ESG Family Signal Generators Programming Commands and Examples
:STATus Subsystem
Data Questionable Status Group Event Register Query
:STATus:QUEStionable[:EVENt]?
This command returns the decimal value of the sum of the bits in the Data Questionable
Event Register. For example, if the instrument has just been connected to line power and
the Reference Oscillator Oven (ESG-AP, ESG-DP, and Option 1E5 only) is cold (bit 4), then
a value of 16 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 Status Negative Transition Filter Register
Enable
:STATus:QUEStionable:NTRansition <num>
:STATus:QUEStionable:NTRansition?
This command determines what bits in the Data Questionable Status Group Condition
Register will set the corresponding bit in the Data Questionable 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.
Standard Operation Status Group Condition Register Query
:STATus:OPERation:CONDition?
This command returns the decimal value of the sum of the bits in the Standard Operation
Status Group Event Register. For example, if a sweep is in progress (bit 3), then the value
8 is returned.
Standard Operation Status Group Enable
:STATus:OPERation:ENAble <num>
:STATus:OPERation:ENAble?
This command determines what bits in the Standard Operation Status Group Event
Register will set the Standard Operation Status Group Summary bit (bit 7) in the Status
Byte Register. The variable <num> is the sum of the decimal values of the bits you want to
enable.
Standard Operation Status Group Event Register Query
:STATus:OPERation[:EVENt]?
This command returns the decimal value of the sum of the bits in the Standard Operation
Event Register. For example, if a sweep is in progress (bit 3), then the value 8 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. Also note that the data in the
register is latched until it is queried. Once queried, the data is cleared.
