mode shall be used for v ideo signals. Waveform ca
not be displayed stably until setting correct trigger
mode
Please strive to set coupling to high-frequenc
inhibition and low-frequency inhibition display to
filter high low frequency noise triggered b
interference
5. To press RUN/STOP key without any dis play
To check if trigger mode of trigger menu is i
normal or single gear or not. It has to check if trigger
level is out of waveform scope or not
Trigger level shall be in the middle or trigger mode
shall be set to AUTO gear if yes
To press AUTO key for automatic setup as
above
6. Display speed will reduce after opening average
time sampling mode
In general speed will reduce normally if
average times exceed
7. Staircase waveform displa
s normal phenomenon, horizontal time base
can increase under super-low horizontal time base
gear so as to increase horizontal r esolution and
improve display
Possible display type is vector and sampli n
points can be connected for staircase waveform
display. Display type can be set to point displa
