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.
