View window extension
View window extension is to argument a section of
waveform to review image details conveniently.
Setup of view window extension can not be slower
than that of main time base.
As shown in above figure), it can be divided into 2
display areas under extension time base. Original
waveform is displayed for upper part. Selected area
can move horizontally by rotating horizontal
POSITION knob or increase or decrease by rotating
horizontal SCALE knob.
(
Waveform with horizontal extension in originally
selected waveform area is shown in lower part. (As
shown in above figure,) please pay attention that
resolution increases for extension time base by
comparing with main time base. Waveform displayed
by the entire lower party corresponds to area
selected for upper part so users can rotate horizontal
SCALE knob to reduce selected area and increase
extension time base, namely, horizontal extension
multiple of waveform.
The mode must be used for CH1 and CH2 at the
same time.
CH1 voltage will be displayed on X axle and CH2
