(@) AC-GND-DC
@ AC-GND-DC
Three-position lever switch which operates as follows:
AC:
Blocks
dc
component
of
channel
1 input
signal.
Opens signal path and grounds input to ver-
tical amplifier. This provides a zero-signal base
line, the position of which can be used as a
reference when performing dc measurements.
Direct input of ac and dc component of chan-
nel 1 input signal.
Three-position lever switch which operates as follows;
AC:
Blocks dc component of input signal.
GND:
Opens signal path and grounds input to vertical
amplifier. This provides a zero-signal base line,
the
position
of
which
can
be
used
as
a
reference when performing dc measurements.
Direct input of ac and dc component of input
signal.
INPUT Jack
Vertical input for channel 1 trace. Vertical input for X-Y
operation.
©) INPUT Jack
Vertical input and vertical input for X-Y operation.
VOLTS/DIV
Vertical attenuator for channel 2; provides step adjust-
ment of vertical sensitivity. When
VARIABLE
control
@) is set to CAL, vertical sensitivity is calibrated in 12
steps from 5 V/div to 1 mV/div.
In X-Y operation, this control provides step adjustment
of horizontal sensitivity.
VARIABLE Control
Rotation provides fine control of channel
2 vertical
sensitivity. In the fully clockwise (CAL) position, the
vertical attenuator is calibrated. In X-Y operation, this
control becomes the fine horizontal gain control.
AC-GND-DC
Three-position lever switch which operates as follows:
AC:
Blocks
dc
component
of
channel
2 input
signal.
Opens signal path and grounds input to ver-
tical amplifier. This provides a zero-signal base
line, the position of which can be used as a
reference when performing dc measurements.
Direct input of ac and dc component of chan-
nel 2 input signal.
INPUT Jack
Vertical input for channel
2 trace in normal sweep
operation. External horizontal input in X-Y operation.
CH2 INV
Inthe NORM position (button released), the channel 2
signal is non-inverted.
In the INV
position
(button
engaged), the channel 2 signal is inverted.
4 POSITION, X-Y <>
Rotation adjusts vertical position of channel 2 trace.
In X-Y operation adjusts horizontal position of display.
