Press the
F2
menu selection button and choose
Single
as the trigger
mode.
Rotate the
LEVEL
knob and adjust the trigger level to the mid-value of
the signal to be measured.
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 presses the
RUN/STOP
button and waits. 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.105).
