Lake Shore launches ultra-low-noise excitation source for material and scientific R&D

Lake Shore Cryotronics Inc of Westerville, near Columbus, OH, USA (which makes scientific sensors, instruments and systems for measurement and control) says that its new MeasureReady 155 Precision I/V Source offers the performance required by researchers for a precise, low-noise source of current or voltage in the lab.
When characterizing materials, the cleaner the excitation signal, the better the end measurements. Lake Shore says that the 155 provides the precise, very low-noise output needed for such measurements, partly because it employs the same proven noise-rejection technology used in the firm’s cryogenic thermometry products. The source generates just 200nV RMS (1µVp-p) of low-frequency noise and 7µV RMS of higher-frequency noise in the 10mV DC range — all without the need to add any external filters. It also provides DC low-noise performance without compromising AC bandwidth.
Because it generates less noise, the source provides a solid foundation for users performing I-V curve, Hall-effect, resistance, resistivity and other fundamental measurements of novel materials and early-stage devices. The source is also suitable for high-accuracy device testing, as well as semiconductor material and device researchers who need a high-quality source to excite samples.
The 155 source is also straightforward to operate, it is claimed. Its uncluttered touch display with a unique TiltView screen presents a natural user interface, with no confusing buttons to navigate. Wi-Fi, USB and LAN connectivity allow easy integration with systems using LabVIEW, .NET and other software. Also included is a unique mobile app, which allows users to operate the instrument remotely, whether in the same room or further away.
