The input of the settling time fixture is driven by a flat top pulse
generator. The error signal output from the false summing node
of A1 is clamped, amplified by A2, and then clamped again. The
error signal is thus clamped twice: once to prevent overloading
Amplifier A2 and then a second time to avoid overloading the
oscilloscope preamp. The Tektronix oscilloscope preamp type
7A26 was carefully chosen because it does not overload with
these input levels. Amplifier A2 needs to be a very high speed
FET-input op amp; it provides a gain of 10, amplifying the error
signal output of A1.
