TV-H:
Used for triggering from television horizontal sync
pulses. Also serves as hi-pass (low frequency reject)
trigger coupling.
LINE:
Signal derived from input line voltage (50/60 Hz)
becomes trigger.
29.
TRIGger LEVEL/PULL (–) SLOPE Control.
TRIGger LEVEL:
Trigger level adjustment; determines the point on
the triggering waveform where the sweep is trig-
gered. Rotation in the (–) direction (counterclock-
wise) selects more negative triggering point;
rotation in the (+) direction (clockwise) selects
more positive triggering point.
PULL (—) SLOPE:
Two-position push-pull switch. The “in” position
selects a positive-going slope and the “out” position
selects a negative-going slope as triggering point for
main sweep.
30.
EXTernal TRIGger Jack. External trigger input for
single- and dual-trace operation.

31.
Fuse Holder/Line Voltage Selector. Contains fuse
and selects line voltage.
32.
Power Cord Receptacle.
33.
CH 2 (Y) SIGNAL OUTPUT Jack. Output terminal
where sample of channel 2 signal is available. Ampli-
tude of output is nominally 50 mV per division of
vertical deflection seen on CRT when terminated into
50
Ω
. Output impedance is 50
Ω
.
34.
Z-Axis Input Jack. Input jack for intensity modula-
tion of CRT electron beam. TTL compatible (5 V p-p
sensitivity). Positive levels increase intensity.
35.
Handle/Tilt Stand.
36.
Feet/Cord Wrap.
