SCPI Preset Status
Configures the status data structures to ensure that certain events are
reported at a higher level through the status-reporting mechanism. These
events are summarized in the mandatory structures, the Operation Status
Register and Questionable Status Register.
The PRESet command affects only the enable registers and the transition
filter registers of the status data structures. PRESet does not clear any of
the event registers or any item from the error/event queue. The *CLS
command is used to clear all event registers and queues in the device
status-reporting mechanism.
For the device-dependent status data structures, the PRESet command
sets the enable register to all 1s and the transition filter register to report
only positive transitions. For the SCPI mandatory status data structures,
the PRESet command sets the transition filter registers to recognize only
positive transitions and sets the enable register to 0s. The following will
not be affected by this command: Service Request Enable Register,
Parallel Poll Enable Register, the memory register associated with the
*SAV command, the power supply address, Output Queue, and the
power-on-status-clear flag setting.
