Figure 10-2: Graphical overview of the R&S
FSPN 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.
●
IST, PPE
The
IST
flag ("Individual STatus"), like the
SRQ
, combines the entire instrument
status in a single bit. The
PPE
fulfills the same function for the
IST
flag as the
SRE
for the service request.
