TestC - Mini test system
Use case
LXI unit control and test case validation
In cooperation with Rigol Technologies EU GmbH, Viconnis has launched an innovative test concept for the pre-validation of LXI laboratory equipment. By means of the test software TestC and the Raspberry PI mini test system, selected test sequences can be automated and documented in advance, so that the customer / laboratory user can use his desired test functions in a particularly convenient and reproducible and transferable way through test automation and on the basis of the supplementary test documentation (available later as an application note).
Automated Fault Injection for Total Test Coverage
Together with Razorcat GmbH, Viconnis has developed an innovative test concept with TestC API, Raspberry PI Mini Test System and TESSY 4.1 for software and hardware testing.
Further information on the TESSY 4.1 software from Razorcat GmbH is available from here.
Flexible - Cost-effective - Scalable
- Scalable from low cost (Minitest) to high performance (ATE*)
- Technology connection for evaluation boards, test systems and devices
- Test system model with limitations and restrictions in simulation
- Transferable, reusable test content for agile testing
- Experience and test case based communication of all parties involved
Architecture for analogue and digital tests
INTEGRATIVE TEST ARCHITECTURE
Analyse - Test - Learn at an early stage
Raspberry PI® (RPI) as test client with operator interface*.
- Communication via Ethernet, WLAN, USB*
- Receiver for TestC© commands
- Execution of the test contents
- Result Feedback from Raspberry PI ® to TestC© for alignment - Pass / Fail
- Handover of native LXI raw data to test units (e.g. LXI units)
Cooperative testing with several RPI®
- Master / Multislave
- Master Production : e.g. Master USB System Tests / Slave: Minitester Cooperation
- Multiple synchronised Analogue / Digital Raspberry PI®
- Just in Time- HW Stimuli for SW Tests - Pass and HW Fail braches*.
RPI® as test control and test execution
