The FETtest Model 3401E is designed to test two leaded devices
such as diodes, voltage references, current limiters, TVS's, SSOVP
The 3401E is produced in the same cabinet as the 3400E, however,
the number of programmable power supplies and device lead signal
paths available in the 3400E have been reduced.
Additionally, the 3401E contains a different matrix board that
enables the 3401E to perform the unique parameters required when
testing SSOVP and SIDAC devices. The 3400E cannot test these devices.
