I ordered a used copy for $25. I'm looking at running about 1KHz. The test circuit says 25 Hz to 20 KHz. Not sure about the duty cycle or amplitude. I picked 1 KHz out of my butt so I'm open to suggestion. My total lack of electronics knowledge makes it easy for me to believe it will be easy to do this. Maybe after I get my copy of, "The Art of Electronics" I'll realize how hard it really is.
