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!
Butterworth (maximum flat amplitude response) or Bessel (maximum flat
group delay) response, to use other terms. The distinction is well known
in filter theory.
