How to read 8-bit digital signal through an Agilent DSO?
The manual for that scope is 2 gigabytes, so I'm not about to download it.  That being said...

Most scopes, including a different Agilent scope, have a variety of ways to save the waveform to a USB thumb drive.  Most of the time you'd save the waveform as a BMP or JPG file, although saving raw data as a text file or CSV file is common too.  Play around with those settings to see if there is one that you'd like.
