STATus:QUEStionable Subsection
Questionable Enable
:STATus:QUEStionable:ENABle <integer>
:STATus:QUEStionable:ENABle?
This command determines which bits in the Questionable Condition Register will
set bits in the Questionable Event register, which also sets the Questionable Status
Summary bit (bit3) in the Status Byte Register. The variable <integer> is the sum
of the decimal values of the bits you want to enable.
NOTE The preset condition is to have all bits in this enable register set to 0. To have any
Questionable Events reported to the Status Byte Register, 1 or more bits need to be
set to 1. The Status Byte Event Register should be queried after each measurement
to check the Questionable Status Summary (bit 3). If it is equal to 1, a condition
during the test made the test results invalid. If it is equal to 0, this indicates that no
hardware problem or measurement problem was detected by the analyzer.

Questionable Event Query
:STATus:QUEStionable[:EVENt]?
This query returns the decimal value of the sum of the bits in the Questionable
Event register.
NOTE The register requires that the equivalent PTR or NTR filters be set before a
condition register bit can set a bit in the event register.
The data in this register is latched until it is queried. Once queried, the data is
cleared.
Questionable Frequency Condition
:STATus:QUEStionable:FREQuency:CONDition?
This query returns the decimal value of the sum of the bits in the Questionable
Frequency Condition register.
NOTE The data in this register is continuously updated and reflects the current conditions.
