The invert function turns the displayed waveform 180
degrees, with respect to the ground level. When the
oscilloscope is triggered on the inverted signal, the
trigger is also inverted.
Trigger System
The trigger determines when the oscilloscope begins to acquire data and display a
waveform. Once a trigger is properly set up, the oscilloscope can convert unstable
displays or blank screens to meaningful waveforms.
The triggering mode of this series oscilloscope is edge trigger.
Edge trigger distinguishes the trigger pointsby seeking the specified edge (rising,falling,
rising & falling) and trigger level.
Press Trig button to enter trigger menu.
Trigger Source: Select the trigger source signal to CH1 or CH2. You can use the trigger
source options to select the signal that the oscilloscope uses as a trigger.
Slope: Select the trigger slope to rising, falling, rising & falling.
Trigger Mode: You can select the Auto or Normal mode to define how the oscilloscope
acquires data when it does not detect a trigger condition. Auto Mode performs the
acquisition freely in absence of valid trigger. It allows the generation of untriggered
waveforms with the time base set to 100ms/div or slower. Normal Mode updates the
displayed waveforms only when the oscilloscope detects a valid trigger condition. Before
this update, the oscilloscope still displays the old waveforms. This mode shall be used
when you want to only view the effectively triggered waveforms. In this mode, the
oscilloscope displays waveforms only after the first trigger. To perform single trigger
acquisition, the trigger mode can be set to "single". When triggered, a single waveform is
acquired and then stop.
Force Trigger: Used to complete an acquisition regardless of an adequate trigger signal.
This button becomes useless if the acquisition is already stopped.
Trigger Level: It sets the amplitude level the signal must cross to cause an acquisition
when using the Edge or Pulse Width trigger. Press Trig button to enter, and press Up or
Down direction keys to change the trigger level.
