Fault Events - which
must be enabled by
the Protection
Enable Register
before they are
recorded in the fault
register.
Protection Condition Register –
readable using
STAT:PROT:COND? query command
The SESER (Standard Event Status Enable Register). This
register is read using the *ESE? SCPI query command. This
register is written to using the *ESE <value> command. A "1" in
the appropriate bit location enables that corresponding bit from
the SESR to pass through to the input of the OR gate to be
included in the SESR summary bit (bit 5) in the SCPI Status Byte.

The SESR (Standard Event Service Register). Masking does not prevent events from
setting bits in the SESR. This facilitates polling as a means of detecting these events,
since the SESR can be polled (read) using the *ESR? command, irrespective of the bits
set or not set in the Standard Event Status Enable Register.

The Protection Enable Register. Readable using the STAT:PROT:ENAB? query
command. Writable using the STAT:PROT:ENAB <value> command. Used to select
what fault events could set a bit in the Fault Register. Certain faults can occur even
if they are not enabled. This is because the Protection Enable Register merely filters
which events are allowed to affect the Fault Register, not whether those events can

The Service Request Enable Register (SRER).
Used to enable which Status Byte bits can affect the
service request bit. *SRE? reads. *SRE <value> writes.
