USING THIS GUIDE This reference and programming guide contains condensed specifications, a summary of front panel operating controls. and IEEE-488 programming commands and examples for the Models 194A. 1941, and 1944A. It is intended to pro- vide a quick reference to the many available features of your instrument as well as the many programming commands available to control the instrument over the IEEE-488 bus. Because of the limited amount space available in this guide. many details abourinstrument operation will not be found here. Refer to the Model 194A Instwction Manual for aspects of instrument operation not covered in this guide. This guide describes the following aspects of the Model 194A: l Front panel operation including XY mode. l A description of mathematical functions. * Input and output signal connections. l IEEE-488 programming information, including commands, data and status formats. and exampkprograms for typical COntrOllers. 01989, Keithley Instruments.
