This is the ‘ScopeCorder Introduction Workbook’ for the DL850E series ScopeCorders. This workbook is created to
help ScopeCorder users understand the basic principles of working with their instrument.
In a series of exercises we will walk through the most commonly used functionality, but also address some unique
ScopeCorder features.
To get familiar with the ScopeCorder’s knobs & keys and their functions, please consider starting with AppendixA.
In case you have questions, remarks or suggestions related to this document or the ScopeCorder instrument, please
contact your local representative, myself or go to the Additional resources for support.
Enjoy the exercises!

1. Factory reset
ScopeCorder introduction workbook
Copyright © Yokogawa Electric Corporation
A Factory RESET may be performed if the set-up status of the ScopeCorder is unknown.
It may be useful before performing these exercises, or before beginning a new test procedure.
Follow these steps:
1. Turn OFF the ScopeCorder
2. Hold the RESET button while turning ON the ScopeCorder
3. Continue to hold the RESET button
4. Wait for the confirmation message (you will hear a BEEP):
‘Turned on pressing the RESET key. Will initialize’
5. Release the RESET button
6. Press the ESC button
DONE! Factory reset has been completed.
Initialize vs. Factory Reset
A factory reset will initialize ALL
settings, including those of the
communication interfaces. To
maintain communication interface
settings, use SETUP » INITIALIZE.

2. A simple acquisition
ScopeCorder introduction workbook
Copyright © Yokogawa Electric Corporation
Prerequisite: You may wish to perform a factory reset (Exercise 1) before this exercise to ensure your
ScopeCorder matches the setup of the ScopeCorder used in these exercises.
In this exercise you will make a simple waveform acquisition. Please connect CH1 to the PROBE
COMP pins on the front of the ScopeCorder using a suitable 10:1 or 1:1 probe / test lead. Leave all
other channel inputs disconnected. Press CH1 and adjust PROBE to either 10:1 / 1:1 as appropriate
for the input lead-set being used.
Follow these keystrokes:
Active Channels
If other channels are still enabled, please
turn them OFF by double-pressing each one
of the corresponding channel buttons, such
as CH 2, etc.
PROBE COMP connection
DONE!

Show the signal over a longer time period
Use the Tim/DIV knob to change the length
of your acquisition.
Longer memory, higher sample rate
Increase the record length (memory size) to
increase the sample rate. To do so, press:
ACQUIRE » Use the Jog Shuttle to adjust the
Record Length.

3. Sample rate calculation
ScopeCorder introduction workbook
Copyright © Yokogawa Electric Corporation
Sample Rate= Main (Record Length)
Total Time
=10.000 points
200μs/DIV×10 DIV
=10.000
2000μs=10.000 0,002s
=5MS/s
What sample rate & measurement time
settings are possible?
Dependent on channel count, available
memory and other parameters different
sample rates & measurement times are
available. Review Appendix C for more
information.

Use the 2nd Zoom channel
In the given example, the second Zoom
channel has been activated to get even more
detail by zooming in on Zoom channel 1. To
do this press:
Zoom1/Zoom2 » Display (set to: On) » Zoom2
Source (set to: Zoom1)
Now use the Magnitude and Position knobs
to fine tune the Zoom windows.

Prerequisite: Perform Exercise 2 first, or acquire a waveform.
In this exercise you will save a waveform to a binary file.
Follow these keystrokes:
Enter a file name with the navigation keys
DONE!
One button operation
After you have performed the
above setup, you simply press one
button SAVE. You can skip all but
the last step, if you wish for the
DL850E(V) to name file(s) for you.

To see a directory listing with your
file, press: FILE » UTILITY and use
the SET button and SHUTTLE-knob
to set PATH=HDD, in this example.

Prerequisite: Perform Exercise 5 first, or use another saved waveform.
In this exercise you will load and view a binary file containing a waveform.
Follow these keystrokes:
DONE!
The signal acquired in Exercise 2
Will now be displayed on the screen. Note that the ‘PATH = HD-0’. Highlight the file created in the previous exercise.

Prerequisite: Perform Exercise 2 first, or acquire a waveform.
In this exercise you will save a screen image as JPEG, BMP or PNG file. Some steps may be abbreviated.
Follow these keystrokes:
DONE! Do you have to stop acquisition before saving?
Not for storing image files. It is required to stop acquisition for saving
waveform files (which is still enabled due to Exercise 5).
To only save image files: press SHIFT + SAVE » disable Waveform Save.
One key, two actions
As you just have experienced, the SAVE key can be used for saving a
waveform file, a screen image or a combination of both.
