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.
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).
Data Questionable Calibration Event Register
The Data Questionable Calibration Event Register latches transition events from the
condition register as specified by the transition filters. Event registers are destructive
read-only. Reading data from an event register clears the content of that register.
Table 3-11 Data Questionable Calibration Condition Register Bits
Bit Description
0
DCFM/DCΦM Zero Failure. A 1 in this bit 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 I/Q Calibration Failure. A 1 in this bit indicates that the I/Q modulation calibration
experienced a failure.
2−14 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
Commands:
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.
