Keithley 7001 User Manual

IEEE-488 Reference

These action commands are used to bypass the specified layer of the Trigger Model. They are
used when you do not wish to wait for the programmed event. Note from the Trigger Model
(Figure 5-13) that :arm:lay2:imm and :trig:imm also bypass the Delay.
The instrument must be waiting for the appropriate event when the command is sent. Otherwise,
an error will occur and the command will be ignored. When the command is sent, the bypass
will occur and operation will continue on.
Note that :IMMediate is not an instrument setup command. As soon as this command is execut-
ed, it will attempt to bypass the specified trigger model layer.
