The financial turmoil and Spring Festival approaching the blundering vortex and digital era of rapid steps forward test and measurement. On January 13, 2009 in Beijing kerry center), and the newly issued fired first, the company marketing manager SunZhiJiang introduces current fastest oscilloscope system, whether this will open test oscilloscope and measurement and an oscilloscope war industry?

Oscilloscope is sometimes called "electronic engineer," it is a screwdriver for various tasks of the basic tools. As a general tests measuring instrument, oscilloscope in communication, industrial automation, education, computer, national defense, aerospace and other fields of status reigns.

Sadie advisers expected over the next five years, China will be in 2007 oscilloscope market based on the steady development trend continued growth. 2008 China oscilloscope market scale is close to 10 billion yuan. 2012 oscilloscope market scale in China is expected to break 20 billion yuan. The cold winter in semiconductor industry, like a warm oscilloscope market of oasis, bring faith and hope.

From the fifth in the market looking

If the current digital era of test and measurement is divided into digital RF technology, digital video technology, high-speed serial technology, embedded systems and next generation network five parts. So, test and measurement performance oscilloscope index changing factors should be who?

Analysis: "since SunZhiJiang available bus interface of 8-10 years, already from parallel to high-speed serial technology, data transfer rate also quickly from 3Gb/s/s > > 6Gb has 12Gb/s/s". With all the standardized process industry steadily, high-speed serial technique has achieved a plug and play, interoperability and its prospect of consumer electronics with sustainable growth and continued development." However, the serial technology way forward seems not light avenue, "we will face is more complex, signal system and the development cycle more small cushion etc many more challenges.

Cloud and mist anticipation

Through analyzing the design cycle, SunZhiJiang said: "for each with an oscilloscope serial data flow with rapid complex of engineers, layer upon layer inspection and testing, calibration can be used to describe the pain. It usually will cost them 90% of the time for repeated debugging." Obviously, continuously shorten the development cycle of cannot tolerate this process has how redundancy, from the same test process liberation? Quickly and can trigger positioning information specific functions can provide best insight.

Trigger system is composed of four oscilloscope system, but it is easy to ignore. Some high-speed serial analysis system for high-speed serial data stream provides software functions, this method had triggered the bits omissions may reached $10 million! Based on the hardware and the serial trigger technology can real-time oscilloscope monitoring data, find a sequence of interest. It examines every bits, the system will be the first occurs in sequence, triggering collection missing waiting bits. Like a precise intelligent hand, cloud and mist, anticipation.

The important role of ignored - effective bits (ENOB)

SunZhiJiang cited examples, in such a system, if we put when measuring the oscilloscope likened to a weighing scales, so bad in the low (ENOB) is in the first before weighing scales put on some weight. Today, more and more small cushion work fast digital design more vulnerable to the new "weight". A ENOB low oscilloscope is likely to lead to expensive "pseudo" test failure caused by specific, originally designed for the product performance test test "failure". This "failure" is not the problem caused by the design itself, but his error in test oscilloscope cushion of a large proportion, the measured results exceeded can tolerate extreme. False readings may make the development team to spend a lot of time, and finally a big bend around trying to solve the "problems" does not exist.

"ENOB" is a very comprehensive index, in a certain extent covers all digital oscilloscopes have many errors, such as offset error, error, nonlinearity, gain noise, etc. However, as a practical index, "but hasn't been ENOB" most attention, but actually manufacturer of low "ENOB" will make net measuring resolution, may give already very narrow tests, and even some errors allowance "serious mistakes" measurement results.

Gold status "gold" probe

"No," a bare oscilloscope probe, often talked about SunZhiJiang must repeat the oscilloscope system play an important role in all, when we focus on bandwidth and frequency response rate, such problems, small probe seems to become an option, but in fact, no one has strong performance of relies on this small oscilloscope probe dc power supply connection capacity.

Now, the encapsulation of high-speed circuit has forced the probe to the limit access, engineers may need in difference measurement, single measurement and common-mode random switching between the probe measurement, without moving probe connection. Engineers can detect three, use a probe for three different measurement, not only need more like before, and more to improve work efficiency.

Superior products provide the oscilloscope source power, hope the speed and passion to dispel cold and semiconductor industry to develop steadily.
