Average Operator

The Average math operator stores (in the function) the average waveform value acquired in each time bucket in the source. To set the number of time buckets included in the running average, click on the operator icon. This opens the Average Setup dialog. The default number of averages is 16.

The average value results are recalculated when any of the following occurs:

• Time base scale, position, or reference is changed
• Channel scale or channel offset is changed
• Trigger definition is changed
• Record length is changed
• Additional data is stored to a waveform memory that is used as part of a function
• Clear on the menu bar is clicked

The operator's Display Setup configures the manner in which the resulting waveform is displayed including both vertical and horizontal scaling. Track selection to allows the output waveform to track changes to the scaling of the input waveform. Track is the default setting. In addition, you can turn the waveform's display off or on and select the color of the trace.

Use the Name button to give the displayed waveform a custom identifying name which is show in the Signals area on the display graticule and in the Signals palette. Custom names are very helpful for screen captures or when multiple waveforms are displayed.

The Graph Window is available when multiple waveform content windows are used.

Use the Signal Type's Track selection to allows the waveform type (NRZ or PAM4) to track the input waveform's type. Track is the default setting. If input waveform's type cannot be automatically determined, select Manual to specify the waveform type.
