1st Edition
Displaying the Waveform
Here, use the instrument’s probe compensation signal (frequency: approx. 1 kHz, amplitude: approx. 1 V,
square wave signal) for the input signal.
1.
Press AUTO to execute auto setup.
1
Voltage scale: 500 mV/div
When you execute auto setup, the voltage scale (V/div), time scale (Time/div), trigger level, and the like
are automatically set to values suitable for the input signal.*
* The auto setup feature may not work properly for signals that include a DC component or high-
frequency components.
To measure the voltage with high accuracy, adjust the vertical scale so that the input signal is
measured with the largest possible amplitude.
Changing the Vertical Axis Settings
Change the vertical scale (voltage sensitivity) from 500 mV/div to 200 mV/div to increase the waveform
amplitude. Setting the voltage sensitivity means setting the voltage per grid division (V/div).
1.
Press CH (
1
).
2.
Use the SCALE knob to change the voltage sensitivity to 200 mV/div.
Voltage sensitivity: 200 mV/div
The waveform is expanded vertically
causing a portion of the waveform to
go off the screen.

Measurements may not be performed correctly in this condition. Lower the vertical position to that the
entire waveform can be seen.
3.
Use the POSITION knob to move the vertical position down by 2 divisions.

Guide (IM DLM5058-01EN).

Changing the Trigger Position from 50% (screen center) to 30%
When you start waveform acquisition, the instrument triggers according to the specified conditions
and displays the waveform captured in the acquisition memory. You can move the trigger position
on the screen to change the display ratio of the data previous to the trigger point (pre-trigger
section) and the data after the trigger position (post-trigger section).
1.
Use the POSITION to move the trigger position to the left by 2 divisions. The trigger position is
set to 30%.
Set the trigger position ( ) to 30%.
Post-trigger section
The waveform moves to the left causing more of the
waveform after the trigger (post-trigger section) to
be seen.
Pre-trigger
section

For details on triggers, see chapter 4, “Trigger,” in the Features Guide (IM DLM5058-01EN).
Measuring the Waveform
Use vertical cursors (ΔT cursors) to measure the time and voltage of the displayed waveform.
1.
Press CURSOR.

Measured values
2.
Press the Type soft key to select (ΔT cursor).
Two vertical cursors, the times (T1, T2) and voltages (V1, V2) at the cursor positions, and other
measurements are displayed.
3.
Turn the jog shuttle ( ) to move a cursor.
The cursor that the jog shuttle controls switches each time you press SET ( ). You can also
select both T cursor 1 and T cursor 2.
Saving the Waveform Screen Image
You can save screen captures. The available data formats are PNG, BMP, and JPEG.

Press the Print To soft key to set the output destination to File.
3.
Use the Format soft key to set or view the data format, the File List soft key to set or view the
save destination, and the File Name soft key to set or view the file name.
4.
Press PRINT. A screen capture is saved.
• For details on saving screen captures, see chapter 16.5, “Saving Screen Captures to Files,” in
the User’s Manual (IM DLM5058-02EN).
• To use the built-in printer (option), change Print To to BuiltIn.
Changing the Horizontal Axis Settings
Change the horizontal (time) scale from 200 µs/div to 100 µs/div. Setting the time scale means setting
the time per grid division.
1.
Use the TIME/DIV knob to change Time/div to 100 µs/div.
Time/div: 200 µs/div
10 div = 2 ms
Time/div: 100 µs/div
10 div = 1 ms
(the waveform is expanded horizontally)

For details on the horizontal axis, see chapter 3, “Horizontal Axis (Time Axis),” in the Features
Guide (IM DLM5058-01EN).
Changing the Edge Trigger Settings
Edge triggers are simple triggers that are activated when the trigger source passes through a trigger
level. A change in the waveform that causes it to pass through a trigger level is called an edge.
When you execute auto setup, the edge trigger is automatically set.

Here, change trigger slope and trigger position settings of the edge trigger.
Changing the Trigger Slope from Rising to Falling
Use the slope to set the direction of the edge. There are two edge directions: rising (movement from
a low level to a high level) and falling (movement from a high level to a low level). Setting the slope
allows triggers to be activated on the rising edge ( ), falling edge ( ), or both ( ).

Press EDGE.

Press the Slope soft key to select (falling). The instrument will trigger on the falling edges of
the trigger source.
