Wilkie – thanks for the +1 and clarification. And I appreciate the schematic you shared for the sig-gen. I’d like to find a similar circuit the both displays and controls the frequency and amplitude. Based on the schematic you shared, looks like ‘circuitstoday.com’ is a good place to start. I know I could throw money at manufactured sig-gen, but those funds are scarce for me and I have parts and enclosures and am sure I can locate some inexpensive meters. Thanks again Wilkie.
