Horizontal Settings
User can make some settings directly by tapping < or > next to options.
Time/DIV: Horizontal scale. If the waveform acquisition is stopped (using the
selector expands or compresses the waveform.
Y-T format: The conventional oscilloscope display format. It shows the voltage of a waveform record (on the
vertical axis) as it varies over time (on the horizontal axis).
Vertical Settings
The trigger determines when the Scopebox starts to acquire data and display a 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 clicking < 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.
BW Limit
• ON: Limits the channel bandwidth to 20MHz to reduce display noise.
• OFF: Get full bandwidth.
Invert
• ON: Invert the selected wave.
• OFF: Restore to the original display of the waveform.
Trigger setting
Trigger indicates that when certain waveform meets the conditions that are predefined according to the
requirements, the Scopebox acquires the waveform and its adjacent section, and then displays it on the
screen.
