The Teradyne / Nextest Magnum EV Tester runs on the MAGNUM_X20 system. The Teradyne / Nextest Magnum EV Tester includes a PC.[1]

Automated test equipment (ATE) systems apply electrical signals to semiconductor devices and measure responses to verify functionality and performance. A semiconductor tester connects to a device under test through a test head and a load board or probe card.
A semiconductor tester connects to a device under test (DUT) through a test head and a load board or probe card. The tester's pin electronics generate stimulus signals and measure responses to determine whether the device meets its specifications.
The Magnum EV is employed in wafer-level probe testing and final test of packaged semiconductor devices. Such testers are used after wafer fabrication to identify defective die and after packaging to verify final device performance.
Automated test equipment is used to test a wide variety of semiconductor devices including microprocessors, memory chips, and analog integrated circuits. The Magnum EV tester can be applied to multiple device categories depending on its configuration.
