COMMAND :STATus:QUEStionable:ENABle . . . <non-decimal_numeric> | <NRf>
Sets or queries the Questionable Data Event Status Enable Register.
RANGE The range of the <non-decimal numeric> or <NRf> parameter is
0 to 32,767.
QUERY RESPONSE Numeric data transferred as ASCII bytes in <NR1> format.
COMMENTS • The parameter and the query response value, when rounded to an
integer value and expressed in base 2 (binary), represent the bit values
of the Questionable Data Event Status Enable Register.
• The value of unused bits is zero when queried and ignored when set.
• This register is used to enable a single or inclusive OR group of
Questionable Data Event Status Register events to be summarized in
the Status Byte Register (bit 3).
• At power-on and :STAT:PRES, the Questionable Data Event Status
Enable Register is cleared (value is 0).
• This value is unaffected by *RST, *CLS, and *SAV/*RCL.

COMMAND :STATus:QUEStionable[:EVENt]?
Queries the status of the Questionable Data Event Status Register.
QUERY RESPONSE • Numeric data transferred as ASCII bytes in <NR1> format.
• Range is 0 to 32,767.
• The query response value is an integer formed by the binary weighting
of bits. The value of unused bits is zero.
COMMENTS • Each event bit in the Questionable Data Event Status Register
corresponds to a specific condition bit in the Questionable Data
Condition Status Register; this allows the Questionable Data Status
Register to detect changes in conditions.
• An event becomes TRUE when the associated condition makes the
transition specified by the transition filters.
