The Breakout Box by RUETZ SYSTEM SOLUTIONS complements an ECL test setup to reach 100 percent automation. Additionally, the Breakout Box raises the accuracy of the measurement results. Another advantage is that no plugging or replugging of cables has to be executed. Time-critical measurements are started by the internal microcontroller based on trigger conditions. Subsequently they may be read out and analyzed offline. Matching as a supplement we provide the ECL Compliance Testsuite.
