STATus:QUEStionable:DIQ register
The STATus:QUEStionable:DIQ register is used for digital I/Q data from the
optional Digital Baseband Interface (R&S FSW-B17) and is described in the R&S FSW
I/Q Analyzer and I/Q Input User Manual.
STATus:QUEStionable:SYNC register
The STATus:QUEStionable:SYNC register is used by the R&S FSW applications
and is described in the individual sections (manuals) for each application.

Status Byte (STB) and Service Request Enable Register (SRE)
The STatus Byte (STB) is already defined in IEEE 488.2. It provides a rough over-
view of the instrument status by collecting the pieces of information of the lower regis-
ters. A special feature is that bit 6 acts as the sum bit of the remaining bits of the status
byte.
The STB can thus be compared with the CONDition part of an SCPI register and
assumes the highest level within the SCPI hierarchy.
The STB is read using the command *STB? or a serial poll.
The STatus Byte (STB) is linked to the Service Request Enable (SRE) register.
Each bit of the STB is assigned a bit in the SRE. Bit 6 of the SRE is ignored. If a bit is
set in the SRE and the associated bit in the STB changes from 0 to 1, a service
request (SRQ) is generated. The SRE can be set using the command *SRE and read
using the command *SRE?.
