Basic Operation or not equal to the specified pulse width. ＜ , ＞ : Triggers the oscilloscope when the source signal pulse width is less than or greater than the specified pulse width. Slope Trigger: Judges trigger according to the time for rising or falling, more flexible and accurate than the Edge trigger. Alter Trigger: As a feature of analog oscilloscopes, it gives stable displays of signals at two different frequencies. Mainly it uses a specific frequency to switch between two analog channels CH1 and CH2 so that the channels will generate Alter trigger signals through the trigger circuitry.
DSO1000B(V) Series HandHeld Oscilloscope User Manual 28 Options Settings Comments Slope Source CH1 CH2 Select the input source as the trigger signal. Slope Rising Falling Select the slope type of signal. Mode Auto Normal Select the type of trigger. The Normal mode is best for most pulse width trigger applications. Coupling AC DC Noise Reject HF Reject LF Reject Selects the components of the trigger signal applied to the trigger circuitry. Vertical V1 V2 Adjust the vertical window by setting two trigger levels. Select this option and press F3 to choose V1 or V2. When = ≠ Select the trigger condition. Time 20ns to 10.0sec With this option highlighted, set the time span.
Options Settings Comments Alter Mode Auto Normal Select the type of trigger. Channel CH1 CH2 Push an option such as CH1, select the channel trigger type and set the menu interface. Below list options in submenus. Alter Trigger allows CH1 and CH2 to select different trigger modes and to display waveforms on a same screen. That is both channels can choose the following four trigger modes. Type Edge Slope Rising Falling Coupling AC DC select the components of the trigger signal applied to the trigger circuitry.
