编辑笔记：EE的7月刊可谓内容丰富，其中几篇涉及到了测试技术的三个前沿方向：LXI，测试脚本语言，DFT。
- 示波器
《示波器缩短发现问题的时间》
What is a scope? This is a difficult question to answer because the
definition of an oscilloscope continues to change. To a purist, the
only real oscilloscope is one that displays a waveform in direct
response to the input signal: in other words, an analog cathode-ray
oscilloscope with electrostatic vertical deflection plates driven
by an amplified version of the input.
- 数据采集
《在测试中如何将仪器的吞吐量和精度发挥到极致》
As test engineers continue to maximize production efficiencies,
they need to become more aware of ways to decrease test time and
the cost of test. Evaluating the speed vs. accuracy trade-offs
involved in making multichannel measurements is essential when
selecting the right type of DMM and switching hardware.
- 编程工具选择
《LXI系统开发工具》
With more LXI hardware coming to market and engineers taking a
closer look at this technology, questions from developers and
system integrators also involve software issues: What tools are
available to help me program an LXI system, and how do they differ?
For example, what debug facilities are at my disposal?
- 脚本语言
《LXI与脚本编程的好处》
Scripting is a powerful and convenient way to provide
programmability for instruments in test and measurement
applications. Script-based instruments provide architectural
flexibility, improved performance, and lower cost for many
applications. Scripting enhances the benefits of LXI instruments,
and LXI offers features that both enable and enhance scripting.
- 设计测试
《使用FPGA改进测试技术》
The concept of virtual instrumentation is more than 30 years old,
and its tenets are as true today as they were at its inception.
Test functionality is defined by the user in software, as opposed
to instrument functionality fixed by the equipment vendor using
application-specific modular hardware.
- 协议分析仪
《Understanding Gained One Layer at a Time》
Protocols are sets of rules. In data and communications networks,
they define how information must be organized for it to be
correctly interpreted. There are thousands of protocols in use
today, and they all have a life cycle.
- EMC测试
《Evaluating Lightning Susceptibility》
They say that lightning doesn’t strike the same place twice. Wrong!
The Empire State building has been struck thousands of times, so
often that it was used as a test object during early lightning
studies.
