+Peak – Each point on the trace is the result of detecting the positive peak value present in the set of
IQ samples available to that trace point.
-Peak – Each point on the trace is the result of detecting the negative peak value present in the set of
IQ samples available to that trace point.
Avg (VRMS) [Average V
RMS
] – Each point on the trace is the result of determining the RMS Voltage
value for all of the IQ samples available to the trace point. When displayed in either linear (Volts,
Watts) or Log (dB, dBm), the correct RMS value results. When the averaging function is applied to a
trace, the averaging is performed on the linear (Voltage) values, resulting in the correct average
for RMS values.
Trace Processing
Traces can be processed to display in different ways. The Detection setting controls trace decimation,
when needed. When the trace points each cover more than one sample data point, the vertical results
values for multiple data points are combined into each trace point. Each trace point ends up with a single
vertical value.
Average - Each trace point is computed by averaging together the multiple results points it represents.
+Peak - Each trace point represents the highest vertical value among the results it includes.
–Peak - Each trace point represents the lowest vertical value among the results it includes.
Saving Traces
To save a trace for later analysis:
1. Select the Save Trace As button. This displays the Save As dialog box.
2. Navigate to the desired folder or use the default.
3. Type a name for the saved trace and click Save .
