Data Questionable Frequency Condition Register
The Data Questionable Frequency Condition Register continuously monitors the hardware
and firmware status of the signal generator. Condition registers are read-only.
Data Questionable Frequency Transition Filters (negative and positive)
Specifies which types of bit state changes in the condition register set corresponding bits in
the event register. Changes can be positive (0 to 1) or negative (1 to 0).

Bit Description
0 Synth. Unlocked. A 1 in this bit indicates that the synthesizer is unlocked.
1 10 MHz Ref Unlocked. A 1 in this bit indicates that the 10 MHz reference signal is
unlocked.
2 1 Ghz Ref Unlocked. A 1 in this bit indicates that the 1 Ghz reference signal is unlocked.

Query: STATus:QUEStionable:FREQuency:CONDition?
Response: The decimal sum of the bits set to 1
Commands:
STATus:QUEStionable:FREQuency:NTRansition <value> (negative transition)
or STATus:QUEStionable:FREQuency:PTRansition <value> (positive
transition) where <value> is the sum of the decimal values of the bits you want
to enable.
