Fig. 2. Rear Panel Controls and Indicators.
DC:
Direct coupling of channel 1 input signal; both ac
and dc components of signal produce vertical de-
flection.
10.
CH1 (X) Input Jack.
Vertical input for channel 1.
X-axis input for X-Y operation.
11.
CH1 (X) VOLTS/DIV Control.
Vertical
attenuator for channel 1. Provides step adjustment of
vertical sensitivity. When channel 1
VARiable
control is set to
CAL,
vertical sensitivity is
calibrated in 10 steps from 5 mV/div to 5 V/div in a
1-2-5 sequence. When the X-Y mode of operation is
selected, this control provides step adjustment of
X-axis sensitivity.
12.
CH1 VARiable/PULL X5 MAG Control:
VARiable:
Rotation provides vernier adjustment of channel 1
vertical sensitivity. In the fully-clockwise
(CAL)
position, the vertical attenuator is calibrated. Coun-
terclockwise rotation decreases gain sensitivity.
In X-Y operation, this control becomes the
vernier X-axis sensitivity control.
PULL X5 MAG:
When pulled out, increases vertical sensitivity by a
factor of five. Effectively provides two extra sensi-
tivity settings: 2 mV/div and 1 mV/div. In X-Y
mode, increases X-sensitivity by a factor of five.
13.
CH1 POSition/PULL CHOP Control:
POSition:
Adjusts vertical position of channel 1 trace.
PULL CHOP:
When this switch is pulled out in the dual-trace mode, the
channel 1 and channel 2 sweeps are chopped and displayed
simultaneously (normally used at slower sweep speeds).
When it is pushed in, the two sweeps are alternately displayed,
one after the other (normally used at higher sweep speeds).
14.
CH2 POSition/PULL INVert Control:
POSition:
Adjusts vertical position of channel 2 trace. In X-Y operation,
rotation adjusts vertical position of X-Y display.
PULL INVert:
When pushed in, the polarity of the channel 2 signal is normal.
When pulled out, the polarity of the channel 2 signal is
reversed, thus inverting the waveform.
15.
CH2 VOLTS/DIV Control.
Vertical attenuator for channel 2.
Provides step adjustment of vertical sensitivity. When channel
2
VARiable
control is set to
CAL,
vertical sensitivity is
calibrated in 10 steps from 5 mV/div to 5 V/div in a 1-2-5
sequence. When the X-Y mode of operation is selected, this
control provides step adjustment of Y-axis sensitivity.
16.
CH2 VARiable/PULL X5 MAG Control:
VARiable:
Rotation provides vernier adjustment of channel 2 vertical
sensitivity. In the fully-clockwise
(CAL)
position, the
vertical attenuator is calibrated. Counterclockwise rotation
decreases gain sensitivity. In X-Y operation, this control
becomes the vernier Y-axis sensitivity control.
