ESG Family Signal Generators Programming Commands and Examples

:STATus Subsystem

The IEEE status subsystem is used to set the controls and the parameters associated with

status conditions within the signal generator.

Status Preset

:STATus:PRESet

This command presets all transition filters, enable registers, and all error/event queue

enable registers.

Data Questionable BERT Status Group Condition Register Query

:STATus:QUEStionable:BERT:CONDition?

This command returns the decimal value of the sum of the bits in the Data Questionable

BERT Condition Register. For example, if no clock signal has not been input for more than

three seconds during the bit error rate measurements (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 BERT Status Group Enable

:STATus:QUEStionable:BERT:ENAble <num>

:STATus:QUEStionable:BERT:ENAble?

This command determines what bits in the Data Questionable BERT Status Group Event

Questionable Status Group Condition Register. The variable <num> is the sum of the

decimal values of the bits you want to enable.

Data Questionable BERT Status Group Event Register Query

:STATus:QUEStionable:BERT[:EVENt]?

This command returns the decimal value of the sum of the bits in the Data Questionable

BERT Event Register. For example, if no clock signal for the bit error rate tests has not

been input for more than three seconds (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.
