TV-V position is used for observing a composite video signal at the frame rate.
TV-H position is used for observing a composite video signal at the line rate.
(18) Trigger SOURCE switch
To conveniently select the trigger source.
VERT: In case of vertical mode switch is CH 1 which automatically becomes registry source.
In case of vertical mode switch is CH 2 which automatically becomes registry source.
Note:
Measurement of VERT condition will be possible only Time/Div. switch is on 0,5 ms/Div. to 0.2
µs/Div. when it is dual mode. When there is no sign on CH 1 & CH 2 place the vertical mode switch
to dual and set TRIGGER SOURCE switch at VERT sweep may flickers but please be careful as it is
not out of order.
CH 1: When there is sign on CH 1 you may select trigger source CH 1.
LINE position selects a trigger derived from the AC power line. This permits the scope to stabilize
display linearelated components of a signal even they are very small compared to other components
of the signal.
EXT position selects the signal applied to the EXT TRIG IN connector.
(9) Trigger LEVEL control
To select the trigger-signal amplitude at which triggering occurs. When rotated clockwise, the trigger
point moves toward the positive peak of the trigger signal. When its control is rotated counter-
clockwise, the trigger point moves toward the negative peak of the trigger signal.
(8) Trigger SLOPE switch
To select the positive or negative slope of the trigger signal for initiating sweep.
(19) EXT TRIG IN connector
For applying external trigger signal to the trigger circuits.
Caution:
To avoid damage to the oscilloscope, do not apply more than 250 V (DC + Peak AC) between "EXT
TRIG IN" terminal and ground.
2.1.4 Miscellaneous Features
(31) EXT BLANKING INPUT connector
For applying signal to intersity modulate the CRT. Trace brightness is reduced with a positive signal,
and increased with a negative signal.
(17) PROBE ADJUST
Provides a fast-rise square wave of precise amplitude for probe adjustment and vertical amplifier
calibration.
(28) Ground connector
Provides an attachment point for separate ground lead.
2.1.5 Component Test Block (only PeakTech 2030 KT)
(35) Component Test switch
Push to test the component. Then the horizontal bar graph of 8 div is displayed on the screen.
(36) Component Test Input (red)
Be used for connecting component to component test circuit with DMM probe (red).
(37) Component Test GND (black)
Be used for grounding component to component test circuit with DMM probe (black)
