13 Markers
• ∆Y/∆X
To make marker measurements
1 Connect a signal to the oscilloscope and obtain a stable display.
2 To enable markers:
• Press the front panel [Markers] key to enable or disable markers.
• Or, in the Markers dialog box, select On to enable or disable markers.
3 To open the Markers dialog box:
• Choose Measure > Markers... from the main menu.
• When markers are enabled and displayed in the Results area, select the
Edit button in the Markers window.
4 In the Markers dialog box, from the Mode drop-down list, you can select:
• Manual — ∆X, 1/∆X, ∆Y, and ∆Y/∆X values are displayed. ∆X is the difference
between the X1 and X2 markers and ∆Y is the difference between the Y1 and
Y2 markers.
• Track Waveform — As you move a marker horizontally, the vertical amplitude
of the waveform is tracked and measured. The time and voltage positions
are shown for the markers. The vertical (Y) and horizontal (X) differences
between the markers are shown as ∆X and ∆Y values.
• Measure — When measurements are displayed, this mode shows the marker
locations used to make the measurement. When you add a measurement, it
becomes the one that markers are displayed for.
You can change the measurement whose marker locations are displayed by
selecting it in the Measurements results list.
• Binary — Logic levels of displayed waveforms at the current X1 and X2
marker positions are displayed in the Markers results window in binary. The
display is color coded to match the color of the related channel's waveform.
• Hex — Logic levels of displayed waveforms at the current X1 and X2 marker
positions are displayed in the Markers results window in hexadecimal.
