6.4.1 Overview of Status Registers
The status registers of the R&S OSP are implemented as shown below.
6.4.2 Contents of the Status Registers
The individual status registers are used to report different classes of instrument states
or errors. The following status registers belong to the general model described in IEEE
488.2:
●
The
Status Byte
(STB) gives a rough overview of the instrument status.
●
The
Event Status Register
(ESR) indicates general instrument states.
6.4.2.1 STB and SRE
The Status Byte (STB) provides a rough overview of the instrument status by collecting
the pieces of information of the lower registers. The STB represents the highest level
within the SCPI hierarchy. A special feature is that bit 6 acts as the summary bit of the
remaining bits of the status byte.
The Status Byte (STB) is linked to the Service Request Enable (SRE) register on a bit-
by-bit basis.
The STB is indicating the current instrument state.
