Remote Operation

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.
