Tektronix, Type 465B) perform appropriate adjustment for model identified in table 10.
Rise time will be 3.5 ns or less.
NOTE
Make adjustments in order listed in table 10 below for
optimum flat-top square wave.
(11) Press VERT MODE CH 1 pushbutton to on (in).
(12) Repeat technique of (8) through (10) above for CH 1. If square wave displayed
exceeds tolerances listed in (10) above, perform appropriate adjustments for model
identified in table 10. Risetime will be 3.5 ns or less.
