The Model 4431T is a turnkey shielded bag test system that includes the Test Unit, Oscilloscope, Computer and ETS Test Suite Manager software that is designed to perform testing in accordance with ESDA STM11.31 & EIA-541. The ETS Model 4431T Shielded Bag Test System is a complete system that generates the specified ESD pulse applied to the outside surface of the bag and detects either the voltage or current induced onto a capacitive sensor placed inside the bag. The Test Suite Manager Program displays the waveforms, calculates the energy of the discharge pulse induced inside the test bag and processes the data in accordance with ESD STM 11.31. It also automatically controls the Model 4431 and program the oscilloscope.
Automated testing provides ease of use,efficiency and eliminates human errors.
