Test Adapters UNIMET

Test Adapters UNIMET

Family test adapters are a set of SW and HW.

SW is mostly designed as menu-driven for users comfort. The user does not need a standard compiler or dedicated language to make a test program e.g. for discrete devices.


Test adapters (TAxx) further extend the capability of base test station (M3000, UNIMET 3000, UNIMET 2020). They contain additional instruments necessary to test dedicated family of devices. We've successfully followed up on the development of M3000 test adapters originaly designed by SZ Testsysteme GmbH in Amerang. Our newly designed Test adapters are TA37 (Discrete semiconductors) and TA39 (OpAmps) meet new demands of modern semicondcutor era. We can of course still offer slightly redesigned, yet still compatible, versions of original Test Adapters by SZ Testsyteme. All TAs are controlled by SCADUS, our universal test software.

A complete delivered package of TAxx contains also so called GOLDEN devices i. e. devices with protocolled test results and reference Socket Adapters with dedicated device socket and application circuitry.
