Up to 6 ranges may be specified using one :ENABle command, representing the 6 ranges of errors/events. The ranges are
then separated from each other by Program Data Separators (comma). The entire expression must be enclosed in
parentheses(...).
Command Type: Setting or Query

Response: (NRf|<event range>[{,[NRf|event range>]})
4.13.5.4 Questionable Status
The Questionable status data structure is used to alert the user to instrument conditions that affect the signal quality. Two
types of conditions are defined in the AWG, and these are:
1) Frequency - Trigger rate conflict, and
2) Output overload condition.
Each condition is reported separately for each channel. Thus, a total of four conditions may be reported.
The data structure is comprised of five 16-Bit registers. Each bit represents a different status condition. In the AWG, bits 9
and 11 are used as follows:
Bit 9: Frequency - trigger rate conflict.
Bit 11: Output overload.
The existence of these conditions is indicated in the CONDition register. Bit 3 of the status byte is used to indicate the
occurrence of a questionable status condition. The conditions cause this bit to be set depending on the values of the other four
registers.
The positive transition filter enables a bit in the event register to be set when a condition changes from false to true. The
negative transition register enables a bit in the event register to be set when a condition changes from true to false. In order
for the bit in the event register to be set, the corresponding bit in the transition register must be set.
Bit 3 in the status byte will be set if a bit in the event register is set while the corresponding bit in the enable register is set.
