Save time by using a Keithley 4200 with your Lake Shore probe station and controller to automatically run a diverse set of measurements over a range of temperatures without any repeated intervention. Learn more in a new application note detailing how this was done to characterize high electron-mobility transistor (pHEMT) devices at different cryogenic temperatures.
Option cards are still available that add additional functionality to your 340. The 3462 card doubles your sensor inputs to 4 total, and there are also thermocouple and capacitance cards remaining as well.
If you attended the APS March Meeting you might’ve gotten an early look at our Model 372 AC resistance bridge & temperature controller. Available this summer, it will be a great addition to any application requiring precise cryogenic temperature control (down to 10 mK) or for measuring very low-impedance devices and materials.
