NI PXI-2535 high-performance RF switch module

NI PXI-2535 high-performance RF switch module

Specification parameters
Frequency range: It can cover a wide frequency range of DC-26.5 GHz, meeting numerous high-frequency RF testing requirements. It is applicable in both the millimeter-wave band in the communication field and other high-frequency application scenarios.
Switch configuration: It offers a variety of flexible switch configuration options, such as single-pole double-throw (SPDT) and single-pole multi-throw (SPnT), which can be selected based on the architecture of different test systems and signal routing requirements.
Insertion loss: The insertion loss is relatively low throughout the entire operating frequency range, generally ranging from 2 to 4dB, which can effectively reduce signal attenuation during transmission and ensure signal strength and quality.
Isolation degree: It has a relatively high isolation degree, usually greater than 80dB, which can effectively suppress signal crosstalk between channels, ensure the independence of signals in each channel, and improve test accuracy.
Switching speed: The switching speed of the switch is relatively fast, with typical switching times ranging from tens of nanoseconds to microseconds. It can quickly respond to the control instructions of the test system and meet the requirements of test scenarios with high real-time performance.

Functional characteristics
High-precision signal switching: Advanced RF switching technology is adopted to achieve high-precision on-off and routing control of RF signals, ensuring accurate signal transmission between different channels and meeting the strict requirements of high-precision RF testing.
Multi-channel synchronous control: Supports simultaneous switching of multiple channels. Multi-channel synchronous control can be achieved through software programming or external triggering, facilitating the construction of complex multi-channel RF test systems and enhancing test efficiency.
Hot-swappable function: It supports hot-swappable, allowing modules to be safely inserted or removed while the system is running without shutting down the entire test system. This enhances the maintainability and flexibility of the system and reduces the time and cost losses caused by system downtime.
Software compatibility: It has good compatibility with NI’s testing software (such as LabVIEW) and other third-party testing software, facilitating users’ system integration and test program development, and shortening the development cycle.
