Measuring with Cursors
Cursors are important tools that aid you in measuring signal values. Cursors are markers (lines or cross-
hairs) that you can move around the grid or the waveform itself. Use cursors to make fast, accurate
measurements and to eliminate guesswork. There are three basic types:
• Voltage (Vertical) cursors are dashed lines that you move vertically on the grid to measure the voltage
levels of a signal. When used on a FFT waveform dBV values are measured.
• Time (Horizontal) cursors are dashed lines that you move horizontally on the grid to measure the time
values of a signal. When used on a FFT waveform frequency values are measured.
• Track (Horizontal) cursors are cross-hairs that you move horizontally along any channel waveform.
Place them at a desired locations along the time axis
to read the signal’s voltage levels at the selected
times.
Step 1:
Reset the scope configuration to the default factory settings using the front panel DEFAULT
SETUP button. An alternative method is to use the front panel SAVE/RECALL button, then press the
Type button until Factory is displayed and finally press the Load button.
At any time the menu on the right-hand side of the screen can be removed/restored by pressing the front
panel MENU ON/OFF button.
Step 2:
Turn CH1 off and CH2 on by pressing the front panel CH1 and CH2 buttons. Pressing a
channel button also displays the corresponding vertical settings. DC coupling on CH2 is selected by
default. Check the slider switch on the probe is set to X10 and using the Probe button set 10X on the
screen.
