CH2 INPUT Jack
Vertical input for channel 2 trace in normal sweep oper-
ation. X-axis input in X-Y operation.
MODE Switch
Selects the basic operating modes of the oscilloscope.
CH1:
Only the input signal to channel 1 is displayed
as a single trace.
CH2:
Only the input signal to channel! 2 is displayed
as a single trace.
ALT:
Alternate sweep is selected regardless of sweep
time.
CHOP: Chop sweep is selected regardless of sweep
time at approximately 300 kHz.
The waveforms from channel 1 and channel 2
inputs are added and the sum is displayed as a
single trace. When the CH2 INV © button is en-
gaged, the waveform from channel 2 is sub-
tracted from the channel 1 waveform and the
difference is displayed as a single trace.
ADD:
GND terminal/binding post.
Earth and chassis ground.
CAL Terminal
Provides 1 kHz, 1 V peak-to-peak square wave signal.
This is useful for probe compensation adjustment.
EXT TRIG INPUT Jack
Input terminal for external sync signal.
When SOURCE switch is selected in EXT position, the
input signal at the EXT TRIG INPUT jack becomes the
trigger.

POWER Switch
A press of this switch turns the power ON.
POWER Indicator
Lights when the POWER switch is pressed.
INTEN (REAL) Control
Controller
for adjusting
brightness
of the real-time
waveform.
INTEN (READOUT) Control (CS-5130 only)
Controller for adjusting brightness of the READOUT
value.
*
By turning the controller clockwise
up to the very
end, the READOUT value becomes brightest; turn-
ing counterclockwise turns readout function OFF and
makes the value disappear.
FOCUS/PULL ASTIG Control
FOCUS:
Focus adjustment
ASTIG:
Used to bring the waveform into the best
condition with the FOCUS adjustment by ad-
justing trace and spot aberration. Pull the
knob to make a spot circular.
