SR785 Dynamic Signal Analyzer
Exceedance Statistics Menu
The Exceedance Statistics menu calculates exceedance centile statistics from Octave and
FFT measurements stored in the waterfall buffer. Exceedence calculation is only
available when the waterfall buffer has been saved using the Active Measurement Only
Save Option.
Start Index
Set the starting record in the waterfall buffer for the calculation of L
n
(exceedance
centile). The analysis starts at the start index and includes all records through the stop
index.
Index 0 is the most recent record, larger indexes are older.
The total number of records currently stored and available in the waterfall buffer is
displayed in the Vertical Scale Bar. The Start Index should not exceed the total number
of records in the buffer.
Both displays use the same Start Index.
Command: ESTR (?) {i}
Stop Index
Set the stop record in the waterfall buffer for the calculation of L
n
(exceedance centile).
The analysis starts at the start index and includes all records through the stop index.
Index 0 is the most recent record, larger indexes are older.
The total number of records currently stored and available in the waterfall buffer is
displayed in the Vertical Scale Bar. The Stop Index should not exceed the total number
of records in the buffer.
Both displays use the same Stop Index.
