waveform. When a trigger is set up properly, it can convert unstable displays or
blank screens into meaningful waveforms.
When the Scopebox starts to acquire a waveform, it collects enough data so that
it can draw the waveform to the left of the trigger point. The Scopebox continues
to acquire data while waiting for the trigger condition to occur. After it detects a
trigger, the Scopebox continues to acquire enough data so that it can draw the
waveform to the right of the trigger point.
User can make some settings directly by tapping < or > next to options.

Channel To select the channel source.
Volts/DIV
It is defined as “Volts/Division” and mainly used to
change the resolution.
Coupling
Trigger coupling determines what part of the signal
passes to the trigger circuit. AC, DC and Ground are
included:
AC: Blocks the DC component of the input signal.
DC: Passes both AC and DC components of the input
signal.
Ground: Disconnects the input signal.
Probe
When using a probe, the Scopebox allows you to select
the attenuation factor for the probe. The attenuation
factor changes the vertical scaling of the Scopebox so
that the measurement results reflect the actual voltage
levels at the probe tip.
