Let me start over. In another thread, I asked what equipment that I might need to accomplish measurement of filters that I work with. After buying the recommended equipment (or at least some of it), I found that it would require graphing out responses on paper. While I wouldn't mind doing this, I can promise that it is an opportunity for me to make even more errors than I usually do. I almost bought a third piece of equipment, i.e. a sweep frequency generator, but then stopped short until I get a better idea of the right equipment needed. First of all, I have purchased an Oscilliscope, and a benchtop DMM capable of signal generating. That's fine. These are great pieces that I have ended up with, and will keep, but I need to complete the set in order to measure the effect of these notch filters that I work on (among other filters). Soooo, what is the recipe? Thanks in advance.
