The Model 2000 can be configured to accept device-dependent commands of the Keithley
Models 196/199. The commands to control the Model 2000 with the 196/199 language are pro-
vided in Table D-1.
Since the architecture of the Model 2000 differs from that of the 196/199, some commands
are different or cannot be used. Commands such as function (offset-compensated ohms, AC cur-
rent dB), range, analog and digital filter, rate, calibration, factory defaults, and self-test do not
map one-for-one. Also note that the Model 2000 does not have the speed characteristics of the
Models 196/199. Other commands of the Model 2000 have been added to the 196/199 command
set, such as frequency, temperature, and scanning. Refer to the appropriate manual for further
details.
CAUTION The 196/199 language is intended to be used only over the IEEE-488 bus.
Using front panel controls in conjunction with this language may cause
erratic operation. In this case, results cannot be guaranteed.
