Tektronix VX4363 Relay Switch Module
Tektronix’ VX4363 is an SPST (single-pole/single-throw), 32-channel relay switch module that is used in conjunction with an automated test and measurement system to route signals between devices-under-test, measurement instrumentation, and/or other devices. As a result of its ability to automate the routing of signals between multiple DUTs and multiple instrumentation devices, the VX4363 enables engineers to significantly reduce the amount of manual labor required to perform the majority of the testing tasks associated with developing and/or maintaining products; and by doing so, reduces the opportunity for errors in the process, and increases productivity and efficiency in both the manufacturing and research and development laboratories.
Modules like the VX4363 are typically mounted within a switch mainframe or test chassis and are optimized for use in scanner and/or multiplexer configurations, which are common in automated test equipment designs. For example, when using a scanner configuration, a module could be used to sequentially route a single measurement device, such as a digital multimeter, through multiple DUT sensor or test point locations to measure parameters such as temperature or voltage at each location. When using a multiplexer configuration, the same module can be configured to allow multiple DUT sensors or test points to be simultaneously or non-sequentially routed to one or more measurement devices.
Engineers select these types of switching hardware solutions because they help to preserve signal integrity and the accuracy of their system. The performance of the relays included in this type of solution, including characteristics such as contact resistance and switching time, have a direct impact on the fidelity of the measurements taken, particularly in low-voltage or high-impedance circuits. The current rating of the VX4363’s relays indicate the ability of the relays to support a large load per channel, thus providing a broad range of options for power and function testing applications. Designing a solution around this type of module requires a detailed understanding of the overall system architecture, including the capabilities of the mainframe controls, and the types of signals being routed throughout the system, to ensure reliable and accurate automated testing operations.
