Limits the bandwidth to reduce display noise; filters the signal to eliminate noise and other unnecessary HF components. BW Limit On Off 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. Invert On Off 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 points by 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. 14
