Display is moved toward right when the knob is rotated
clockwise and toward left with counterclockwise rotation.
Sweep is magnified 10 times by pulling out knob of
POSITION.
In
this case the sweep time is 1 / 1 0 of the
value indicated by TIME/DIV. Bring the position of the
waveform desired to be magnified observed to the center
of the scale by operating
�
POSITION of the horizon­
tal axis. Next, switch
x
10 MAG switch to PULL (pulled
out state). Then the waveform placed at the center is
magnified in right and left directions. The sweep time

Magnified waveform
in this case is 1 0 times the sweep speed obtained by
TIME/DIV, in other words, the reading is l / I O of the
sweep time indicated.

SOURCE select switch (INT-LINE-EXT)
This switch is used to select the triggering signal source.
INT The input signal applied to CH I or CH2 becomes
the triggering signal.
LINE This setting is used when observing a signal with
power supply line frequency.
EXT External triggering signal applied to TRIG IN­
Plff becomes the triggering signal.
This setting is used when triggering with a special
Independently of the vertical axis signal.
@
INT TRIG select switch
This switch is used to select the internal triggering signal
source.
CH I The input signal applied to CH I becomes the
triggering signal.
CH2 The input signal applied to CH2 becomes the
triggering signal.
VERT For observing two waveforms, the sync signal
