=== 545B Vertical Path ===
The Type 545B differs significantly from the 545 and 545A.   
The Type 545B differs significantly from the 545 and 545A.
It was designed by [[Dave Barton]].   
It has a partly solid-state, non-distributed vertical amp, and uses the [[154-0478-00]] CRT which is also used in the [[544]], [[546]], and [[547]].  Improvements in CRT design, including reduced deflection plate capacitance and increased sensitivity increased the vertical scale in the 545B from 4 to 6 divisions.  The improved CRT also uses a ceramic envelope, with flat glass faceplate that has internal graticule markings, eliminating parallax errors.
