ELECTRONIC PRINCIPLES - OD1647 - LESSON 1/TASK 3
(m) SLOPE Switch. An alternateaction switch that provides
for selecting a portion of the trigger signal to start the
delayed sweep. The (IN) position provides that the delayed
sweep is triggered from the positivegoing portion of the
trigger signal. The (OUT) position provides that the delayed
sweep is triggered from the negativegoing portion of the
trigger signal.
(n) COUPLING Switch. An alternateaction switch that
provides for the selection of the method of coupling the trigger
signal to the delayed trigger circuits. The ac (IN) position
provides that the dc components are rejected and ac signals
below approximately 30 Hertz are attenuated; signals between 30
Hertz and 50 megahertz are accepted intact. The dc (OUT)
position provides that all signals from the dc to 50 megahertz
are accepted intact.
(o) SOURCE Switch. An alternateaction switch that provides
for the selection of the source of the delayed trigger signal
determining the function of DLY'D TRIG IN connector. The INT
(IN) position provides that the delayed trigger signal is
obtained from the external source through the DLY'D TRIG IN
connector.
(p) DELAY TIME MULT 10Turn Dial Potentiometer. Provides
for selecting the variable sweep delay between 0 and 10.0 times
the delay indicated by the TIME/DIV or DLY TIME switch setting.
(q) MAIN TRIG IN OR AMP IN. Provides for the connection of
the connecting cable to the dual time base for external
triggering signal input. When the MAIN TRIGGERING AMPLIFIER
SOURCE EXT or EXT 10 switch is pressed and the TIME/DIV 0R
DELAYED TIME switch is set to any other position than AMPL, the
connector provides for external trigger input to the main
triggering circuits. When the MAIN TRIGGERING AMPLIFIER SOURCE
EXT or EXT 10 switch is pressed and the TIME/DIV OR DLY'D TIME
switch is set to AMPL, the connector provides for external
horizontal input.
(r) DLY'D/TRIG IN Connector. Provides the connection point
for connecting the cable to the dual time base for external
delayed triggering signal input.
