Bit No. Meaning
0 OVEN COLD
This bit is set if the reference oscillator has not yet attained its operating temperature. "OCXO"
is displayed.
1 LO UNLocked
This bit is set if the local oscillator no longer locks. "LOUNL" is displayed.
2 to 7 Unused
8 EXTernalREFerence
This bit is set if you have selected an external reference oscillator but did not connect a useable
external reference source.
In that case the synthesizer can not lock. The frequency in all probability is not accurate.
9 to 14 Unused
15 This bit is always 0.
STATus:QUEStionable:LIMit Register
The STATus:QUEStionable:LIMit register contains information about the results of a
limit check when you are working with limit lines.
The number of LIMit registers depends on the number of measurement windows avail-
able in any operating mode.
You can read out the register with
STATus:QUEStionable:LIMit<n>:CONDition?
or
STATus:QUEStionable:LIMit<n>[:EVENt]?
