Comparison
of
single sweep and repetitive sweep presentation of a
damped
sine
wave. In
the reptitive sweep presentation, it
is difficult to deter
mine
what
is
being
presented. However, in the single
sweep presentation the
damped
sine wave
can be clearly seen.
Sweep
Magnifier
The
sweep
magnifier allows you to
expand any two-
centimeter
portion of
the displayed waveform to
the full
ten-centimeter
width
of the graticule. This is done by first
using
the
HORIZONTAL POSITION control to move the
portion
of the display you wish to expand to the center of
the graticule, then placing
the 5X MAGNIFIER switch in the
ON
position. When
the 5X MAGNIFIER switch is
at ON,
the
5X
MAGNIFIER lamp lights
to indicate the magnifier is
on.
Any portion of the original unmagnified display can
then
be
observed by rotating the HORIZONTAL POSITION
controls.
The
sweep magnifier can be used with either time
base
unit.
In
magnified
sweep operation, the sweep rate indicated
by
the position
of the
TIME/CM control is divided by 5 to
obtain
the
actual time required for the spot to
move one
centimeter. For
example,
if
the TIME/CM
control is set at
5
MILLISEC,
the actual time per centimeter is 5 milliseconds
divided
by 5, or 1 millisecond per
centimeter. The actual
time
per
centimeter must be used for all measurements of
time.

Amplitude
Calibrator
The
amplitude
calibrator provides a convenient source
of
square waves
of known amplitude at a frequency of
approximately
1 kc. The square-waves
are used primarily
to
adjust probes
and to verify
the calibration of the vertical
deflection
system
of
the oscilloscope and plug-in
unit.
Calibrator
square-waves are adjustable
from 0.2 milli
volt,
peak-to-peak,
to 100 volts, peak-to-peak, in 18 steps.
The
amplitude is controlled
by the setting of
the
AMPLITUDE
CALIBRATOR
switch and
is
accurate within 3%
of the AM
PLITUDE CALIBRATOR
switch setting when the
output is
connected
to a high impedance load.
Dual-Trace
Displays
The
Type CA Plug-In Unit allows you to obtain two
separate traces
on the face of the crt. This permits you to
display two
functions simultaneously. Detailed instructions
for
operating the Type
CA Unit in conjunction with the
Type
535A Oscilloscope are contained
in
the Instruction
Manual
for the Type CA Unit.
