:STATus Subsystem
Data Questionable BERT Status Negative Transition Filter Register
Enable
:STATus:QUEStionable:BERT:NTRansition <num>
:STATus:QUEStionable:BERT:NTRansition?
This command determines what bits in the Data Questionable BERT Status Group
Condition Register will set the corresponding bit in the Data Questionable BERT Status
Group Event Register when that bit has a negative transition (1 to 0). The variable <num>
is the sum of the decimal values of the bits that you want to enable.
Data Questionable BERT Status Positive Transition Filter Register
Enable
:STATus:QUEStionable:BERT:PTRansition <num>
:STATus:QUEStionable:BERT:PTRansition?
This command determines what bits in the Data Questionable BERT Status Group
Condition Register will set the corresponding bit in the Data Questionable BERT Status
Group Event Register when that bit has a positive transition (0 to 1). The variable <num> is
the sum of the decimal values of the bits that you want to enable.
Data Questionable Calibration Status Group Condition Register
Query
:STATus:QUEStionable:CALibration:CONDition?
This command returns the decimal value of the sum of the bits in the Data Questionable
Calibration Condition Register. For example, if the DCFM or DC
ΦM zero calibration fails
(bit 0), then a value of 1 is returned. Note that the data in this register is continuously
updated and reflects the current conditions.
Data Questionable Calibration Status Group Enable
:STATus:QUEStionable:CALibration:ENAble <num>
:STATus:QUEStionable:CALibration:ENAble?
This command determines what bits in the Data Questionable Calibration Status Group
Event Register will set the Data Questionable Calibration Summary bit (bit 8) in the Data
Questionable Status Group Condition Register. The variable <num> is the sum of the
decimal values of the bits you want to enable.
Data Questionable Calibration Status Group Event Register Query
:STATus:QUEStionable:CALibration[:EVENt]?
This command returns the decimal value of the sum of the bits in the Data Questionable
Calibration Event Register. For example, if the DCFM or DC
ΦM zero calibration has failed
(bit 0), then a 1 is returned. Note that the register requires that the equivalent PTR or
NTR filters be set before a condition register bit can set a bit in the Event register. Note
also that the data in this register is latched until it is queried. Once queried, the data is
cleared.
