20 Channel Toolbar Channel 1 & 2 Configuration (Trigger Configuration)

21 CHANNEL TOOLBAR CHANNEL 1 & 2 (TRIGGER CONFIGURATION) Trigger Mode: Normal – triggered on specified condition Auto – triggered on trigger condition, self starts in 2 seconds None – the acquisition is started without a trigger

22 CHANNEL TOOLBAR CHANNEL 1 & 2 (TRIGGER CONFIGURATION) Source: Channel 1 Channel 2 Digital AWG – 1 AWG – 2 Analyzer Patterns External – 1 External - 2

23 CHANNEL TOOLBAR CHANNEL 1 & 2 (TRIGGER CONFIGURATION) Type of Trigger: Simple – is an edge trigger where the filter, hysteresis, and holdoff parameters are configured automatically. Level is set to 10% of the selected trigger channel range

24 CHANNEL TOOLBAR CHANNEL 1 & 2 (TRIGGER CONFIGURATION) Type of Trigger: Edge + slope-condition control

25 CHANNEL TOOLBAR CHANNEL 1 & 2 (TRIGGER CONFIGURATION) Type of Trigger: Pulse, will trigger if pulse has a smaller/larger length than the one set by the user. Set for Less then 200 usec.

26 CHANNEL TOOLBAR CHANNEL 1 & 2 (TRIGGER CONFIGURATION) Type of Trigger: Pulse, will trigger if pulse has a smaller/larger length than the one set by the user. Set for more then 200 usec.

27 CHANNEL TOOLBAR CHANNEL 1 & 2 (TRIGGER CONFIGURATION) Type of Trigger: Transition - the transition time of a signal as compared with a specified length

28 CHANNEL TOOLBAR CHANNEL 1 & 2 (TRIGGER CONFIGURATION) Type of Trigger: Transition - the transition time of a signal as compared with a specified length

29 CHANNEL TOOLBAR CHANNEL 1 & 2 (TRIGGER CONFIGURATION) Trigger Hysteresis – low and high leveles are determined to avoid bouncing caused by signal noise and also to specify the transition trigger conditions, 20 volts to 1mv and zero volts in steps

30 CHANNEL TOOLBAR CHANNEL 1 & 2 (TRIGGER CONFIGURATION) Trigger Hysteresis

31 CHANNEL TOOLBAR CHANNEL 1 & 2 (TRIGGER CONFIGURATION) Trigger Holdoff – a adjustable time period during which the oscilloscope will not trigger. this is useful when triggering on complex waveform shapes, so the oscilloscope triggers only on the first eligible trigger point. Time range from 1 hour to 100nsec., in 1 – 2 – 5 steps and zero sec.
