Markers

Markers can help you determine if the waveform that is produced is correct. We have provided three markers, each with different characteristics. From the GUI, you can specify when and for how long each marker will appear, but if you define your own waveforms, you can have any of the markers appear numerous times.

The marker settings are in the Waveform panel, just below the Data Length box.

Position specifies the data point where you would like to start the marker. Width specifies the number of data points you would like the marker to be active.
The "P" polarity checkbox is only available for Marker 2 and allows you to select active low marker signals (when unchecked).
The "E" enable checkbox is only available for Marker 2 and Marker 3 and is used for turning on those marker outputs.

Marker 1 is 1.8 V TTL (rail-to-rail) logic level while Marker 2 and Marker 3 are both 3.3 V LVTTL (rail-to-rail) logic level. Marker 1 has less delay than either Marker 2 or Marker 3. For details about the three available markers, please see the Parameters page of the Operation Details section.
