Thank you for the information. I have since obtained a bench scope and Parallax USB Oscilloscope with Understanding Signals. I decided with the Parallax USB Oscilloscope solution simply because it has been around for some time and is compatible with the Understanding Signals book. I use the Parallax USB Scope and Understanding Signals manual as a benchmark to compare results with my bench scope. So far, I would highly recommend the Parallax USB Oscilloscope with Understanding Signals as a tool to become more familiar with a scope. I would have gone with the PropScope if a revised Understanding Signals book for PropScope was available. I'm confident that the PropScope is a high-quality product consistent with other Parallax products, and I expect to get my hands on one during the upcoming convention in June.
I'm glad you found the original "Understanding Signals" book to be useful to you!
I just wanted to let you know we are working on the book "Understanding Signals with the PropScope" right now. The first draft is written, and although it follows a similar outline as the original, it is pretty much a complete rewrite though I'm sure some of the BASIC Stamp programs will be familiar. It will be a much thicker book than the current "Understanding Signals" because the PropScope has a much larger set of functions and features. The book will be available printed, and also as a free PDF download.
