STATus Subsystem

STATus Subsystem
The STATus subsystem controls the SCPI-defined Operation and Questionable
Status registers, Standard Event register, and the Status Byte register. Each is
comprised of a condition register, an event register, an enable mask, and
transition filters.
Each status register works as follows: when a condition occurs, the appropriate
bit in the condition register is set or cleared. The contents of the events register
and the enable mask are logically ANDed bit-for-bit; if any bit of the result is set,
the summary bit for that register is set in the status byte. The status byte
summary bit for the Operation status register is bit 7; for the Questionable Signal
status register, bit 3; and for the Standard Event registers is bit 5.

Syntax

STATus
The STATus system contains five registers, two of which are under IEEE 488.2
control: the Event Status Register (*ESE?) and the Status Byte Register (*STB?).
The Operational Status bit (OPR), Service Request bit (RQS), Event Summary bit
(ESB), Message Available bit (MAV) and Questionable Data bit (QUE) in the
Status Byte Register (bits 7, 6, 5, 4 and 3 respectively) can be queried with the
*STB? command. Use the *ESE? command to query the unmask value for the
Keysight E1459A/Z2404B User and SCPI Programming Guide
Transition filters are always set for positive edge transitions.
When an event occurs, the condition is set and the event register
bit is set true. If the event condition is cleared, the event status
register remains set. The event status register is cleared upon
reading that register.
