NI PXI-2532B Radio Frequency switch module

Product Overview
Pxi-2532b is a PXI bus-based RF switch module launched by National Instruments (NI). It is mainly used to achieve high-speed switching and routing of RF signals in automatic test systems, providing flexible and reliable signal control solutions for various RF test applications.

Performance parameters
Frequency range: DC to 26.5 GHz, covering a wide range from DC to millimeter-wave bands, and can meet the testing requirements of various high-end RF applications, such as 5G millimeter-wave communication, satellite communication, radar and other fields.
Switch configuration: It offers a wide range of switch configuration options, including single-pole double-throw (SPDT), single-pole multi-throw (SPMT), etc. Users can flexibly choose according to their specific test requirements to achieve different signal routing topologies.
Insertion loss: Throughout the entire frequency range, the insertion loss is relatively low, with typical values ranging from 2 to 4 dB. This helps ensure the integrity and strength of the signal during transmission and reduces the impact of signal attenuation on test results.
Isolation: It features outstanding isolation performance, with an isolation degree typically greater than 80 dB. This effectively suppresses signal crosstalk between channels, ensuring the independence of signals from each channel and enhancing the accuracy and reliability of the test.
Switching speed: The switching speed of the switch is extremely fast, with typical switching times at the tens of nanoseconds level. It can meet the testing requirements of rapidly changing RF signals and is suitable for testing scenarios with high real-time requirements, such as rapid frequency-hopping communication testing and high-speed radar signal processing.

Functional characteristics
High-precision RF signal switching: By adopting advanced RF switching technology, it can precisely control the on-off and routing of RF signals, ensuring accurate signal transmission between different channels and meeting the requirements of high-precision RF testing.
Multi-channel parallel switching: Supports simultaneous switching of multiple channels, and can achieve synchronous control of multiple channels through software programming, facilitating the construction of complex multi-channel RF test systems and improving test efficiency.
Hot-swappable function: It features hot-swappable characteristics, allowing modules to be safely inserted or removed during system operation without shutting down the entire test system. This significantly enhances the maintainability and flexibility of the system, reducing the time and cost losses caused by system downtime.
Software compatibility: Highly compatible with various test software and development environments of NI, such as LabVIEW, LabWindows/CVI, etc. It also supports multiple third-party test software, facilitating users’ system integration and test program development, and reducing development difficulty and cost.
