DPX Trace Processing
The +Peak, -Peak, and Average traces can be processed to display in different ways. The Function setting
controls trace processing.
Hold - Displays the value in the trace record for each display point. Each new trace display point is
compared to the previous maximum value and the greater value is retained for display and subsequent
comparisons. Available for traces using +Peak or -Peak detection.
Normal - Displays the trace record for each display point without additional processing. Available
for all detection selections.
Average - Default setting for the Average. Multiple traces are averaged together to generate the
displayed trace. There is one vertical value for each underlying frequency data point. Once the
speci
fi ed number of traces have been acquired and averaged to generate the displayed trace, each new
trace takes the place of the oldest trace in the calculation. The Count setting speci fi es how many
traces are averaged. Available for traces using Average detection.
Trace averaging uses the exponential method. If Count = 10, the newest trace’s contribution to the
averaged trace is 10%. When Count is not checked, the algorithm assumes the maximum number of
traces contributing to the average is
.
Saving Traces
To save a trace for later analysis:
1. Select the Save Trace As button. This displays the Save As dialog box.
2. Type a name for the saved trace and click Save .
Recalling Traces
You can recall a previously saved trace for comparison to a live trace. First, specify a trace for recall and
second, enable Show Recalled Trace.
