[ C ] READOUT OPERATION
1 C R T surface readout
By
rotating the
INTEN
clockwise up to the very end, characters are displayed
on the C R T . Adjust the brightness as necessity requires.
The C H 1 and C H 2 scale factors are displayed in the
lower part of the C R T in accordance with setting of the
MODE select switch (jj) . The sweep scale factor is
displayed in the lower right part. B y pulling the
P O S I T I O N / P U L L x 1 0 MAG switch @ , a tenth scale
factor of the S W E E P TIME/DIV dial @ is displayed. The
calendar is displayed in the upper left.
NOTE: If the D A T A - O N / O F F switch on the bottom is set
to O F F position, the calendar is not displayed.
For the
calendar setting,
"Maintenance and Adjustment".

the INTEN (READOUT) controller
clockwise up to the very end. The readout func-
tion turns O F F , and the brilliance modulation on
the real-time waveform disappears.

Set the MODE select switch (jj)
the
C U R S O R S select switch
and t w o horizontal cursor lines are displayed on
the C R T and voltage difference between cursor
lines calculated in accordance with setting of
the C H 1 V O L T S / D I V dial (2) is displayed in the
upper right on the C R T . By setting the C H 1
V A R I A B L E controller (3) to the U N C A L posi-
tion, voltage ratio is displayed.

AV2:
Set the C U R S O R S select switch (31) to V 2 , and
voltage difference in accordance with the C H 2
range setting is displayed in the upper right on
the C R T similarly with the above.
AT:
S e t the C U R S O R S select switch (fj)
and t w o vertical cursor lines are displayed on
the C R T and time difference between the cur-
sor lines calculated based on the sweep scale
factor displayed in the lower right is displayed
in the upper right. By setting the

tion, time ratio is displayed.
MAT:
Set the C U R S O R S select switch (fj) to MAT,
and t w o vertical cursor lines are displayed on the
C R T and frequency between the cursor lines
calculated based on the sweep scale factor
displayed in the lower right is displayed in the up-
per right. B y setting the S W E E P VARIABLE con-
troller @
to the UNCAL position, phase dif-
ference is displayed.

In the case shown in Fig. 1 0 , the sampling pulse is
generated with a certain delay with respect to the input
signal, and the signal held by this sampling pulse becomes
the output signal.
In this figure, the period of the output signal is 1/12 of the
input signal.
NOTE: When the equivalent sampling is applied to an input
signal w i t h a low frequency, the dots of
waveform obtained will be coarse.
When triggering is inaccurate, the equivalent sampl-
ing operation will be abnormal and the waveform
displayed on the screen will be totally different from
the input signal.
