1.
Set the probe menu attenuation coefficient to 10X and that of the switch in the
probe to 10X.
2.
Adjust the
VOLTS/DIV
and
SEC/DIV
knobs to set up a proper vertical and
horizontal ranges for the signal to be observed.
3.
Press the button
ACQUIRE
to display the
ACQUIRE Mode
menu.
4.
Press the
F2
menu selection button and choose
Peak Detect
.
5.

6.
Press the

as the trigger type.
7.

as the trigger mode.
8.
Press the

as the slope.
9.
Rotate the
LEVEL
knob and adjust the trigger level to the mid-value of the
signal to be measured.
10.
If the
Trigger State Indicator
at the top of the screen does not indicate
Ready
,
push down the
RUN/STOP
button and start
Acquire,
waiting the emergence of
the signal in conformity with the trigger conditions. If a signal reaches to the set
trigger level, one sampling will be made and then displayed in the screen. With
this function, any random occurrence can be captured easily. Taking the burst
burr of larger amplitude for example, set the trigger level to the value just
greater than the normal signal level, and then press the
RUN/STOP
button and
wait. When there is a burr occurring, the instrument will trigger automatically
and record the wave form generated during the period around the trigger time.
With the
HORIZONTAL POSITION
knob in the horizontal control area in the
panel rotated, you can change the horizontal position of the trigger position to
obtain the negative delay, making an easy observation of the waveform before
the burr occurs (see Fig. 66).
