Questionable Frequency Enable
:STATus:QUEStionable:FREQuency:ENABle <number>
:STATus:QUEStionable:FREQuency:ENABle?
This command determines what bits in the Questionable Frequency
Condition Register will set bits in the Questionable Frequency Event
register, which also sets the Frequency Summary bit (bit 5) in the
Questionable Register. The variable <number> is the sum of the
decimal values of the bits you want to enable.

Range: 0 to 32767
Questionable Frequency Event Query
:STATus:QUEStionable:FREQuency[:EVENt]?
This query returns the decimal value of the sum of the bits in the
Questionable Frequency Event register.
NOTE The register requires that the associated PTR or NTR filters be set
before a condition register bit can set a bit in the event register.
The data in this register is latched until it is queried. Once queried, the
register is cleared.
Questionable Frequency Negative Transition
:STATus:QUEStionable:FREQuency:NTRansition <number>
:STATus:QUEStionable:FREQuency:NTRansition?
This command determines what bits in the Questionable Frequency
Condition register will set the corresponding bit in the Questionable
Frequency Event register when the condition register bit has a negative
transition (1 to 0). The variable <number> is the sum of the decimal
values of the bits that you want to enable.
Factory Preset
and *RST: 0
Range: 0 to 32767
