测试测量 高精度温度测量铂电阻温度探测器(PRTDs)和ADC
Abstract: Many modern industrial, medical, and commercial applications require temperature measurements in the extended temperature rangewith accuracies of ±0.3°C or better, performed with reasonable cost and often with low power consumption. This article explains how platinumresistance ...
测试测量 能量收集系统的设计挑战
Modern electronic systems solve so many difficult problems that they often seem like magic. Nonetheless, these systems all have thesame basic limitation: they need a source of electrical power! Most of the time this is a straightforward challenge for the electronicdesigner, because there are many ...
测试测量 频谱仪测噪声系数
因为测量系统都用50欧姆, 如非特指, 以下所说的Gain均指功率增益(Power Gain). 但是一般的接收机的输入输出并非50欧姆, 因此有必要考虑电压增益(Voltage Gain).
测试测量 DN427开关控制器故障保护电压监测
 
Have you had the exasperating experience of a laptop orPDA defi antly not responding to your commands? Youfrantically press key after key, but to no avail. As hopeturns to anger (but just before you throw the company’slaptop through the window) you slam your fi nger againstthe on/of ...
测试测量 LT5528 WCDMA ACPR和AltCPR测量
 
ACPR (adjacent channel power ratio), AltCPR (alternatechannel power ratio), and noise are important performancemetrics for digital communication systems thatuse, for example, WCDMA (wideband code division multipleaccess) modulation. ACPR and AltCPR are bothmeasures of spectral regrowth. T ...
测试测量 低噪声电压基准的噪声测量
 
Frequently, voltage reference stability and noise defi nemeasurement limits in instrumentation systems. In particular,reference noise often sets stable resolution limits.Reference voltages have decreased with the continuingdrop in system power supply voltages, making referencenoise increa ...

This model simulates a CDMA2000 1xRTT Forward link (between Base Station and Mobile Station). In particular, it simulates the Radio Configuration 3 of a Forward Fundamental channel. The block CDMA2k: Initial settings allows you to set different parameters such as data rate, Power Control SubChannel ...
驱动编程 Addfilter is a command-line application which adds and removes filter drivers for a given drive or v
Addfilter is a command-line application which adds and removes filter drivers for a given drive or volume. It is intended to demonstrate how to insert a filter driver into the driver stack of a device. The sample illustrates how to do this by using the SetupDi APIs. The sample works on both x86 and ...
