Every company has the core technology that he publicizes publicly with underground, an Jielun has his idea in high-end oscillograph domain, the company values high-end oscillograph and new technology to be in more chip research and development, is not function and software side, because software is mixed,the function is duplicated very easily by the competitor. To high-end oscillograph, an Jielun thinks its core technology is a paragraph of more than 10 centimeters long circuit, include chip of a preamplifier and an ADC among them (modulus converter) , the odd chip that sampling of a 20G leads chip of its ADC amplifier (chip interior used 80 small ADC) , since was used on 54855A oscillograph 2002, still was not surmounted by any companies up to now, and preamplifier is to use radio frequency microwave to design a concept to be done, technology of microwave of this radio frequency is used on probe of the high end that need branch likewise. Arrive all the time today, on modulus converter, the series of new product DPO/DSA70000 that peaceful captures is 6.25G, two chip are being enclosed to go in inside a module is 12.5G, should achieve taller sampling to lead must use two or many ADC joining together, joining together connects a line additionally with respect to need, and in design of high speed circuit, often mean even line and join head lesser signal integrality to had been jumped over. Installing sound of nimble human relations to call them noise of oscillograph oneself this locality is the whole world is best, complete profit from its are compositive those who spend higher ADC design and technology of radio frequency microwave accumulate. But everybody also can see, the ADC that peaceful overcomes already improved 6.25G(to be used when oscillograph from 5G, enclose two 6.25G the) in a module, this is the process of a try to overtake each other in friendly emulation, the competition between manufacturer, of final benefit is an user.
Serial bus line makes high speed development trend
The development of oscillograph gets two factors normally restrict, one is the demand of the industry, another is the contest of competitors.
From the point of market itself, present electronic product volume is minorrer and minorrer, the chip that uses inside is compositive degree taller and taller, the use of serial signal gains ground more and more, its signal speed also is met faster and faster, at the same time the convenience for custom-built function, FPGA(spot but process designing array) also can gain ground more and more.
Serial to low speed signal, they often by compositive to a sheet piece in machine or a FPGA, also say, many control signal or other and logistic signal also can exist in the meantime, this meeting lets MSO (mixture signal oscillograph) popularize degree to rise.
High speed is serial bus line, USB2.0 has not overshot its fastigium, USB3.0 already be vividly portrayed. USB3.0 speed has bigger promotion, this meeting lets high-end oscillograph, especially the oscillograph sale of 12GHz bandwidth soars, it is USB3.0 just starts only, to comprehensive popularity, be afraid the time that needs 3 years at least. On the other hand, wireless technology is in all the time try to replace wired technique, although wireless USB technology, wireless HDMI does not have a large number of commercializing, already sample appears, this can support wireless signal with respect to requirement oscillograph manufacturer.
