NI PXI-2546 PXI bus Radio Frequency Multiplexing switch module

NI PXI-2546 PXI bus Radio Frequency Multiplexing switch module

Basic parameters
Frequency range: DC to 2.7GHz.
Channel configuration: Two sets of 4×1 multiplexers with a total of 8 channels, enabling flexible switching from 8 input signals to 2 output channels.
Characteristic impedance: 50Ω, matching the common impedance of RF systems, ensuring the integrity and efficiency of signals during transmission.

Performance characteristics
Insertion loss: Up to -1.35 dB. A lower insertion loss ensures that the power loss of the signal when passing through the switch module is small, guaranteeing signal quality.
Voltage Standing Wave Ratio (VSWR) : This module features excellent VSWR parameters, ensuring low signal reflection and high transmission efficiency.
Isolation degree: It has a high isolation degree, which can effectively suppress signal crosstalk between channels, reduce signal attenuation and distortion, and improve the accuracy and reliability of tests.
Relay types: A variety of relay types are available for selection, including electromechanical armature relays, reed relays, field-effect transistor (FET) relays, and solid-state relays, etc. Users can choose the appropriate relay type based on their specific application requirements.
Trigger function: Supports trigger function, which can control the switching operation based on external trigger signals, facilitating synchronous operation with other devices or instruments. It is suitable for test scenarios that require precise synchronization.

Other characteristics
Internal termination options: It provides internal termination functionality, which helps prevent high-power reflections generated by open channels in the module and is suitable for RF applications where reflections may damage the signal source.
Relay counting and tracking: The on-board relay counting and tracking function can help users predict the lifespan of relays, facilitating early maintenance and replacement, and reducing unexpected system downtime.
Software compatibility: Programming can be carried out using the NI-Switch controller software compatible with IVI, accompanied by help documentation, sample programs, and front-end applications for intelligent switch control, facilitating users’ development and debugging. Meanwhile, it also has good compatibility with other test software of NI (such as LabVIEW) and development environments, facilitating system integration and test program development.
