Electronic Measurement Laboratory

The Electronic Measurement Laboratory, or Wright Room 5, is the research lab of John Scofield. The layout of the lab is shown in the drawing below. The lab contains the usual assortment of cabinets, counter space, and a laboratory sink. The main feature of the lab is the 10 ft. x 10 ft. x 10 ft. RF-shielded enclosure. This room-within-a-room provides for a low-noise measurement environment.

The Electronics Measurement Lab is presently set up to perform electrical measurements for characterizing solar cells, specifically light and dark current-voltage (I-V) characteristics and admittance measurements. Measurement systems include a home-made solar simulator and probe station, an HP-3562A dynamic signal analyzer, an HP-3325B frequency synthesizer, Keithely 199 dmm/scanner, an HP-4140B picammeter/voltage source, and a Tektronix storage scope. Instruments are controlled by one of several intel-based personal computers using the GPIB.
