The National Instruments PXI-2555 is a PXI RF Multiplexer Switch Module with part number 778572-55, featuring internal termination for video RF applications, optimized VSWR and high isolation to limit signal degradation, and includes relay count
The National Instruments PXI-2555, with part number 778572-55, is a PXI RF Multiplexer Switch Module designed for demanding RF applications, such as video RF, where its internal termination feature is crucial for preventing high-control reflections that could potentially damage the source. This module is engineered to deliver low insertion loss and optimized voltage standing wave ratio (VSWR) to ensure minimal signal degradation, while offering high isolation levels for improved signal integrity.
Equipped with onboard relay count tracking, the PXI-2555 allows users to predict the lifetime of the relays, thereby reducing the likelihood of unexpected system downtime. The module’s control logic facilitates the opening and closing of relays and can handle scan lists of up to 1024 instructions, which are stored in the onboard memory to enable the fastest scans without controller intervention.
Users can configure the PXI-2555 for either single scans or continuous looping through the scan list, with the added benefit of an external trigger input that offers greater flexibility in scan operation by allowing advancement between scan setups. This input is compatible with TTL voltage levels and is edge sensitive, enhancing the module’s adaptability to a variety of triggering scenarios.
