10.TIME RATIO MEASUREMENT USING CUR-
SORS
(CS-5130 only)
Duty
ratio
of square waves can be measured as follows:
1.
Supply signal
into
the INPUT terminal. Set the V. MODE
switch to the channel to be used, the
AC-GND-DC
selec-
tor switch to DC, and each switch so
that
ordinary sweep
is
displayed. Then adjust the
VOLTS/DIV
and
SWEEP
TIME/DIV
for
easy
waveform observation.
2.
Turn the
SWEEP
TIME
VARIABLE
switch on to adjust 1
cycle's
waveform to 5 divisions on the screen
with
the
^ •
POSITION
switches as necessity requires.
NOTE:
When the
SWEEP
TIME
VARIABLE
switch is set
to UNCAL, the
unit
is set to
RATIO
measurement
mode.
3.
Set the cursor mode to AT.
4.
Adjust the A
REF
cursor to the
left
of the two points to
be measured, and the A cursor to the
right.
