CONTROLS AND INDICATORS
GENERAL FUNCTION CONTROLS
1.
ON Indicator. Lights when oscilloscope is “on”.
2.
POWER Pushbutton. Turns oscilloscope “on” and
“off”.
3.
INTENSITY Control. Adjusts brightness of trace.
4.
TRACE ROTATION Control. Adjusts to maintain
trace at a horizontal position.
5.
FOCUS Control. Adjusts trace focus.
6.
GND
Terminal. Oscilloscope chassis ground
jack, and earth ground via three-wire ac power cord.
7.
CAL Terminal. Terminal provides 0.5 V p-p, 1 kHz
(nominal) square wave signal. This signal is useful for
checking probe compensation adjustment, as well as
providing a rough check of vertical calibration.
VERTICAL CONTROLS
8.
VERTical MODE Switch. Selects vertical display
mode. Four-position lever switch with the following
positions:
CH1:
Displays the channel 1 signal by itself.
CH2/X-Y:
CH2: displays the channel 2 signal by itself.
X-Y: used in conjunction with the X-Y control and
Trigger SOURCE switch to enable X-Y display
mode.
DUAL:
Displays the channel 1 and channel 2 signals simul-
taneously. Dual-trace mode may be either alternate
or chopped sweep; see the description under CHan-
nel 1 POSition/PULL CHOP control.
ADD:
The inputs from channel 1 and channel 2 are
summed and displayed as a single signal. If the
Channel 2
POSition/PULL INVert control is
pulled out, the input from channel 2 is subtracted
from channel 1 and the difference is displayed as a
single signal.
9. CH1 AC-GND-DC Switch. Three-position lever
switch with the following positions:
AC:
Channel 1 input signal is capacitively coupled; dc
component is blocked.
GND:
Opens signal path and grounds input to vertical
amplifier. This provides a zero-volt base line, the
position of which can be used as a reference when
performing dc measurements.
