Chapter 5 To Trigger the Oscilloscope RIGOL
MSO7000/DS7000 User Guide 5-29
âš« >: triggers when the time difference (â–³T) between the specified edges of
Source A and Source B is greater than the preset time lower limit. Press Lower
to set the delay time lower limit in Delay trigger.
âš« <: triggers when the time difference (â–³T) between the specified edges of
Source A and Source B is smaller than the preset time upper limit. Press Upper
to set the delay time upper limit in Delay trigger.
âš« <>: triggers when the time difference (â–³T) between the specified edges of
Source A and Source B is greater than the lower limit of the preset time and
smaller than the upper limit of the preset time. Press Upper to set the delay
time upper limit in Delay trigger. Press Lower to set the delay time lower limit in
Delay trigger.
Note: The lower time limit must be smaller than the upper time limit.
âš« ><: triggers when the time difference (â–³T) between the specified edges of
Source A and Source B is smaller than the lower limit of the preset time or
greater than the upper limit of the preset time. Press Upper to set the delay
time upper limit in Delay trigger. Press Lower to set the delay time lower limit in
Delay trigger.
Note: The lower time limit must be smaller than the upper time limit.
Trigger Mode:
In the trigger control area (Trigger) on the front panel, press Mode to quickly switch
the current trigger mode. For details, refer to descriptions in "Trigger Mode".
Trigger Parameter Setting:
Set the trigger parameters (trigger holdoff and noise rejection) under this trigger
type. For details, refer to descriptions in "Trigger Holdoff" and "Noise
Rejection".
Trigger LEVEL/Threshold Level:
Rotate the Trigger
LEVEL knob to adjust the trigger level/threshold level. Refer
to "Trigger LEVEL/Threshold Level". The current trigger level/threshold level
value is displayed at the upper-right corner of the screen.
Setup/Hold Trigger
In Setup/Hold trigger, you need to set the clock source and data source. The setup
time starts when the data signal passes the trigger level and ends at the coming of
the specified clock edge; the hold time starts at the coming of the specified clock
edge and ends when the data signal crosses the trigger level again, as shown in the
figure below. The oscilloscope triggers when the setup time or hold time is smaller
than the preset time.
