Limit commands
Table 12-1 summarizes remote commands to control limit testing parameters,
while Table 12-2 summarizes commands to control the Digital I/O port bit parame-
ters for limit testing. See Section 18, “CALCulate2” and “SOURce2,” for more
details on these commands.
NOTE The Model 2401 does not use the digital output lines of the Digital I/O
port and does not have a component handler interface. The commands
in
Table 12-2 and Table 12-3 are not valid for the Model 2401 and will
cause undefined header errors.
NOTE For instruments with the contact check option, see Appendix F for more
information.
