On the PC, the database keeps all the history, testing setup, and the final snap
shot of measured signals. If you want to back up the setup of ALL tests, simply
back up or export the complete database.
The testing data is organized with hierarchy of Tests>Runs >Measured Signals.
On the PC’s hard disk, a test folder containing multiple RUN folders is also
created. A test project file, *.STK, is a copy of the test setup in the database
with the same test name. It is a single file and can be easily transported to
another PC.
The Run folders keep multiple measured signals saved by the user or the test.
These measured signals are not stored in the database.
Each file of Measured Signals contains multiple signals that are captured at one
time. We call these signals collectively a frame of data.
If the user sets the Front-End to black box mode or selects to save the Measured
Signals to the Front-End instead of the PC, the measured signals will be saved to
the front-end hardware instead of the PC. Users can always download the
measured data from the Front-End to the PC.
On the front-end hardware, the most recent eight tests are kept in the flash
memory, so the hardware can run without the PC. If operated with the PC, the
software will automatically synchronize the test configuration from the PC to the
Front-End.
