Status Groups
Data Questionable Calibration Condition Register
The Data Questionable Calibration Condition Register continuously monitors the calibration status of
the signal generator. Condition registers are read only.
Table 4-16 Data Questionable Calibration Condition Register Bits
Bit Description
a I/Q Calibration Failure. A 1 in this bit position indicates that the I/Q modulation calibration experienced a failure.
0
b
1 DCFM/DCΦM Zero Failure. A 1 in this bit position indicates that the DCFM/DCΦM zero calibration routine has
failed. This is a critical error. The output of the source has no validity until the condition of this bit is 0.
2−14 Unused. These bits are always set to 0.
15 Always 0.
a
In the N5161A/81A, E4428C, E8257D, E8663B, and the E8663D, this bit is set to 0.
b
In the N5161A/81A and N5162A/82A, this bit is set to 0.
Table 4-17 Data Questionable Calibration Condition Register Bits
Bit Description
0
DCFM/DCΦM Zero Failure. A 1 in this bit position indicates that the DCFM/DCΦM zero calibration routine has
failed. This is a critical error. The output of the source has no validity until the condition of this bit is 0.
1−14 Unused. These bits are always set to 0.
15 Always 0.
Query:
STATus:QUEStionable:CALibration:CONDition?
Response: The decimal sum of the bits set to 1.
Data Questionable Calibration Transition Filters (negative and positive)
The Data Questionable Calibration Transition Filters specify which type of bit state changes in the
condition register set corresponding bits in the event register. Changes can be positive (0 to 1) or
negative (1 to 0).

Queries:
Data Questionable Calibration Event Register
The Data Questionable Calibration Event Register latches transition events from the condition register

STATus:QUEStionable:CALibration:NTRansition <value> (negative transition), or
STATus:QUEStionable:CALibration:PTRansition <value> (positive transition), where <value> is
the sum of the decimal values of the bits you want to enable.
