5 Measurements and Math Functions
178 InfiniiVision 7000B Series Oscilloscopes User’s Guide
When active, the Y1 and Y2 cursor values for the selected waveform
source are displayed in the softkey menu area.
The difference between Y1 and Y2 (Y) is displayed on the dedicated line
above the softkeys or in the display area when some menus are selected.
To make cursor measurements
1 Connect a signal to the oscilloscope and obtain a stable display.
2 Press the [Cursors] key. The key will illuminate, indicating that cursors
are “on”. (Press the key again when you want to turn cursors off.)
3 In the Cursors Menu, press Mode; the, select the desired mode:
• Manual — X, 1/X, and Y values are displayed. X is the
difference between the X1 and X2 cursors and Y is the difference
between the Y1 and Y2 cursors.
• Track Waveform — As you move a marker horizontally, the vertical
amplitude of the waveform is tracked and measured. At the bottom
of the display, 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.
If you intend to make cursor measurements on a trace that you recall from memory, be sure
to recall both setup and trace. See “To recall waveform trace and/or oscilloscope setup” on
page 216.
