Figure C-2: Overview of the status registers hierarchy
●
STB, SRE
The STatus Byte (STB) register and its associated mask register Service Request
Enable (SRE) form the highest level of the status reporting system. The STB pro-
vides a rough overview of the instrument status, collecting the information of the
lower-level registers.
●
ESR, SCPI registers
The STB receives its information from the following registers:
– The Event Status Register (ESR) with the associated mask register standard
Event Status Enable (ESE).
– The STATus:OPERation and STATus:QUEStionable registers which are
defined by SCPI and contain detailed information on the instrument.
