Remote PreAmp Option for 4200-SMU and 4210-SMU The low current measurement capabilities of any SMU can be extended by adding an optional Remote PreAmp (Model 4200-PA).

The Model 4200-PA provides 0.1fA resolution by effectively adding five current ranges to either SMU model. The PreAmp module is fully integrated with the system; to the user, the SMU simply appears to have additional measurement resolution available. The Remote PreAmp is shipped installed on the back panel of the Model 4200-SCS for local operation. This installation allows for standard cabling to a prober, test fixture, or switch matrix. Users can remove the PreAmp from the back panel and place it in a remote location (such as in a light-tight enclosure or on the prober platen) to eliminate measurement problems due to long cables. Platen mounts and triax panel mount accessories are available. Remote PreAmps are installed at the factory in numerical order, i.e., SMU1, SMU2, SMU3 . . . up to the number of PreAmps specified.
