Programming the Status Register System
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.
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 4-7 Data Questionable Calibration Condition Register Bits
Bit Description
0 DCFM Calibration Failure. A 1 in this bit position indicates that the DCFM 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 position 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.
