General
The Tektronix Type
533/533A
Oscilloscopes
are
general
purpose instruments well suited
to
laboratory use. Plug-in
preamplifiers
are
used
in
the
vedical-deflection
system,
permitting the instruments to be used
in
many specialized
applications, including, among others, wide
band,
dual
trace, low level, differential, maximum frequency response
and risetime,
and
transistor risetime checking. Specifica-
tions listed
below
apply
to
both
the
Type
533
and
Type
533A,
except
in
cases
that
are
otherwise noted.
Vertical Deflection System
All specifications for the Vertical Deflection System
of
the Type
533
and
533A Oscilloscopes
depend
upon the
plug-in unit used with
the
instrument. The following speci-
fications
are
given
assuming
that
a
Type
K plug-in unit
is
used.
Bandpass -
DC
to 15 me
(down
3

dB
at
15 me).
