SSTatus
SSTatus
Description Queries the Sync STatus for the current DSP measurement.
Syntax MEASure:ORFSpectrum:SSTatus?
Options Returns one of the following states;
’No Error’ | ’ShortBurst’ | ’Level Late’ | ’LevelShort’ |
’FM Error’ | ’Low Level’ | ‘Math Error’ | ’RF Ovrload’.
The message return priority (highest to lowest) is as follows:
• Math Error
• RF Ovrload | Low Level
• FM Error
• ShortBurst | Level Late | LevelShort
• No Error
The above defined as;
• ShortBurst - amplitude envelope not long enough for the selected burst length.
• RF Ovrload - the DSP Analyzer sampler hardware overloaded during sampling.
• FM Error - at least one FM error was detected during the Midamble (or User Defined
Sync Pattern) portion of the selected burst (only possible for MSYN:SYNC:MODE
’MIDAMBLE’)
• Level Late - amplitude of the burst did not rise until after the first few bits were
received.
• Level Short - amplitude of the burst fell before the last few bits were received.
• Low Level - DSP Analyzer RF level never got high enough to make a valid
measurement.
• Math Error - DSP Analyzer math-related error occurred.
• No Error - no error occurred in synchronizing to the selected burst
