control area on the panel can be rotated to alter
horizontal trigger position so as to gain negative
delay trigger with different length to facilitate
observation of waveform before burring.
Figure 3-3 Single signal
You can adjust setup of digital storage oscillograph
for overlapping of random noise to tested signal so
as to filter or reduce noise and avoid disturbance to
ontology signal during measurement. (Please refer
to following figure for waveform.)
Figure 3-4 To reduce random noise of signals
Operation steps are as follows:
1. As shown in previous example, please set
attenuation coefficient of probe and CH1 channel.
The fourth example: To reduce random noise of
the signal
