SCPI Commands for Digital Interfaces
TM-XDOP-01XN
4–43
Status Registers
The Status Register structure is mandatory for SCPI and IEEE 488.2 compliance.
The register bits are defined by the SCPI and IEEE 488.2 standards.
Each status register has a Condition, Event, and Enable register and transition
filters. See “Status Register Commands” on page 4–58 for commands to read or
change their values.
Condition
Register
Transitions of the condition register are automatic and reflect the condition of the
instrument at the moment. Reading a condition register has no effect on the
contents.
Event Register
The event register bits are set automatically to correspond with changes in the
condition register. The rules are dependent on the positive and negative transition
registers. Reading an event register clears it. The *CLS command clears all event
registers.
Enable Register
The enable register enables reporting of the event bits to the summary bit or the
status byte. The contents of the enable register are unchanged by *CLS and *RST.
Transition
Filters
A positive transition filter allows an event to be reported when a condition
changes from false to true. Setting both positive and negative filters to TRUE
allows an event to be reported any time the condition changes. Clearing both
filters disables event reporting.
The contents of transition filters are unchanged by *CLS and *RST.
The status registers maybe be divided into 4 categories, the operation status
registers, the questionable status registers, the standard event status register and
the status byte.
