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
