嘿,我正在建立一个要购买的东西列表,以进行一些网站调查。
我选择了N9342C,我只是想知道我应该得到什么。 我必须测试的频率范围在148Mhz和6Ghz之间。 我应该尝试找一个全向天线吗? 我是否需要任何特殊的计算机软件来覆盖谷歌地图上的所有数据? 任何帮助将不胜感激。 对不起,如果我有点模糊,因为我有点被抛出这份工作。 以上来自于谷歌翻译 以下为原文 Hey I am setting up a list of things to purchase to do some site surveying. I have chosen the N9342C and am just wondering what else I should get. The Freq range I have to test is between 148Mhz and 6Ghz. Should I try and find a omnidirectional antenna? Do I need any special computer software to overlay all the data on google maps? Any help will be greatly appreciated. Sorry if I am a bit vague as I have kind of been thrown this job. |

Hi - 对于天线选择,N9311X RF套件提供一些与HSA配合使用的天线,包括全向或对数周期。
有关详细信息,请参阅产品手册:http://cp.literature.agilent.com/litweb/pdf/5990-5035EN.pdf请注意频率范围。 如果您需要的频率范围远远超出天线规格,您可能需要与其他供应商核实。 以下是使用GPS信息记录测量数据然后通过KML文件加载到Google Earth的方法:首先,在N9342C上安装GPS选项,然后使用仪器功能:1。标记记录功能。 它可以在单个频率上监控信号幅度。 按[标记] - > {更多} - > {记录开始}。 N9342C将开始将标记读数记录到* .CSV文件。 还将记录GPS信息。 然后使用HSA PC软件将CSV文件转换为通过标记记录保存的KML文件。 PC软件可从以下网址下载:http://www.home.agilent.com/agilent/software.jspx?ckey = 1927189&amp ;lc = eng& cc = US& nid = 1-11143.0.00& id = 1927189 2.安装 选项SCN,通道扫描仪选项。 它允许同时扫描最多20个不同的通道,N9342C计算每个通道的功率并在条形图或时间图中显示结果。 单键记录功能可为Google Earth和MapInfo等数据映射应用程序保存CSV或KML格式的结果。 有关详细信息,请参阅第71页的用户指南:http://cp.literature.agilent.com/litweb/pdf/N9342-90002.pdf我希望这有帮助 - 以上来自于谷歌翻译 以下为原文 Hi - For the antenna selections, the N9311X RF kit offers some antennas to work with HSA, including omni-directional, or logarithmic-periodic. Refer to the product brochure for details: http://cp.literature.agilent.com/litweb/pdf/5990-5035EN.pdf Note the frequency range. You may need to check with another vender if you need frequency range far beyond the antenna specs. Here are ways to log the measured data with GPS info and then load in Google Earth by KML file: First, install GPS option on N9342C, then utilize the instrument features: 1. Marker logging feature. It can monitor the signal amplitude at a single freq. Press[Marker]->{More}->{Logging start}. N9342C will start to record the marker readout to a *.CSV file. The GPS information will be recorded as well. Then use HSA PC software to convert the CSV file to KML file saved by marker logging. PC software can be downloaded from: http://www.home.agilent.com/agilent/software.jspx?ckey=1927189&lc=eng&cc=US&nid=-11143.0.00&id=1927189 2. Install option SCN, channel scanner option. It allows to simultaneously scanning a maximum 20 different channels, the N9342C calculates each channel’s power and displays the results in a bar, or time chart. A one-button logging function saves results in CSV or KML format for data mapping applications like Google Earth and MapInfo. Refer to User’ Guide on page 71 for details: http://cp.literature.agilent.com/litweb/pdf/N9342-90002.pdf I hope this helps - |

嗨,*********。
如您所见,网上有许多免费的转换工具。 但我不建议您使用它们来完成转换工作。 因为我一直认为在线免费工具没有付费的那么多专业功能。 据说其中一些可能含有一些病毒。 检查付费专业转换工具的一些免费试用,在您做出最终决定之前,首先使用C#.NET将pdf转换为图像。 我还建议你选择一种处理简单快捷的方法。 它可以为您节省大量时间。 请记住根据有关PDF转换的教程页面进行转换工作。 我希望你成功。 祝你好运。 最好的问候,潘---------------------------------------------- -------------------------------------------------- -------------------------------------------------- - *标签:*转换pdf; pdf到图像转换 以上来自于谷歌翻译 以下为原文 Hi, *********. As you see, there are many free conversion tools online. But I don't suggest you to use them to do with your conversion work. Because I always believe that the free tools online do not have so many professional functions as the paid ones. And it is said that some of them might contain some virus. Check some free trials of the paid professional conversion tools to convert pdf to image using C#.NET first before you make your final decision if possible. I also suggest you choose one whose way of processing is simple and fast. It can save a lot of time for you. Remember to do your conversion work according to its tutorial page about PDF conversion. I hope you success. Good luck.
