Questionable Register
Questionable Condition
:STATus:QUEStionable:CONDition?
Returns the decimal value of the sum of the bits in the Questionable Condition register.
The data in this register is continuously updated and reflects the current conditions.
Key Type: There is no equivalent front-panel key.
Questionable Enable
:STATus:QUEStionable:ENABle <number>
:STATus:QUEStionable:ENABle?
Determines which bits in the Questionable Event register will set the Questionable Status
Summary bit (bit3) in the Status Byte Register. The variable <number> is the sum of the
decimal values of the bits you want to enable.
Key Type: There is no equivalent front-panel key.
Factory Preset: 0
Range: 0 to 32767
Questionable Event Query
:STATus:QUEStionable[:EVENt]?
Returns the decimal value of the sum of the bits in the Questionable Event register.
The register requires that the associated 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 register is cleared.
Key Type: There is no equivalent front-panel key.
NOTE
The preset condition is all bits in this enable register set to 0. To have any Questionable
Events reported to the Status Byte Register, one 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 may have made the test
results invalid. If it is equal to 0, this indicates that no hardware problem or measurement
problem was detected by the N8201A.
