Mainly for analogue oscilloscope

20 the 1940s is electronic oscilloscope rise era, radar and TV development needs the good performance of wave observation tools, bear the successful development of synchronous oscilloscope 10MHz bandwidth, it is the foundation of modern oscilloscope. In the 1950s and the advent of semiconductor electronic computers, promote the bandwidth to 100MHz electronic oscilloscope. In the 1960s America, Japan, England, France in electronic oscilloscope development are different, the contribution of sampling oscilloscope 6GHz bandwidth, bandwidth dc power supply and 4GHz wave wave, 1GHz storage and wave tube, Portable, plug-in type oscilloscope become series products. In the 1970s analog electronic oscilloscope peak, a series of spectra, bandwidth 1GHz multifunctional plug-in type oscilloscope marks at high level of science and technology, digital circuit for testing and add logic oscilloscope and digital waveform recorder. Since no greater analogue oscilloscope, started to make progress in digital oscilloscopes, Britain and France, even from the oscilloscope market in America, leading technology by Japanese cheap product production.

Analogue oscilloscope, need to increase bandwidth and wave tube, the vertical and horizontal scan in an all-round way. Digital oscilloscopes to improve bandwidth only needs to improve the front of A/D converter performance of wave, and no special requirements of scanning circuit. And shimei digital wave can make full use of memory, storage and handling, as well as various trigger and preliminary trigger ability. In the 20th century 80's digital oscilloscopes, great achievements, instead of comprehensive analogue oscilloscope, analogue oscilloscope gradually from front to back.

But in the early development of some characteristics of analogue oscilloscope, digital oscilloscopes didn't have the:

Simple operation, all in all, can be found on dc power supply the panel, waveform, digital oscilloscopes timely response to a long time often.

The vertical resolution, high grade, continuous and infinite resolution digital oscilloscopes generally only eight to ten.

Second, data update quickly: a waveform, catch hundreds of digital oscilloscopes catch dozens per wave.

2008 real-time bandwidth and real-time display: continuous wave with a single wave of bandwidth, digital oscilloscopes bandwidth is closely related with the sampling rate is not high, sampling rate should be calculated by interpolation, appears easily confused waveform.

In short, analogue oscilloscope for engineering and technical personnel, the waveform is provided in the bandwidth can be very relieved. Human facial nerve is very sensitive eyes vision in moments, screen reflected wave to judge the brain changes, can be perceived. Therefore, started by users of analogue oscilloscope.

Metaphase digital oscilloscopes clueless

In the 1980s, the digital oscilloscopes in transition, there are many places to improve, the United States and the products of TEK company of HP to contribute to the development of digital oscilloscopes. They then discontinued analogue oscilloscope, and only good digital oscilloscopes production performance. Into the 1990s, digital oscilloscopes, in addition to improving the bandwidth to 1GHz above, more important is its overall performance beyond analogue oscilloscope, especially in the new century, digital oscilloscopes functions strengthened, bandwidth 10GHZ has risen to. Appear alleged digital oscilloscopes MoNiHua phenomenon, in other words, to absorb the analogue oscilloscope, make digital oscilloscopes better use.

Digital oscilloscopes sampling rate in the first, from the initial sampling rate is equal to twice to increase the bandwidth, five times, even ten times, corresponding to the distortion sinusoidal sampling introduced from 1% to 3% even lower 100%. The sampling rate is 1GHz bandwidth 5GHz/s, even 10GHz/s.

Secondly, improve the update rate of digital oscilloscopes, reach the same level, analogue oscilloscope top 40 million per waveform signal and contingency observation ability to capture burr pulse greatly.meantime.

Again, use more CPU speed signal processing capacity, from multiple menu with measuring parameters adjustment, improvement for simple, even completely automatic adjustment knob, use the same with analogue oscilloscope.

Finally, digital oscilloscopes and analogue oscilloscope has the screen display, the rays of three-dimensional wavelength, namely shows signal amplitude, time and amplitude of time. Has the function of digital oscilloscopes called digital oscilloscopes or digital oscilloscopes fluorescent atagi model and that.
