STK调节器(中英文混排)
STK 系列低压动态无功调节器（STK series low voltage dynamic reactive regulator）产品概述（Specification）STK动态无功调节器是一种新型的可控硅制电容投切开关，即TSC动态投切开关。
具有电压过零时刻投入，不产生涌流；电流过零时刻切除，不产生高压；STK dynamic reactive r egu lato r i s a new kind of SCR control capacitance switching. It turn on at the moment voltage pass zero, no surge-current; and it cut off at the moment current pass zero, 谐波导通，不产生谐波，无声运动，是替代交流接触器的一种新型开关。
STK系列动态无功调节器集成了晶闸管、触发板、散热器、轴流风机、温度控制、no high voltage; full-wave conduction,no harmonic,and noiselessness, a new kind of switching which substitutes the ac contactor. STK series switching integrate thyristor、trigger board、接线端子等器件，用户只需上端接电源，下端接电容，二次端接控制器信号及零线，便可使用。
接线简洁方便，用于快速动态补偿电容投切。
radiator、axial flow fan、temperature control、wring terminal,and so on. Connect the up port with supply, down port with capacitance, secondary port with the controler single and zero line, then EFT群脉冲抗干扰可达4000V的A级（国际电工标准最高级），功能完备。

Reverse connection of supply voltage can cause destruction.2. The input voltage should be allowed to input without damage or destruction. Even during the transition periodof supply voltage, power on/off etc., this specification should be kept. The normal operation will establish when the both inputs are within the Common Mode Input Voltage Range of electrical characteristics.3. This specification is the voltage which should be allowed to supply to the output terminal from externalwithout damage or destructive. Even during the transition period of supply voltage, power on/off etc., this specification should be kept. The output voltage of normal operation will be the Output Voltage Swing of electrical characteristics.4. Thermal derating factor is –7.6 mW/°C when ambient temperature is higher than 50°C.5. Thermal derating factor is –5.5 mW/°C when ambient temperature is higher than 25°C.6.

The nominal frequency f N is fixed on 456,49 MHz without tolerance.The given values for the relative attenuation a rel and for the group delay ripple have to be reached at the frequencies given below also if the centre frequency f o is shifted due to the temperature coefficient of frequency TC f in the operating temperature range and due to a production tolerance for the centre frequency f o .D a t atyp. value Variation/ Limitation______________________________________________________________________________________________________Insertion lossa e = a max 3dB max.5dB (Reference level)______________________________________________________________________________________________________Nominal frequency f N -456,49MHz______________________________________________________________________________________________________Centre frequency f 0456,49MHz -______________________________________________________________________________________________________3 dB - bandwidthBW 280kHz -______________________________________________________________________________________________________Usable signal bandwidth -min.f N ± 10 kHz______________________________________________________________________________________________________Relative attenuation a rel f N + 910 kHz min.52dBf N ± 0,7 MHz ... f N ± 10 MHzmin. 40dB ______________________________________________________________________________________________________Temperature coefficient of frequencyTC f -0,036 ppm/K 2-______________________________________________________________________________________________________Frequency inversion temperature + 25 °C______________________________________________________________________________________________________Operating temperature range - 10°C ... + 50°C______________________________________________________________________________________________________Generated:Checked / approved:______________________________________________________________________________________________________VI TELEFILTER Vectron International, Inc.Potsdamer Straße 18 267 Lowell Road D 14 513 TELTOW / Germany Hudson, NH 03051 / USA Tel: (+49) 3328 4784-52 / Fax: (+49) 3328 4784-30 Tel: (603) 598-0070 Fax: (603) 598-0075Construction and pin connection(All dimensions in mm)50 Ω test circuit 11,2,3,46,7,8,950 Ω test circuit 21,2,3,46,7,8,9Stability CharacteristicsAfter the following tests the filter shall meet the whole specification:TFS 456 C tft L1123456789101Ground 2Ground 3Ground 4Ground 5Output 6Ground 7Ground 8Ground 9Ground 10Input______________________________________________________________________________________________________VI TELEFILTER Vectron International, Inc.Potsdamer Straße 18 267 Lowell Road D 14 513 TELTOW / Germany Hudson, NH 03051 / USA Tel: (+49) 3328 4784-52 / Fax: (+49) 3328 4784-30 Tel: (603) 598-0070 Fax: (603) 598-00751.

The family includes single (THS4521), dual (THS4522), and quad (THS4524)(1) versions.
These fully differential op amps feature accurate output common-mode control that allows for dc-coupling when driving analog-to-digital converters (ADCs). This control, coupled with an input common-mode range below the negative rail as well as rail-to-rail output, allows for easy interfacing between single-ended, ground-referenced signal sources. Additionally, these devices are ideally suited for driving both successive-approximation register (SAR) and delta-sigma (ΔΣ) ADCs using only a single +3V to +5V and ground power supply.
数字频率计的设计 毕业设计论文
数字频率计的设计摘要:本论文是一种直接用十进制数字来显示被测信号频率的测量装置。
它不仅可以测量正弦波、方波、三角波的频率，而且还可以测量其它各种单位时间内变化的物理量的频率。
该频率计是首先将被测信号变成脉冲信号，其重复频率等于被测频率。
时钟电路提供标准的时间脉冲信号。
闸门电路由标准秒信号进行控制，当闸门信号为高电平时，闸门开通，被测信号的脉冲通过闸门送入计数显示电路进行显示；当闸门信号为低电平时，闸门关断，计数器没有时钟脉冲输出，计数器停止计数。
关键词:频率显示闸门秒信号引言随着无线电技术的发展与普及，“频率”已成为广大群众所熟悉的物理量。
调节收音机上的频率刻度盘可以使我们选听到自己所喜欢的电台节目；调节电视机上的微调旋钮可使电视机对准电视台的广播频率，获得图像清晰的收看效果，这些已成为人们的生活常识。
人们在日常生活、工作中更离不开计时。
学校何时上、下课？工厂几时上、下班等这些都涉及到计时。
频率、时间的应用，在当代高科技中显得尤为重要。
例如，邮电通讯，大地测量，地震预报等等，都与频率、时间密切相关，只是其精密度和准确度比人们日常生活中的要求高得多罢了。
本次设计主要采用计数法制成一个测量范围在0～9999Hz的频率计。
该频率计闸门信号的采样时间为1s，并采用4位数码管显示。
它不仅可以测量正弦波、方波、三角波的频率，而且还可以测量其它各种单位时间内变化的物理量的频率。
一、数字频率计的组成数字频率计电路主要由串联型稳压电源、整形电路、10分频电路、时钟电路、闸门形成及控制电路、计数显示电路等组成。

基于STK的GNSS系统的定位精度分析
基于STK的GNSS系统的定位精度分析刘周巍【摘要】利用STK对GNSS系统当中的GPS、GLONASS、BDS系统构建仿真星座模型,比较GPS、GLONASS、BDS系统的可见卫星数和DOP值.对三个系统进行系统间混合组合形成新的系统,组合系统有GPS/GLONASS、GPS/BDS、BDS/GLONASS和BDS/GPS/GLONASS,对组合系统进行仿真实验比较分析不同截止高度角下的可见卫星数变化和DOP值.对不同系统的区域定位性能进行了研究,研究结果表明了在GNSS系统不同组合系统的定位精度中,GPS/BDS/GLONASS 的组合精度最高,GPS/BDS的组合是双系统中定位精度最优的,而单系统中BDS是定位精度最优的.【期刊名称】《软件》【年(卷),期】2018(039)008【总页数】6页(P104-109)【关键词】GNSS;精度因子(DOP);STK;多星座;仿真实验【作者】刘周巍【作者单位】昆明理工大学国土资源工程学院,云南昆明 650093【正文语种】中文【中图分类】TP391.9全球卫星导航定位系统主要包括GPS、GLONASS、GALILLEO和BDS，在本文中主要研究了GPS、GLONASS、BDS和组合系统。
对导航星座而言，系统提供的定位几何是影响导航精度的一个重要因素。
一般导航系统的定位几何可以用精度衰减因子DOP（Dilution of precision）来描述，定义为用户等效距离误差UERE（User Equivalent Range Error）到最终定位误差或定时误差的放大系数，它反映了观测源几何位置对定位误差的影响[1]。
在卫星导航系统中，精度衰减因子DOP中的几何精度因子GDOP对接收机精度有很大影响。
为了评估定位精度，通常需要计算导航系统的GDOP值[2]。
在本文中，利用STK建立GPS、GLONASS、BDS和组合系统的空间卫星星座模型，对精度衰减因子（DOP，Dilution of precision）中的几何精度衰减因子（GDOP，Geometry Dilution of precision）进行研究分析，进而分析不同条件下的GPS、GLONASS、BDS、GPS/GLONASS、GPS/BDS、BDS/GLONASS和GPS/BDS/GLONASS的定位精度。
