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

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 1 -2 -5 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.
