Basic Digital Operation (Option 651/652/654)Using Waveform MarkersSetting Marker PolaritySetting a negative marker polarity inverts the marker signal.1. In second Arb menu (page 160), press Marker Utilities > Marker Polarity.2. For each marker, set the marker polarity as desired.• The default marker polarity is positive.• Each marker polarity is set independently.See also, “Saving Marker Polarity and Routing Settings” on page 156.As shown on page 166:Positive Polarity: On marker points are high (≈ 3.3V).Negative Polarity: On marker points are low (0V).RF blanking always occurs on the low part of the signal regardless of the polarity setting.Controlling Markers in a Waveform SequenceIn a waveform segment, an enabled marker point generates an auxiliary output signal that is routedto the rear panel EVENT output (described in “Rear Panel Overview – N5161A/62A1/81A/82A MXG”on page 15) corresponding to that marker number. For a waveform sequence, you enable or disablemarkers on a segment–by–segment basis; this enables you to output markers for some segments in asequence, but not for others. Unless you change the sequence marker settings or cycle the power, themarker setting for the last segment edited in the sequence applies to all segments in the nextsequence that you build.
