2. To connect signals for stable waveform display on
digital storage oscillograph.
Please refer to previous example for operation.
Please refer to previous chapter for adjustment of
horizontal time base and vertical gear.
3. To improve trigger by setting trigger coupling.
(1) To press MENU button in trigger area to display
trigger setup menu.
(2) To set trigger coupling to low-frequency
inhibition or high-frequency inhibition. Low-
frequency inhibition is to set a high-pass filter to
filter low-frequency signal component of less than
80kHz and allow pass through of high-frequency
signal component. High- frequency inhibition is to
set a low-pass filter to filter high-frequency signal
component of more than 80kHz and allow pass
through of low-frequency signal component. It can
be set to inhibit low-frequency or high-frequency
noise respectively to gain stable trigger
4. To reduce display noise by setting sampling
modes.
To adopt average sampling mode to eliminate
display of random noise to thinner waveform and
facilitate observation & measurement if waveform is
thickened by overlapping random noise to
measured signal. Signal details can be observed
conveniently by reduced random noise after gaining
average value. Detailed operation is as follows
To press ACQUIRE button in panel menu area to
display sampling setup menu
To press F1 key as
menu operation key to set obtainment mode to
average status. (As shown in following figure,)
please adjust average times by pressing F2 key as
menu operation key with step from 2 to 256 by
multiples of 2 so that waveform display can meet
observation & test equirements.
