The difference between the 545A and 545 is the control ergonomics, not any major circuit design changes. | |||
The difference between the 545A and 545 is the control ergonomics, not any major circuit design changes. | |||
The main improvement was to replace a pair of switches for the time base (8-position Time/Div and 6-position multiplier) | |||
The 545A uses the [[T5430]] CRT. | with a single 24-position switch, freeing up front panel space for a Time Base B Trigger Mode rotary switch. | ||
Additionally, the delaying timebase on the 545A supports delays up to 10 seconds while the 545 supports delays only up to 100 milliseconds. | |||
The older 545 uses the [[T54|T54 / 5BHP2]] CRT, P2 [[phosphor]] was standard. | |||
The 545A uses the [[T5430]] CRT for which also P2 phosphor was standard. | |||
The newer 545B came with the further improved [[T5470]] CRT (also used in the [[543B]], [[544]], [[546]] and [[547]]) and P31 phosphor as standard. | |||

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. | 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]].
