Digital oscilloscopes can be classified into two primary categories: digital storage oscilloscopes and digital sampling oscilloscopes. [1] [2] Newer variants include PC-based oscilloscopes (which attach to a PC for data processing and display) and mixed-signal oscilloscopes (which employ other functions in addition to voltage measurement).
Under the Sony-Tektronix name, the 300 series oscilloscopes were lightweight and totally portable. They replaced the model 321/321A oscilloscopes. Examples of the Sony/Tektronix models were 314, 323, 335 and 370. Tektronix 7854 oscilloscope with other equipment. During the early 1970s, Tektronix made a major design change to their oscilloscopes.
A Tektronix TDS210 digital oscilloscope. A digital storage oscilloscope (DSO) is an oscilloscope which stores and analyses the input signal digitally rather than using analog techniques. It is now the most common type of oscilloscope in use because of the advanced trigger, storage, display and measurement features which it typically provides. [1]
Modern digital oscilloscopes set the measurement parameters and calculate/display the signal values automatically. An oscilloscope, (formerly known as an oscillograph), (informally scope or O-scope) is a type of electronic test instrument that graphically displays varying voltages of one or more signals as a function of time. Their main purpose ...
The Tektronix 2400 Series oscilloscopes were perhaps the most powerful instruments of their time, with the 2445, 2465, and 2467 being the top-end models and the 2430 series of digitizing storage oscilloscopes providing digital storage. They combined high bandwidth and sampling rates with automation features and waveform processing capabilities.
DSOs also led to the creation of hand-held digital oscilloscopes, useful for many test and field service applications. A hand held oscilloscope is usually a real-time oscilloscope, using a monochrome or color liquid crystal display for its display. Due to the rise in the prevalence of PCs, PC-based oscilloscopes have been becoming more common.
Keysight Technologies, Inc. is an American company that manufactures electronics test and measurement equipment and software. The name is a blend of key and insight. [2] [4] The company was formed as a spin-off of Agilent Technologies, which inherited and rebranded the test and measurement product lines developed and produced from the late 1960s to the turn of the millennium by Hewlett-Packard ...
For example, a Tektronix P6139A input impedance starts falling above 10 kHz and is about 100 ohms at 100 MHz. [9] A different probe technique is needed for high frequency signals. A high frequency oscilloscope presents a matched load (usually 50 ohms) at its input, which minimizes reflections at the scope.
