the 535a is a fine choice as a general purpose lab scope
if 15 mhz will do it.
im a bit down on the 545a because of its 4 cm verticle height + very complex vert delay line
as a plug in tester i think that it will test any letter and number plug ins if 15 mhz will do you

Christian,
BAMA has the 585 manual. A 581 is like a 585 but has only one timebase.
The vertical amps will be the same, and the power supplies will be very
close.
The one sweep on the 581 will be the same as "A" sweep on the 585.
Right: To use letter series plug-ins with a 581 you need an adapter
plug-in, type 81.
The plug-in of choice for the 581 is the type 82, a dual channel.
Single channel is type 86.
Both 581 and 585 came in "A" versions.
Good luck!
