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. Press the TRIG MENU button to display the Trigger Mode menu.
The following steps are different for different models.
PDS5022S,PDS6042S,PDS6062S,PDS6062T
6. Press the F1 menu selection button and choose Edge as the trigger type.
7. Press the F4 menu selection button and choose Single as the trigger mode.
8. Press the F3 menu selection button and choose Rising 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).
