QUICK REFERENCE GUIDE
The Keithley Model 220 Programmable Current Source and 230 Pro-
grammable Voltage Source are easily interfaced to common con-
trollers using the IEEE-488 bus. These programs will set the current
and voltage values using the following controllers:
HP 85; HP 9825A; HP 98458; APPLE II (APPLE Interface); PET/CBM
2001; TEK 40% IBM PC or XT Personal Computer, E-H 7000 Com-
The programs accept a numeric input from the controller keyboard,
program the Model 220 for autoranging and continuous operation,
and set the instrument output to the values entered. All other
parameters remain unchanged, but may be altered by including
another input string variable. Programming for Model 230 f&flows the
same format with only minor modifications as explained in a note at
the end of each example.
