User's Guide Agilent 16440A SMU/Pulse Generator Selector is one of the accessories available for Agilent 4155/4156 Semiconductor Parameter Analyzers. The selector is for automatically switching the unit (SMU or PGU) that is connected to a DUT pin according to the state (stress force state or measurement state). NOTE To use the selector, the 4155/4156 must be equipped with Agilent 41501 SMU/pulse generator expander that contains two PGUs. This manual consists of the following sections. Intr

User's Guide Operation Operation This section describes the operating theory of the selector. Agilent 4155/4156 can control the selector to automatically switch the unit (SMU or PGU) that is connected to a DUT pin according to the state (stress force state or measurement state). This is useful for performing reliability testing (stress testing) of DUTs. For example, the selector can connect a PGU to the DUT for forcing ac stress, then can switch and connect an SMU for measuring dc character

User's Guide Operation The following figure shows a simple circuit diagram of the selector (selector expander). The CH 1 and CH 3 circuits are different from the CH 2 and CH 4 circuits. Each channel has one mechanical relay for SMU and one mechanical relay for PGU, but the CH 1 and CH 3 circuits also have a semiconductor relay for PGU. The relays are controlled by the 4155/4156 via the control circuit. The semiconductor relay is useful when you need to perform a lot of switching (for exampl

User's Guide Operation The switching state of a channel is indicated by the green LEDs on the selector front panel. The following table shows the relation of the relays and the LEDs for each switching state. States CH 1 and CH 3 CH 2 and CH 4 All open SMU on PGU on PGU open The "PGU open" state is useful if a lot of switching needs to be performed. When the switching state changes from "PGU on" to "PGU open", only the semiconductor relay switches. This reduces the amount of times the mechan
