graticule divisions involved and multiplying by the scale factor. If you counted 6 major
vertical graticule divisions between the minimum and maximum values of a waveform
and knew you had a scale factor of 50mV/division, you could easily calculate your
peak-to-peak voltage as follows:
6 divisions x 50mV/division = 300mV.
2.10.2 Cursor measurement
Cursor: This method allows you to take measurements by moving the cursors. Cursors
always appear in pairs and the displayed readouts are just their measured values.
There are two kinds of cursors: Amplitude Cursor and Time Cursor. The amplitude
cursor appears as a horizontal broken line, measuring the vertical parameters. The
time cursor appears as a vertical broken line, measuring the horizontal parameters.
The cursor measurement includes two modes: Manual mode and Tracking mode.
1. Manual mode:
Horizontal cursors or vertical cursors appear in pair to measure time or voltage, and the
distance between the cursors can be manually regulated. The signal source should be
set as a waveform to be measured before the cursors are used.
2. Tracking mode:
A horizontal cursor is intersected with a vertical cursor to form a cross cursor. The cross
cursor is automatically located on the waveform, and the horizontal position of the
cross cursor on the waveform is regulated by selecting “Cur A” or “Cur B” and rotating
the [UNIVERSAL] knob. The coordinates of the cursor point will be displayed on the
screen of the oscilloscope.
Push the CURSOR button to display the Cursor Menu.
Select a measurement cursor and display it.
Select a waveform to take the cursor measurement.
Use the readouts to show the measurement.
A selected cursor is highlighted, which can be moved
freely. Both cursors can be selected and moved at the
same time. The box behind the cursor displays the
location of the cursor.
