testing working group is composed of technical personnel of the cabling company and the company to conduct on-going tests on all information points. For example, five types of tests are spot-checked according to 20% of all information points. After acceptance, technical personnel are responsible for routine maintenance and management of the network. Testing Instruments and testing standards Before testing, we need to select appropriate testing

. Error. Once an error occurs, it must be caused by your new code. In this way, compared with modifying the subject of the existing code The time and effort required for a positive error can be much less. The most noteworthy part of inheritance is that it does not provide a method for the new class. Inheritance is an expression of the relationship between the new class and the basic class. Yes. To sum up the relationship, "the new class belongs to one of the existing classes ". This expression

no trigger source is selected, the triggering system is disabled and the instrument runs freely: it will begin to measure the sample directly.Change the trigger sourceChanging the trigger source of an instrument in a multichannel oscilloscope software can be done in a variety of different ways:Open the Trigger Properties dialog box and use the source selector to select the trigger source you want. The advanced option provides the possibility to set multiple trigger sources for a combination.Tri

This article from: http://www.cnblogs.com/tony-yang/archive/2009/06/03/learnserialport.html C # has a lot of SerialPort learning materials on the Internet. Here I mainly sort out the materials used in my learning and classify them. First, we didn't have serial port hardware when learning, so we went to find a tool to simulate virtual serial ports. I'm using vspm.exe, http://www.skycn.com/soft/30517.html Start to learn about SerialPort. First, let's take a look at some basic knowled

-frequency grid, so that other nearby electronic instruments, equipment and household appliances are seriously disturbed. At present, due to the domestic microelectronics technology, blocking container parts production technology and magnetic materials technology and some technologically advanced countries still have a certain gap, so the cost can not be further reduced, but also affect the further improvement of reliability. Therefore, in China's ele

the problem of communication between electro-acoustic instruments proposed. MIDI is the most extensive music standard format in the arranger world, which can be called "computer-readable score". It uses the digital signal of the note to record music. A complete MIDI music is only dozens of KB large and can contain dozens of music tracks. Almost all modern music is crafted using MIDI plus a sound library. MIDI transmission is not a sound signal, but a

that the application may not have enough memory later. You can use the Instruments program to track code leaks. This program can be used either as a simulator or as an actual device. For more information about how to use Instruments, seeInstruments User Guide.

, you need to tell the development tool where to find the framework header file and other resources. In addition to the framework, Apple also publishes some technologies in the form of a standard shared library. Because IOS is UNIX-based, many underlying technologies of the operating system are sourced from open-source technologies, and many interfaces of these technologies can be accessed from the standard library and Interface directory. The SDK also contains the following important components

what to take, but the instruments we bought may not be more advanced than those outside China, it may never exceed. Why? Because it is a commodity instrument, it is available all over the world. You have it, I have it, and others have it. If you use it to do what others use it to do, it is difficult to rely on an instrument to reach a level higher than the international standard. Because of our understanding of the average person in electron microsco

Mobile phone testing is a big topic, involving hardware testing, software testing, and structural testing, such as stress resistance, wrestling, fatigue resistance, and low temperature resistance. The structural design is unreasonable, it will cause stress concentration and deformation of the shell. for mobile phone flip and lid failure, there are other serious problems. Hardware testing generally has strict physical and electrical indicators, as well as specialized
