Overwriting the user password
Use this procedure to change the user password. The user password is not currently functional or accessible in the
oscilloscope user interface, but it is accessible from the programmatic interface. The user password is used to protect a
"user string" that can be set and displayed in the UI. This functionality is a legacy functionality and while the user password
does exist through the programmatic interface, there is no function to display the user string in the user interface on this
instrument.
1. Connect a PC to the oscilloscope (Ethernet or USB Device port).
2. Use a Windows remote terminal or similar program to communicate with the oscilloscope. Tap the Utility > I/O menu on
the oscilloscope to see the current instrument settings.
3. Send the following commands to the oscilloscope:
a. :PASSWORD "XYZZY"
(or current password if changed from the default of "XYZZY")
b. :NEWPASS "NEWPASSWORD"
(Or other password up to 16 characters)
If you do not have access to a program that supports sending programmatic commands to the instrument, do the following:
1. Copy the preceding commands to a text file.
2. Compress the text file into a ZIP archive file that ends in ".set".
3. Copy the file to a USB drive.
4. Insert the USB drive into the oscilloscope.
5. Recall the file from the Recall Setup dialog box (File > Recall > Setup tab).
For more information on using programmatic commands, refer to your product programmer manual, available at
www.tek.com/manuals.
