remote control different 3rd party measurement systems and even more could provide discrete sequence steps for accessing and controlling the functions of the diverse measurement API’s. All test data, as well the measurement data coming from 3rd party test system, would be transferred (wrapped) into a common data format and stored onto a data server on which they get indexed within seconds to be searchable and accessable.

T.R.EX – Rate
- Quality control
- OQC/IPC
- End of line test
- Limits rating
- Limits and customer EQ curves would be loaded from main TREX test configuration file
Based on acquired signals coming from various sensors, CTQ (critical to quality) parameters are calculated within trex test and analyzer modules.
During the rating process a standard or limit value according a particular scale is assigned.
This makes the trex application fully usable as end of line production test tool.
For those who don’t have a full blown MES backend (manufacturing execution system) it offers a basic production yield tracking and failure reporting.
TREX offers a wide range of statistical tools for a quick and reliable analyse of the measurement data, without time consuming export and import processing into different tools.
TREX offers offline as well server access to the data.
T.R.EX – Explore
The viewer functionality of TREX gives you a wide flexibility to select the relevant data to generate tailored and meaningful reports. TREX offers offline and remote access to the data. More under data managment. With pre-selector engine of explorer, indexed measurement data could be found, sorted and grouped into buffer on which TREX Viewer would have access for further explore tasks. Following features would be provided by TREX Explorer:
- Statistic
- Sorting, grouping and clustering
- Post processing
- Automatic report generator
- Correlation of different measurement systems based on common data format
- Analyzing different kinds of measurement in one viewer at the same time (e.g.: acoustic data, mechanical data, IQC, simulation, …)
The big advantage would be the common data format which makes it possible to compare and view measurement data coming from different measurement systems like, APX, Soundcheck, … each together in one viewer.
Further common data processing, reporting and correlations would be comfortable.
T.R.EX – Data Management
TREX stores all the measurement data, independently coming from TREX Test Engine or from another 3rd party measurement system like APX or Soundcheck, in a common data format onto server where these data get indexed and would get searchable and sortable in very comfortable way. Currently we are working on APX and Soundcheck data integration. The core of TREX is the flexibility in processing data from different sources and different data formats. TREX transfers all kind of data formats into one unique format and stores the data in a database. The indexing feature allows you to link your data at all time to the relevant DUT. This gives you unique transparency, traceability and analysing power from early prototyping to mass production. The integrated report manager gives you the flexibiltiy to generate tailored reports from sophisticated lab analyzing to process yield tracking or quality control.
T.R.EX – Test Specification Management
Test Specifications and used calibration files would be stored centrally on indexing data server which makes the test setups easy to administrate, searchable and loadable from every Test Machine and R&D PC.
The metadata ID’s of Test Specification would be linked to every corresponding measurement file which makes conclusions and a tracing regarding the used test parameter to the current measurement data possible.
A common project file would contain:
- Test specification
- Test sequence
- Plugin configuration list
- All settings of used plugins
- Signal-Generator parameters and all imported audio files like .wav files
- All HW settings (special measurement engineer admin mode for reproducing testers on production line)
- Tracing metadata
- Project metadata
- Customer required EQ curves
- Comments
