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
To reduce average times.
7. Staircase waveform displa

A
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
