:STATus Subsystem
Data Questionable Frequency Status Group Enable
:STATus:QUEStionable:FREQuency:ENAble <num>
:STATus:QUEStionable:FREQuency:ENAble?
This command determines what bits in the Data Questionable Frequency Status Group
Event Register will set the Data Questionable Frequency Summary bit (bit 5) 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 Frequency Status Group Event Register Query
:STATus:QUEStionable:FREQuency[:EVENt]?
This command returns the decimal value of the sum of the bits in the Data Questionable
Frequency Event Register. For example, if the 1 GHz internal reference clock is unlocked
(bit 2), then a value of 4 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.
Data Questionable Frequency Status Negative Transition Filter
Register Enable
:STATus:QUEStionable:FREQuency:NTRansition <num>
:STATus:QUEStionable:FREQuency:NTRansition?
This command determines what bits in the Data Questionable Frequency Status Group
Condition Register will set the corresponding bit in the Data Questionable Frequency
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 Frequency Status Positive Transition Filter
Register Enable
:STATus:QUEStionable:FREQuency:PTRansition <num>
:STATus:QUEStionable:FREQuency:PTRansition ?
This command determines what bits in the Data Questionable Frequency Status Group
Condition Register will set the corresponding bit in the Data Questionable Frequency
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 Modulation Status Group Condition Register
Query
:STATus:QUEStionable:MODulation:CONDition?
This command returns the decimal value of the sum of the bits in the Data Questionable
Modulation Condition Register. Note that the data in this register is continuously updated
and reflects the current conditions.
