Setting Marker Polarity; Controlling Markers In A Waveform Sequence - Agilent Technologies X Series User Manual

Basic Digital Operation (Option 653/655/656/657)
Using Waveform Markers

Setting Marker Polarity

Setting a negative marker polarity inverts the marker signal.
1. In second Arb menu
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
As shown on page 172:
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 Sequence

In a waveform segment, an enabled marker point generates an auxiliary output signal that is routed
to the rear panel EVENT output (described in
N5182B)" on page 13) corresponding to that marker number. For a waveform sequence, you enable or
disable markers on a segment–by–segment basis; this enables you to output markers for some
segments in a sequence, but not for others. Unless you change the sequence marker settings or cycle
the power, the marker setting for the last segment edited in the sequence applies to all segments in
the next sequence that you build. For information on building a waveform sequence, see
Sequence" on page 152.
