I do. Very well, in fact. Unless you have swept a scope with a very well leveled sine generator, you are only guessing it is flat.
That's WHY Tektronix sells BOTH fast rise Pulse Generators and Leveled Sine Generators. In fact, on the Tek 7704 or 7704A (I forget which) there were "No Cost" options of maximally flat frequency response OR best pulse response. OR! -John ================ > At 07:00 PM 12/1/2009, J.
