4 Programming the Status Register System
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.
2−14 Unused. These bits are always set to 0.
15 Always 0.
Table 12 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.
Table 11 Data Questionable Calibration Condition Register Bits
Bit Description
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.
