You have a very hard time switching between CV and IV measurements (you may actually devote
separate probe stations to CV and IV just to avoid having to change cables). In addition, great care
has to be taken when cabling to a capacitance meter to insure that all of the capacitance
measurements are properly compensated.
The SCUU removes all of these worries and makes connection simple and easy. In addition, the
B1500A software automatically takes care of the multiplexing based upon the type of algorithm
selected from the front panel.
