Table 10-7: Meaning of the bits used in the STATus:QUEStionable register
Bit No. Meaning
0 - 1 Unused
2 TIMe
This bit is set if a time error occurs in any of the active channels.
The STATus:QUEStionable:TIMe Register provides more information on the error type.
3 POWer
This bit is set if the measured power level in any of the active channels is questionable.
The STATus:QUEStionable:POWer Register provides more information on the error type.
4 TEMPerature
This bit is set if the temperature is questionable.
5 FREQuency
This bit is set if there is anything wrong with the frequency of the local oscillator or the reference
frequency in any of the active channels.
The STATus:QUEStionable:FREQuency Register provides more information on the error type.
6 - 7 Unused
8 CALibration
This bit is set if the R&S FSW is unaligned ("UNCAL" display)
9 LIMit (device-specific)
This bit is set if a limit value is violated in any of the active channels in any window.
The STATus:QUEStionable:LIMit Register provides more information on the error type.
10 LMARgin (device-specific)
This bit is set if a margin is violated in any of the active channels in any window.
The STATus:QUEStionable:LMARgin Register provides more information on the error type.
11 SYNC (device-specific)
This bit is set if the R&S FSW is not synchronized to the signal that is applied.
The R&S FSW is not synchronized if:
●
it cannot synchronize to midamble during a measurement or premeasurement
●
it cannot find a burst during a measurement or premeasurement
●
the results deviate too much from the expected value during premeasurements
12 ACPLimit (device-specific)
This bit is set if a limit during ACLR measurements is violated in any of the active channels.
The STATus:QUEStionable:ACPLimit Register provides more information on the error type.
13 Unused
14 Digital I/Q (device-specific)
This bit is set if a connection error occurs at the Digital Baseband Interface (R&S FSW-B17)
For details see the R&S FSW I/Q Analyzer User Manual.
15 This bit is always 0.
