The ABORt command forces the trigger system to the idle state. Any
measurement or output sequence in process is aborted as quickly as
does not alter the settings programmed by other
commands, unlike *RST.
cannot be queried.
The IMMediate command provides a one-time override of the normal
downward path in an event-detection state. The instrument must be
in the specified event detection state when IMMediate is received, or
an error is generated and the command has no effect. For example,
the instrument must be in the TRIG state for :TRIGger : IMMediate
to work properly. If the instrument is in the idle state, the command
has no effect, and an error would be generated. IMMediate is an
event command and cannot be queried.
The ODELay command specifies the time between the source
settling and the time the trigger out signal is sent. Specifying
set the specified time as the delay necessary to ensure proper settling.
Sending *RST sets ODELay to an instrument dependent value, usually
The SOURce command selects the trigger source for an
event-detection state. Only one source can be specified at a time,
and all others are ignored. Sending *RST sets SOURce to IMMediate.
The most commonly used sources are:
