Automatic setup of waveform displa
UTD2000/3000 series digital storage oscillograp
has automatic setup functions. It can adjus t vertical
deflection coefficient, scanning time base and
trigger mode automatically according to i nput
signal for the most appropriate waveform display
Frequency of measured signals shall be more tha
or equal to 50Hz and duty cycle shall exceed 1%
according to automatic setup requirements
1. Connect measured signals to s ignal i nput
channel
2. Press [AUTO] button so that digital storage
oscillograph can set ver tical deflection coefficient
scanning time base and trigger mode
automatically. They can be adjusted again after
careful observation and automatic setup so that
waveform display can realize the best effect
s shown in the following figure, there are a series
of keys and knobs in v ertical control area. Please
introduce usage of vertical setup gradually as
