Product Description:

The PS-Cryo 4K cryogenic probe station is an advanced and highly specialized instrument designed for precision testing and measurement at extremely low temperatures. Engineered to meet the demanding requirements of modern research and development in fields such as quantum computing, semiconductor device characterization, and cryogenic electronics, this probe station offers unparalleled performance and versatility. One of the standout features of the PS-Cryo 4K cryogenic probe station is its exceptional thermal management system. The thermal anchor ensures that the temperature difference between the probe holder and the sample stage remains below 10 K, providing a stable and uniform cryogenic environment. This precise temperature control is critical for obtaining accurate and reliable measurements of devices operating at cryogenic temperatures.

In addition to its superior thermal performance, the PS-Cryo 4K cryogenic probe station boasts a low-temperature vacuum capability with pressures reaching less than 1.2E-3 Pa. This ultra-high vacuum environment minimizes contamination and thermal conduction through residual gases, further enhancing measurement precision and device integrity during testing. The vacuum system is integral to the station’s ability to maintain low vibration levels, making it an ideal choice for sensitive measurements where mechanical disturbances can severely impact results. This combination of low vibration and high vacuum conditions classifies the PS-Cryo as a low-vibration high-vacuum cryogenic probe station, setting it apart from conventional setups.

Flexibility and scalability are also key aspects of this cryogenic probe station. Standard configurations come equipped with four probe arms, allowing simultaneous multi-point probing of devices. For more complex testing scenarios, the station supports up to eight probe arms, enabling researchers to expand their experimental capabilities without compromising precision or accessibility. The probe arms themselves feature a generous stroke range along three axes—X, Y, and Z—with travel distances of 50 mm, 25 mm, and 25 mm respectively. This extensive movement range facilitates precise positioning and alignment of probes on intricate device structures, ensuring optimal contact and measurement fidelity.

Microwave compatibility is another critical attribute of the PS-Cryo 4K cryogenic probe station. It supports a broad frequency spectrum from DC up to 67 GHz, making it suitable for a wide array of high-frequency device characterizations. The station is equipped with microwave probes featuring K-type connectors that operate effectively from 0 to 40 GHz, as well as 1.85 mm connectors designed to handle frequencies up to 67 GHz. This broad frequency coverage enables researchers to perform comprehensive microwave and RF testing at cryogenic temperatures, a capability essential for the development of next-generation communication devices and quantum components.

Overall, the PS-Cryo 4K cryogenic probe station represents a cutting-edge solution for researchers requiring a reliable, high-performance platform for low-temperature device testing. Its combination of precise thermal anchoring, ultra-high vacuum environment, flexible probe arm configurations, and extensive microwave frequency support ensures it meets the stringent demands of advanced scientific exploration.
