Description
The Part Number 778572-55 identifies a specific model within the category of PXI Switches. This model, designated as PXI-2555, is a 2.5 GHz 75 Ohm 4X1 Terminated Multiplexer. It is categorized as a PXI RF Multiplexer Switch Module, designed to facilitate RF signal routing within a PXI chassis.
The PXI-2555 features internal termination which is crucial for preventing high-frequency control reflections, ensuring signal integrity, and improving overall system performance. This termination design is particularly beneficial in Video RF applications, where maintaining signal fidelity is critical.
Among its key characteristics, the PXI-2555 boasts excellent insertion loss, VSWR (Voltage Standing Wave Ratio), and isolation parameters. These features contribute to its high performance in demanding RF signal routing tasks. Additionally, the module offers onboard relay count tracking and is configurable for scan list processing, enhancing its flexibility and usability in complex setups.
The Control Logic is implemented onboard, facilitating efficient relay opening and closing operations. This is complemented by the ability to store up to 1024 irregular scanning instructions in its Scan List Memory. Such capability allows for sophisticated scanning sequences, making the module highly adaptable to various testing and measurement scenarios.
Moreover, the PXI-2555 includes an External Trigger Input. This input is compatible with TTL voltage levels and requires a minimum pulse width of 70 ns, enabling precise timing and synchronization with external events or instruments.
