The oscilloscope has four high-level subsystems or processes (consisting of both
hardware and software functions) and the “data” that connects them:
H
Digital Signal Acquisition System. Acquires a waveform record from each
signal you probe using the following subsystems:
H
Input Channels. Conditions the input signal, primarily through the use
of analog hardware, before converting the signal to digital form.
H
Trigger System.
Recognizes a specific event of interest on the input signal
and informs the Time base system of the occurrence of the trigger event.
