Measuring Waveforms
This section explains the operation for measuring the voltage and period of the displayed waveform using the vertical cursors (V
cursors). Automated measurement of waveform parameters, computation, and other functions are also available for measuring pulse and
other waveforms.
Measure the Voltage Using the Vertical Cursors (V Cursors)
Section 11.5, “Measuring Waveforms Using Cursors” in the User’s Manual Part 2
The voltage (Y-axis value) and time (X-axis value) at the cursor position are displayed at the lower section of the waveform display area.

Press the
CURSOR
key.
3
Set the
jog shuttle
control to
Cursor1
.
4
Turn the
jog shuttle
to move
Cursor1
.
5
Likewise, move Cursor2.
If you set the jog shuttle control to both Cursor1
and Cursor2, the two cursors can be moved
simultaneously.

Note
Cursor Types
When X-Y waveforms are not displayed
•
Horizontal cursor (H cursor):
Measures the Y-axis value at the cursor.
•
Vertical cursor (V cursor):
Measures the X-axis and Y-axis values at the cursor.
•
Marker cursor:
The cursor moves on the waveform data and measures the data.
M1 (marker 1) to M4 (marker 4) can be specified on separate waveforms.
•
Angle cursor:
Set the measurement zero point (position of reference cursor Ref1) and the end point
(position of the reference cursor Ref2) on the X-axis and assign an angle corresponding
to the width of Ref1 and Ref2. Using this angle as a reference, this function measures
the angle of the two angle cursors (Cursor1 and Cursor2).
When X-Y waveforms are displayed
•
Horizontal cursor (H cursor):
Measures the Y-axis value at the cursor.
•
Vertical cursor (V cursor):
Measures the X-axis value at the cursor.
•
H&V Cursors:
Measures the X-axis and Y-axis values at the cursor.
•
Marker cursor:
The cursor moves on the waveform data and measures the data.
