Figure 8-15 Sample data detail display
The following trace adjustments and settings are available:
• Profile—switches the trace for the selected channel on and off.
• Channel—opens a dialog box that allows you to configure the trace setup (see
Trace Controls
on page 81 for details).
• Probe—opens a dialog box that allows you to select the type of test probe being used.
• Peak Detect—maximizes the signal sampling rate in order to capture fast events, such as
spikes, glitches and other anomalies, that may normally be undetected.
• Filter—smooths out the trace when the signal is disrupted by noise or other interference.
• Inverted—switches the polarity of the displayed signal.
• Coupling AC—subtracts the average value of the waveform by blocking the DC portion of an
input signal to amplify the AC portion. This makes small variations in the trace visible.
• Scale—opens a dialog box that allows you to select the scale, which is the total value
displayed on the vertical axis of the display.
• Sweep—the current sweep setting is shown in white at the end of the scale list, selecting
opens a dialog box that adjusts the sweep (see
Sweep Controls on page 83 for details).
• Slope—only active when a trigger is set, indicates whether the trigger is set to activate on the
rising or falling slope of the trace. Tapping the slope icon switches the slope. The white dash
