ESG Family Signal Generators Programming Commands and Examples
:STATus Subsystem
Data Questionable Modulation Status Group Enable
:STATus:QUEStionable:MODulation:ENABle <num>
:STATus:QUEStionable:MODulation:ENABle?
This command determines what bits in the Data Questionable Modulation Status Group
Event Register will set the Data Questionable Modulation Summary bit (bit 7) 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 Modulation Status Group Event Register Query
:STATus:QUEStionable:MODulation[:EVENt]?
This command returns the decimal value of the sum of the bits in the Data Questionable
Modulation Event Register. For example, if the External 1 AC modulation is selected with
no modulation connected, a Modulation 1 Undermod condition exists (bit 0), then a value of
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.
Data Questionable Modulation Status Negative Transition Filter
Register Enable
:STATus:QUEStionable:MODulation:NTRansition <num>
:STATus:QUEStionable:MODulation:NTRansition?
This command determines what bits in the Data Questionable Modulation Status Group
Condition Register will set the corresponding bit in the Data Questionable Modulation
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 Modulation Status Positive Transition Filter
Register Enable
:STATus:QUEStionable:MODulation:PTRansition <num>
:STATus:QUEStionable:MODulation:PTRansition?
This command determines what bits in the Data Questionable Modulation Status Group
Condition Register will set the corresponding bit in the Data Questionable Modulation
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 Power Status Group Condition Register Query
:STATus:QUEStionable:POWer:CONDition?
This command returns the decimal value of the sum of the bits in the Data Questionable
Power Condition Register. For example, if the RF output signal is unleveled (bit 1), then a
value of 2 is returned. Note that the data in this register is continuously updated and
reflects the current conditions.
