Voltage Measurement Cursors
6556
Voltage cursors can be used to measure signals displayed on CH 1 or CH 2.
Voltage measurements using cursors may be done on the CH 3, the CH 4 ,
or the ADD waveform by setting the VOL TS/DIV switch setting of th
selected measurement channel to the same scale factor as the signal to b
measured. However, the measurement accuracy on the CH 3 or CH 4 Input
signals will be less accurate than on the CH 1 or CH 2 Input signals . Volt
cursors are also available for making measurements In both the A Hori
zontal MODE and the X-Y Horizontal MODE.
Voltage Difference
Use the following procedure steps as a guideline In making voltage dif-
ference measurements using the positionable cursors.
1 . Apply the signal to the Input connector ( s) .

NOTE
For triggering to be set up properly when the AUTO SETUP
button Is pressed, connect the trigger-source signal to the
lowest numbered channel that will be turned on.
2 . Set:
VERTICAL MODE
Horizontal MODE
3. Press AUTO SETUP button.

4. Press the CURSOR VOL TS button to display the measurement selection
menu and select the I+- VOL TS

I cursors. The voltage cursors are
initialized to the peak-to-peak levels of the ·1owest numbered displayed
channel of either CH 1 or CH 2 ( see Figure 5-3) .
