What are the key points of the techniques for integrating the 4285A in a scanner system?

In order to select an appropriate scanner, you need to determine the connection method (three-terminal, four-terminal, shielded four-terminal, etc) suitable for the impedance range of the devices to be measured. The basic connection configurations for using the 4285A with a multiplexer switch unit of a scanner are described in Application Note "Efficient Impedance Measurement of a Large Amount of Components by Using a Scanning System". The multi-channel compensation method for minimizing the discrepancies in measured values among channels is also described in this application note.
