Status Register Commands

In the following sections <status-enable> is a value from 0 to 32767 representing a
15-bit register mask.
SCPI Status
Preset Status
Commands
STATus[<channel>]:PRESet
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.
