The Keysight Technologies, Inc. 4082A parametric test system is designed to perform fast and precise DC measurements, capacitance measurements, and other high frequency applications such as ring oscillator measurement. The system supports up to eight source monitor units (SMUs). Each SMU is self-calibrating, and can be individually configured to force either current or voltage, as well as simultaneously measure either current or voltage. The system also supports a fully guarded switching matrix customizable from 12 to 48 pins. One special additional pin is dedicated as a chuck connection.The Keysight 4082A can be constructed in either a low-current or an ultra-low current configuration, depending upon the type of matrix card specified. Only 4082A models containing the ultra-low current matrix cards can use the high-resolution SMU (HRSMU).
An optional high-speed capacitance measurement unit (HSCMU) is available for the 4082A, which enables the measurement of capacitance and impedance with unprecedented speed. External instruments can be integrated into the system via six auxiliary input ports or forty eight extended path inputs. The extended path inputs allow the user to connect external signals directly to the DUT pins.
Another option offered for the 4082A is a high-frequency switching matrix. The high-frequency matrix is organized as two 3 x 24 matrices (six inputs in total), and 1 TO 2 furnished cables may be used on each matrix pair to create one 3 x 48 matrix (three inputs in total). The system also has one 1.6 A ground unit.
