Sweep: The sweep mode determines how the Scopebox behaves in
the absence of a trigger event. The Scopebox provides three trigger
modes: Auto, Normal, and Single.
• Auto: It allows the Scopebox to acquire waveforms even when it
does not detect a trigger condition. If no trigger condition occurs
while the Scopebox is waiting for a specifi c period, it will force itself
to trigger.
When forcing invalid triggers, the Scopebox can not synchronize
the waveform, and then waveform seems to roll across the display.
If valid triggers occur, the display becomes stable on the screen.
• Normal: This mode allows the Scopebox to acquire a waveform
only when it is triggered. If no trigger occurs, the Scopebox keeps
waiting, and the previous waveform, if any, will remain on the
display.
• Single: In this mode, it only acquires the waveform that generates
for the fi rst time the trigger conditions are met, and then stops after
fi nishing capture.
Source: Select which channel as trigger signal.
Slope:
• + : Trigger on rising edge
• - : Trigger on falling edge
High Freq Rejection: Reject high frequency signals when selected.
2) If Pulse Width trigger is selected (Pulse trigger occurs according to
the width of pulse. The abnormal signals can be detected through
setting up the pulse width condition):

7.3.4.2 Auto
The Scopebox has an Auto feature that sets up the Scopebox
automatically to display the input signal in a best fi t.
Tap
, the Scopebox may change the current settings to display the
signal. It automatically adjusts the vertical and horizontal scaling, as
well as the trigger coupling, position, slope, level and mode settings.

<1> Calibration
This option adjusts the Scopebox’s internal circuitry to get the best
accuracy. Use this function to calibrate the Scopebox’s vertical and
horizontal systems.
