Thedigital oscilloscope is an indispensable tool for anyone designing, manufacturing or repairing electronic equipment. In today's fast-paced world, engineers need the best tools available to solve their measurement challenges quickly and accurately. As the eyes of the engineer, digital oscilloscopes are the key to meeting today's demanding measurement challenges.

The usefulness of a digital oscope is not limited to the world of electronics. With the proper sensor, a digital oscilloscope can measure all kinds of phenomena. A sensor is a device that creates an electrical signal in response to physical stimuli, such as sound, mechanical stress, pressure, light, or heat. A microphone is a sensor that converts sound into an electrical signal.

Digital oscilloscopes are used by everyone from physicists to repair technicians. An automotive engineer uses a digital oscilloscope to correlate analog data from sensors with serial data from the engine control unit. A medical researcher uses a digital oscilloscope to measure brain waves. The possibilities are endless.

The four channel series includes even more functions, including: searching and navigating, on-screen Bode plot, 16 digital channels (Option), an external USB powered 25 MHz AWG module (Option) and an embedded application that allows remote control via web browser.

..The RIGOL MSO5000 Series Oscilloscope comes with a Bode plot function, which intuitively shows test curve and data. This can help engineers quickly determine system stability by analyzing parameters such as phase margin and gain margin.

..It integrates 7 independent instruments, including an oscilloscope, a 16 channel logic analyzer, a spectrum analyzer, an arbitrary wave generator, a digital voltmeter, a high-precision frequency meter and accumulator, and a protocol analyzer.

..The hardware waveform recording function adopts the segmented storage technology, which can selectively capture and store the user's concerned signal by setting the trigger conditions, and mark the time on the signal, which not only ensures the efficiency of acquisition, but also further expands the total time of waveform observation.

..The mso5000 series provides a real-time sampling rate of up to 8 GSa / s at 350 MHz bandwidth, with a sampling bandwidth ratio of about 23 times, which makes it a leader in the oscilloscope products of the same level, and has an ultra long waveform storage depth of 200 mpts.

..At the same time, observe and accurately measure the signals with large frequency difference between the two channels. The full memory hardware measurement can measure the accurate frequency value in the waveform with 340k rising edges

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]

Digital storage oscilloscope costs vary widely; bench-top self-contained instruments (complete with displays) start at US$300 or even less, with high-performance models selling for tens of thousands of dollars. Small, pocket-size models, limited in function, may retail for as little as US$50.[3]

The principal advantage over analog storage is that the stored traces are as bright, as sharply defined, and written as quickly as non-stored traces. Traces can be stored indefinitely or written out to some external data storage device and reloaded. This allows, for example, comparison of an acquired trace from a system under test with a standard trace acquired from a known-good system. Many models can display the waveform prior to the trigger signal.

Digital oscilloscopes usually analyze waveforms and provide numerical values as well as visual displays. These values typically include averages, maxima and minima, root mean square (RMS) and frequencies. They may be used to capture transient signals when operated in a single sweep mode, without the brightness and writing speed limitations of an analog storage oscilloscope.[4]

The displayed trace can be manipulated after acquisition; a portion of the display can be magnified to make fine detail more visible, or a long trace can be examined in a single display to identify areas of interest. Many instruments allow a stored trace to be annotated by the user.

Digital storage oscilloscopes may include interfaces such as a parallel printer port, RS-232 serial port, IEEE-488 bus, USB port, or Ethernet, allowing remote or automatic control and transfer of captured waveforms to external display or storage.

A personal computer-based digital oscilloscope relies on a PC for user interface and display. The "front end" circuits, consisting of input amplifiers and analog to digital converters, are packaged separately and communicate with the PC over USB, Ethernet, or other interfaces. In one format, the "front end" is assembled on a plug-in expansion card that plugs into the computer backplane. PC based oscilloscopes may be less costly than an equivalent self-contained instrument as they can use the memory, display and keyboard of the attached PC. Displays may be larger, and acquired data can be easily transferred to PC hosted application software such as spread sheets. However, the interface to the host PC may limit the maximum data rate for acquisition, and the host PC may produce sufficient electromagnetic noise to interfere with measurements.[5]

From the perspective of data capture, how is this achieved? If I wanted to implement a home-made digital device to capture high frequency analogue signals, what are my options? So far, I've only come up with some fairly useless ideas for designs!

Using a PIC microprocessor, the A/D sample rate on a 18f series I believe works out to be in the order of 1Mhz at 10 bit accuracy if I'm correct (?) And I can't imagine dedicated A/D chips being much better, how do modern scopes achieve frequencies in the GHz?

The entry level DSO Rigol 1052E (the one I own and 100 MHz capable with software change) uses an Analog Devices AD9288. This is a dual channel ADC with 8 bit parallel outputs and samples at either 40 or 100 million samples per second (depending on speed grad of chip). Although the Rigol is a 1 Gig samples per second, so I'm not sure if they are multiplexing these or what exactly is giving them 10x the samples of the single chip.

The AD9288 has bit-per-stage pipeline type converter for the 5 MSB bits and uses a 3-bit flash for the final 3 LSB. This makes sense, as the higher magnitude should be easier to convert fast with pipelines. As your ADC speeds go up, the number of bits sampled via flash conversion will increase, as steven said.

I presume they use Flash ADCs. These have the advantage that the conversion is immediate, while SA (Successive Approximation) ADCs like used in most microcontrollers perform an algorithm that requires a number of steps. A disadvantage of Flash ADCs is that they are rather heavy on hardware (an 8-bit ADC has 255 comparators), but most scopes don't have very high resolution. (Analog scopes often were 3% accurate, which translates to 5 bit.)

Jodes, your comment says you got your answer, but there's much more to the solution than Flash ADCs. Have a look at Agilent's Application Note, "Techniques to Achieve Oscilloscope Bandwidths of Greater Than 16 GHz." I used to work on that campus (but don't claim to have detailed scope experience). Agilent in Colorado Springs is the global hub of knowledge related to multi-gigahertz signal processing. They worked on a 32GHz solution for years and just started shipping last year. The active probes and microelectronics that do the signal processing are extremely sophisticated. Check out the entire library of documents related to Agilent's Infiniium 90000 X-Series high-performance DSO and DSA oscilloscope. Google it -- the URL is ugly and I'm not sure they offer a permanent link to the library page. You might also want to have a look at the related patents.
