5 Making Measurements
You can measure waveform data using cursors. Cursors are
horizontal and vertical markers that indicate X-axis values
(usually time) and Y-axis values (usually voltage) on a selected
waveform source. The position of the cursors can be moved by
turning the Entry knob. When you press the Cursors key, it will
illuminate and the cursors will turn on. To turn cursors off,
press this key again until it is not illuminated, or press the Quick
Meas key.
Cursors are not always limited to the visible display. If you set a
cursor, then pan and zoom the waveform until the cursor is off
screen, its value will not be changed, and if you pan the
waveform back again it will have the cursor in the original
place.
To make cursor measurements
A brief description of how to make cursor measurements is
given on page 95.
The following steps guide you through using the front-panel
Cursors key. You can use the cursors to make custom voltage or
time measurements on the signal.
1Connect a signal to the oscilloscope and obtain a stable
display.
2Press the Cursors key, then press the Mode softkey.
X and Y cursor information is displayed on the softkeys. ∆X,
1/∆X, ∆Y, and binary and hexadecimal values are displayed
on the line above the softkeys. The three cursors modes are:
•Normal — ∆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.
