:QUEStionable Commands

110
The Questionable Data register group provides information about the
quality or integrity of the instrument. Any or all of these conditions can be
reported to the Questionable Data summary bit through the enable
register.
The following commands access the questionable status group.
:STATus:QUEStionable[:EVENt]?
Reads the event register in the questionable status group. It's a read-only
register. Once a bit is set, it remains set until cleared by this command or
the *CLS command. A query of the register returns a decimal value which
corresponds to the binary-weighted sum of all bits set in the register.
:STATus:QUEStionable:CONDition?
Reads the condition register in the questionable status group. It's a
read-only register and bits are not cleared when you read the register. A
query of the register returns a decimal value which corresponds to the
binary-weighted sum of all bits set in the register.
:STATus:QUEStionable:ENABle[?]
Sets or queries the enable register in the questionable status group. The
selected bits are then reported to the Status Byte. A *CLS will not clear
the enable register but it does clear all bits in the event register. To enable
bits in the enable register, you must write a decimal value which
corresponds to the binary-weighted sum of the bits you wish to enable in
the register.
:STATus:QUEStionable:NTRansition[?]
Sets or queries the negative-transition register in the questionable status
group. A negative transition filter allows an event to be reported when a
condition changes from true to false. Setting both positive/negative filters
true allows an event to be reported anytime the condition changes.
Clearing both filters disable event reporting. The contents of transition
filters are unchanged by *CLS and *RST.
:STATus:QUEStionable:PTRansition[?]
Set or queries the positive-transition register in the questionable status
group. A positive transition filter allows an event to be reported when a
condition changes from false to true. Setting both positive/negative filters
