在国内Protel软件一直大受欢迎,从DOS时代的Protel3.3(Autotrax 1.61)到现在具有EDA Client/Server (客户/服务器)即C/S“框架”体系结构的Protel98,它始终是PCB设计和制造领域的大众化工具软件,成为电子设计工作者们的首选。 在规范化的设计管理中,设计文件图样必须遵守相应的国家标准,如《电子产品图样绘制规则》、《设计文件管理制图》和《印制板制图》等,而由于Protel软件都是英文版,因此无法直接打印出符合国家标准的图纸,要将图纸规范化常用的方式是套打,即先将符合国家标准的表和汉字等打在纸上,再将该纸放入打印机,用Protel软件将印制板图打印其上,形成符合标准的文件,但这种做法效率很低,而且图形常会打偏,有时甚至会打反,经笔者试验,找到了一种简便的方法,使印制板图转换为AUTOCAD格式,再在AUTOCAD里一次性打印出符合标准的图纸。

ANALOG INPUT BANDWIDTH is a measure of the frequencyat which the reconstructed output fundamental drops3 dB below its low frequency value for a full scale input. Thetest is performed with fIN equal to 100 kHz plus integer multiplesof fCLK. The input frequency at which the output is −3dB relative to the low frequency input signal is the full powerbandwidth.APERTURE JITTER is the variation in aperture delay fromsample to sample. Aperture jitter shows up as input noise.APERTURE DELAY See Sampling Delay.bottom OFFSET is the difference between the input voltagethat just causes the output code to transition to the firstcode and the negative reference voltage. bottom Offset isdefined as EOB = VZT–VRB, where VZT is the first code transitioninput voltage and VRB is the lower reference voltage.Note that this is different from the normal Zero Scale Error.CONVERSION LATENCY See PIPELINE DELAY.CONVERSION TIME is the time required for a completemeasurement by an analog-to-digital converter. Since theConversion Time does not include acquisition time, multiplexerset up time, or other elements of a complete conversioncycle, the conversion time may be less than theThroughput Time.DC COMMON-MODE ERROR is a specification which appliesto ADCs with differential inputs. It is the change in theoutput code that occurs when the analog voltages on the twoinputs are changed by an equal amount. It is usually expressed in LSBs.
