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: Turn on the invert function.
