CONTROLS AND INDICATORS
F R O N T P A N E L
(D
• POSITION/PULL CHOP
• POSITION: Rotation adjusts vertical position of
channel 1 trace.
In X - Y operation, rotation adjusts ver-
tical position of display.
CHOP: A L T / C H O P selector switch; pulling this switch
causes chop operation.
A L T operation: Alternate s w e e p is selected
regardless of sweep time as dual
trace
(CH1
and CH2) or triple
trace ( C H 1 , C H 2 and CH3).
CHOP operation: Chop sweep is selected regard-
less of sweep time at approx-
imately 2 5 0 kHz as dual trace
(CH1 and CH2) or triple trace
( C H 1 , CH2 and CH3).
(2) VOLTS/DIV
Vertical attenuator for channel 1 ; provides step adjustment
of vertical sensitivity. When VARIABLE control 3 is set to
C A L , vertical sensitivity is calibrated in 12 steps from
5 V/div to 1 mV/div.
For X-Y operation, this control provides step adjustment of
vertical sensitivity.
( D
VARIABLE Control
Rotation provides fine control of channel 1 vertical sen-
sitivity. In the fully clockwise (CAL) position, the vertical
attenuator is calibrated. For X-Y operation, this control
serves as the Y axis attenuation fine adjustment.
(4) AC-GND-DC
Three-position lever switch which operates as follows:
A C : Blocks dc component of channel 1 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.
DC: Direct input of ac and dc component of channel 1
input signal.
(5) INPUT Jack
Vertical input for channel
1
trace. Vertical input for X-Y
operation.
(6) VOLTS/DIV
Vertical attenuator for channel 2; provides step adjustment
of vertical sensitivity. When VARIABLE control 7 is set to
C A L , 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.
(7) VARIABLE Control
Rotation provides fine control of channel 2 vertical sen-
sitivity. In the fully clockwise (CAL) position, the vertical
attenuator is calibrated. In X - Y operation, this control
becomes the fine horizontal gain control.
(J)
AC-GND-DC
Three-position lever switch which operates as follows:
A C : Blocks dc component of channel 2 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.
DC: Direct input of ac and dc component of channel 2
input signal.
