National Instruments PXI-2544 PXI RF Multiplexer Switch Module

The NI PXI-2544 (Part Number: 778572-44) is a terminated, 8x1 Multiplexer Switch Module intended for directing RF signals up to 6.6 GHz in production test applications. It includes superior solid-state relays that offer valuable advantages, including boundless relay life and a quick exchanging time. Front-mounted SMA connectors give a simple association with RF gadgets and the module highlights termination on each COM line and channel. The 50 terminations on the channel and COM lines limits impressions of the RF signals and ensures the instruments.

The data transmission specification of this switch module is not an absolute specification and is determined by merchant guidelines. Although the user can course higher recurrence signals through this switch module, they experience more degradation than those at lower frequencies. To decide the best switch module for a specific application, refer to the insertion loss, voltage standing wave ratio (VSWR), and isolation specifications of the item for the data bandwidth required.

The NI PXI-2544 utilizes the innate timing and synchronization capacities of the PXI platform to communicate with different instruments inside the PXI chassis. The user can store a list of switch associations in the memory onboard the switch module. Then, the user can utilize the integrated hardware scanning and triggering engine to advance the switch sequence and quickly communicate with any PXI instrument that can send and get computerized triggers, such as a DMM or oscilloscope. This propelled exchanging technique expels the software overhead and diminishes the bus latency related with conventional software-controlled switching tasks for speedier test execution with more repeatable timing.
