Theory of Operation
Functional Model
The instrument has four high-level subsystems or processes (consisting of both hardware and
software functions) and the data that connects them:
Digital Signal Acquisition System. Acquires a waveform record from each signal you probe
using the following subsystems:
Input Channels. Conditions the input signal, primarily through the use of analog hardware,
before converting the signal to digital form.
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.
Time base System. Triggers the Acquisition system to start an acquisition cycle. In more
general terms, synchronizes the capturing of digital samples in the Acquisition system to the
trigger events generated from the Trigger system.
Acquisition System. Converts and stores the analog signal to a digital format.
Signal Processing and Transformation. Performs transformations or operations on user-
specified waveform data (channel, reference, and/or math waveforms). Automatic
measurements, spectral waveforms, and histogram generation are examples of signal
processing and transformation.
Display and UI. Provides output (and sometimes input) of instrument-data elements in a form
suitable to the user and also provides user input control.
