National Instruments PXI-2798 PXI Transfer Switch Module

The National Instruments PXI-2798 (Part number: 782358-01) Transfer Switch Module can course RF or microwave signals in mechanized test applications. Intended to work with under 1 dB of insertion loss at up to 40 GHz, the PXI-2798 is relatively undetectable for signals at much lower frequencies. This Transfer Switch Module utilizes the inalienable timing and synchronization capacities of the PXI platform to represent different instruments inside the PXI chassis. The user can store a list of switch associations in memory onboard the switch sequence and afterward utilize the incorporated hardware scanning and triggering motor to advance the switch sequence and quickly communicate with any PXI instrument that can send and get advanced triggers, such as a DMM or oscilloscope. This advanced switching method evacuates the software overhead and lessens the bus latency related with traditional software-controlled switching tasks for speedier test execution with more repeatable timing.

To improve relay upkeep and increment reliability quality in high-channel-count frameworks, NI PXI Transfer Switch Modules offer propelled transfer health observing highlights, such as locally available relay count tracking, which is accessible on all NI switch modules, and utilitarian and resistive individual tests, accessible through the NI Switch Health Center. The NI Switch Health Center is a free application that installs with the NI-SWITCH driver that can be utilized to screen singular relay health, direct transfer substitution, and create client reports. Moreover, expansive changes in contact protection after some time can demonstrate that a relay is approaching, or has achieved, end of life.
