Operating instructions
This
option
provides
a
means
to
obtain
an
X-Y
display
.
The
horizontal
and
vertical
(X-Y)
signals
are
applied
to
the
inputs of
a
dual-trace
amplifier
unit,
or
two
single
amplifier
units
.
The
horizontal
signal
is
then
routed
through
the
amplifier
and main-
frame
trigger
paths
to
the
Option 2
instrument
.
The
front-panel
DISPLAY
MODE
switch
selects
either
normal
sweep
displays
or
X-Y
displays
.
A
functional

of
the
