Sync Status
Sync Status
This field displays any errors that occurred while trying to synchronize the
demodulated data. Some screens use this field to display progress during multi-burst
measurement. When the measurement is completed to field returns to its normal
state.
Bad Sync (for
demodulation only)
This message appears if a synchronization error happened since the last
Demodulation Arm (when Adjust Mode is disabled) or since the last change to Trig
Delay (when Adjust Mode is enabled with Demod Arm already selected).
Possible causes of Bad Sync are:
•
Useful bits occurred while power was too low.
•
Demodulation trigger too early or too late.
•
FM (bit) errors found while synchronizing to desired midamble.
•
RF overload.
FM Error
At least one bit error was detected when comparing the measured midamble to the
selected Midamble or User Defined Sync Pattern, (Sync Mode=Midamble only).
Level Late
The amplitude of the burst did not rise until after the first few bits were received.
Level Short
The amplitude of the burst fell before the last few bits were received.
Low Level
The DSP analyzer’s RF level did not rise high enough to make a valid measurement.
No Error
No synchronization error occurred.
RF Ovrload
The measurement hardware overloaded during the measurement. (Increase RF
Analyzer Amplitude setting to correct).
ShortBurst
The amplitude envelope was shorter than the expected burst.
