AL T Signals
applied
appear on the screen alternatively at each sweep.
This setting is used when the sweep time is short in
2-channel observation.
CHOP
At this setting, the input signals applied respec
tively to CHI
250 kHz independent of the sweep and at the
same time appear on the screen. This setting is
used when the sweep time is long in 2-channel
observation.
ADD The algebraic sum of the input signals applied
respectively
to
screen ..
@
CH2 INV button
Used to inverse the polarity of the input signal applied
to
CH2.
Inversion occurs in a state where the knob
of the pushbutton is depressed
normal when the knob is in protruded state
This switch is conveniently used in the comparison of
two
waveforms having different
observation of the waveform of the difference signal

(3) Controls of horizontal deflection system
@
TIME/DIY �lect switch
Sweep time ranges are 18 steps from 0.5 psjdiv to 0.2s/
div.
X-Y This position is used when using the instrument as
an X- Y oscillsocope.
In this position, the
nected
signal is applied to the input of CH2 and has a
deflection range from less than one millivolt to
5 volts/div at a reduced band-width of200 kHz.
@
SWP VARiable control
Works as CAL and the sweep time is calibrated to the
value indicated by TIME/DIY.
TIM E/DIV of sweep can be varied continuously when
shaft is out of CAL position.
Then the control is rotated in the direction of arrow to
).
the full, the CAL state is produced and the sweep time
is
calibrated to the value indicated by TIME/DIY.
Counterclockwise rotation to the full delays the sweep
by 2.5 times or more.
