Indicates that at least one bit is set in the Questionable
Hardware Condition register.
:QUEStionable:ENABle?
Description
Queries the SCPI Questionable Enable Register.
Query Response
An integer which is the sum of the bit values for all bits in the register
that are set.
Examples
:STAT:QUES:ENAB?
:QUEStionable:ENABle <integer>
Description
Used to set and clear bits in the SCPI Questionable Enable Register.
This register contains bits that are used to mask one or more
conditions indicated in the Questionable Status Register. Setting a bit
causes that condition to be masked so that, even if the condition is
true, its associated bit will not get set in the Questionable Status
Register. The Questionable Enable Register has the same format as
the Questionable Status Register. See table above.
Examples
:STAT:QUES:ENAB 1
:STAT:QUES:ENAB 1024
SYSTem Subsystem
The SYSTem subsystem { XE “Commands:SYSTem” } supplies information and status about
the SCPI command parser.
