﻿These are the installation instructions for replacing the firmware
in a DPO2000 or MSO2000 series oscilloscope with the firmware in
the DPO2000_v*.zip file. Note that even though the file is named "DPO2000",
it supports the MSO2000 series products as well.

Contents of this zip package:

    install_v1.06.txt  - this text file
    DPOMSO2000ExternalReleaseNotes_v1.06.txt 
                                - describes differences between firmware versions
    firmware.img       - oscilloscope firmware file readable by the
                       DPO2000 and MSO2000

Caution:
 
    Loading new firmware will cause all previously saved setups and reference 
    waveforms to be deleted. You may wish to save the internal setups to
    external .set files, and the internal reference waveforms to external 
    .isf files, before loading the new firmware.
 
    (To find the relevant menus referred to in the following directions,
    push the Save/Recall button labeled "Menu" which is located on the
    oscilloscope front panel, below the screen.)
 
    To save an internal saved setup to a .set file, first recall the setup.
    Then go to the Save Setup menu and select "To File" and proceed to save
    to a USB flash drive. After the new firmware has been loaded, you may
    recall each .set file. Save each one in turn to an internal saved
    setup by using the Recall Setup and Save Setup menus respectively.

    To save an internal reference (Ref) waveform to a .isf file, first
    display (turn on) the reference waveform. Then go to the Save Waveform
    menu, set the Source to the appropriate Ref, set the Destination to
    File, and proceed to save to a USB flash drive. The oscilloscope
    can only recall single-waveform .isf files.  You should:
      - Make sure to use Internal (.isf) file format, not Spreadsheet
        (.csv). Push the File Details side bezel button to adjust the file
        format if necessary.
      - Be certain to save each reference waveform to a separate .isf file.
        Do not use the save-all-waveforms-to-a-single-file feature.
    After the new firmware has been loaded, you can recall each .isf file to
    one of the reference waveforms, using the Recall Waveform menu.

Instructions:

    1.  Unzip the DPO2000_v*.zip file and place the 'firmware.img' 
        file on a USB flash drive in the root or topmost folder.

    2.  Turn the oscilloscope off.

    3.  Insert the USB flash drive into the USB Host port on the front
        of the oscilloscope.

    4.  Turn on the oscilloscope.

        After a few seconds, the screen will display a message stating
        that the firmware upgrade procedure is in progress.

        Do not turn off the oscilloscope or remove the USB flash drive
        until notified to do so! The procedure takes between eight and
        twelve minutes, depending on the brand and speed of USB flash
        drive being used.

    5.  After the screen states the upgrade is complete, turn off the
        oscilloscope.

    6.  Remove the USB flash drive.

    7.  Turn on the oscilloscope.

        When the oscilloscope powers up, you should see a message indicating
        that the firmware upgrade procedure has successfully completed.

Currently Installed Version:

    The firmware version currently installed in the oscilloscope is shown
    in the About menu. Push the Utility button, then the bottom bezel
    button labeled "About".

Troubleshooting:

    - If you try to load an older version of firmware, or the same version
      that is currently installed, the oscilloscope will not load the
      firmware and will display a message indicating the firmware on the
      USB flash drive is not newer than the current firmware.

      You can force the oscilloscope to load the USB flash drive's
      firmware.img file by creating an empty file called "override.txt"
      on the USB flash drive in the root or topmost folder.

    - If the firmware does not load, verify that the USB flash drive is
      supported by the oscilloscope. Push the Save/Recall Menu button and
      attempt to save a setup to the USB flash drive. If you cannot save
      and recall .set files, the USB flash drive may not be supported.
      Try another brand of USB flash drive. 

    - If the firmware does not load and the USB flash drive otherwise works
      fine, then the firmware.img file may be corrupted. Try downloading
      the firmware again.

    - If you are still unable to load the new firmware, please contact the
      Tektronix Technical Support Center. Customers calling within the U.S.
      call 1-800-833-9200 press 3. Customers calling from outside the U.S.
      call 503-627-2400.
