STATus:QUEStionable Register
The STATus:QUEStionable register contains information on instrument states that do
not meet the specifications.
The STAT:QUES:SYNC register is used by the applications and is thus described in the
individual applications' User Manuals.
You can read out the register with STAT:QUES:COND or STAT:QUES:EVEN.
The STATus:QUEStionable register "sums up" the information from all subregisters
(e.g. bit 2 sums up the information for all STATus:QUEStionable:TIMe registers).
For some subregisters, there may be separate registers for each active channel. Thus,
if a status bit in the STATus:QUEStionable register indicates an error, the error may
have occurred in any of the channel-specific subregisters. In this case, you must check
the subregister of each channel to determine which channel caused the error. By
default, querying the status of a subregister always returns the result for the currently
selected channel.
