Programming the Status Register System
The Data Questionable Calibration Status Group is used to determine the specific event
that set bit 8 in the Data Questionable Condition Register. The Data Questionable
Calibration Status Group consists of the Data Questionable Calibration Condition
Register, the Data Questionable Calibration Negative Transition Filter, the Data
Questionable Calibration Positive Transition Filter, the Data Questionable Calibration
Event Register, and the Data Questionable Calibration Event Enable Register. The Data
Questionable Calibration Condition Register contains the following bits:
Figure 1-39.
The Data Questionable Calibration Condition Register continuously monitors the
calibration status of the instrument. Condition registers are read-only. To query the
condition register, send the command STATus:QUEStionable:CALibration:CONDition?
The response will be the decimal sum of the bits which are set to 1.
The transition filter specifies which types of bit state changes in the condition register will
set corresponding bits in the event register. The changes may be positive (from 0 to 1) or
negative (from 1 to 0). Send the command
STATus:QUEStionable:CALibration:NTRansition <num> (negative) or
STATus:QUEStionable:CALibration:PTRansition <num> (positive) where <num> is the
sum of the decimal values of the bits you want to enable.
Bit Description
0 A 1 in this bit indicates that the DCFM/DC
ΦM 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 A 1 in this bit indicates that the I/Q calibration routine has failed. An I/Q calibration
failure does not affect the validity of the source output.

14 Unused. These bits are always set to 0.
15 Always Zero (0).
