*U.S. Patent #6, 501, 255, Dec., 2002, "Differential current source with active common mode reduction," Lake Shore Cryotronics, Inc.
The new Lake Shore Model 3726 scanner is designed for connecting to multiple ultra-low temperature measurement points in a system. With lower input noise and DC bias current, the 3726 scanner offers superior performance to the previous
generation 3716 scanner and will be capable of taking full advantage of the performance improvements built into the Model 372.
The Lake Shore Model 3708 8-channel preamp/scanner offers an exceptionally low voltage noise floor specification of just 2 nV/√vHz, improving the utility of the Model 372 AC resistance bridge for ultra-low AC resistance measurements.
