Manual and Track Waveform modes can be used on waveforms that are displayed
on the analog input channels (including math functions).
Binary and Hex modes apply to digital signals.
In Hex and Binary modes, a level can be displayed as 1 (higher than trigger
level), 0 (lower than trigger level), indeterminate state (-), or X (don't care).
In Binary mode, X is displayed if the channel is turned off.
In Hex mode, the channel is interpreted as 0 if turned off.
5 Select Source (or X1 Source, X2 Source in the Track Waveform mode); then, select
the input source for marker values.
6 Select the X1, X2, Y1, and/or Y2 check boxes to enable or disable individual
markers and the fields used to specify their locations.
7 Select the Show Readout check box to enable or disable the display of marker
value annotations.
8 Select the marker(s) to be adjusted:
• Push the vertical Markers knob to cycle through the selection of Y1, Y2, or
both Y1 Y2 (to be adjusted as a pair).
You can also make these selections in the Markers dialog box using the
Selected Y drop-down list.
• Push the horizontal Markers knob to cycle through the selection of X1, X2, or
both X1 X2 (to be adjusted as a pair).
You can also make these selections in the Markers dialog box using the
Selected X drop-down list.
Selecting pairs of markers lets you adjust them both at the same time, while the
delta value remains the same. This can be useful, for example, for checking
pulse width variations in a pulse train.
The currently selected marker(s) are highlighted on the display and in the
Markers dialog box.
9 Adjust the the selected marker(s):
• Turn the vertical Markers knob to move the selected marker(s) up or down
on the screen.
You can also select the Y1 and Y2 fields in the Markers dialog box and use
the associated controls to adjust the vertical markers.
• Turn the horizontal Markers knob to move the selected marker(s) left or right
on the screen.
You can also select the X1 and X2 fields in the Markers dialog box and use
the associated controls to adjust the horizontal markers.
You can also select and position markers by dragging them on the touchscreen.
