Characteristic
Description
Vertical Scale Factor
Units
1 dB to 10 dB in 1 dB increments
Display Modes
Normal: updates display with each new result
Max Hold: updates displayed point only if new point > old point
Min Hold: updates displayed point only if new point < old point
Max/Min Hold: displays a bar between Max Hold and Min Hold
Average: displays average of N (speci
fi
ed by user) results
Reference information: Average is calculated as follows: The last N values are saved in memory;
when a new result is available, the earliest result of the N stored values is discarded, the new
average is calculated from the stored values. If the number of results is less than N, then all of
the results are averaged together.
