Keysight 不需要激活的官方免费版本BenchVue

2024/01/03

之前发过一个如何安装、激活BenchVue软件的视频，我已经在置顶的评论里说了，官方关掉了激活通道，那个方法已经行不通了，但是还是有人留言、私信问各种关于激活的问题，实际上只有两条路：1、像授权经销商购买软件License，享受官方的售后服务2、直接下载没有服务但是免费的Basic版本BenchVue软件第一条路大家可以自行寻找你所在城市的授权经销商咨询，第二条路我指给你，但是因为官方是不提供技术服务的，所以你也不要指望我这里能有多少支持能力。官方对Basic版本和机器内置License版本的差异对比 Basic版本的官网地址如下：https://www.keysight.com.cn/cn/zh/lib/resources/technical-specifications/pathwave-benchvue-basic.html首先免费版本支持的仪器种类并不完整，但是也覆盖了常见的各种仪器，如果这个列表里没有你想要的产品，那么恭喜你，请回头走第一条路。Basic版本的BenchVue软件支持的仪器类型如果你想要的软件刚好在列表中，那么恭喜你，点击红色字体的链接就会跳转到相应的下载页面，安装就是了。数据采集器的Basic版软件这些软件里有些有两种不同的版本，一个叫Standalone版本，一个叫Platform版本，其实就是顾名思义，一个就是独立运行的，一个就是嵌入在BV框架内部的，实际使用起来有一些差别，主要是有些新型号的仪器只能用Standalone版本，能用哪个就用哪个吧，两个都安装没有关系。但是如果之前安装过内置序列号激活的，可能需要先把老版本的软件卸载掉，再重新安装Basic版本的软件，已经在一些客户那边发现了冲突的问题。如果说你的安装电脑没办法实时联网，需要离线的安装包，这次Basic版本的BenchVue也提供了离线版本的下载离线安装包下载页面正常情况下，BenchVue的下载器会自动安装Connection Expert驱动库软件，但是有可能在某些情况下自动下载的并不是最新版本，那么可以手动下载最新的Connection Expert软件，特别是在WIN11上遇到无法通过USB连接仪器的问题，那大概率安装最新版驱动库软件就可以解决。Connection Expert驱动库软件官方地址如下：https://www.keysight.com.cn/cn/zh/lib/software-detail/computer-software/io-libraries-suite-downloads-2175637.html打开网页往下拉，找到IOLS 2023的按钮，点击下载。不要管这个按钮是第几个，要看名字对的那个，IOLS=IO Libraries Suite也就是驱动库软件，其他的不需要。 IOLS软件下载按钮基本上这一套组合拳下来，BV软件都能跑起来了，希望各位同学用好手上的仪器，提高学习和工作的效率。...

NetAlly EtherScope nXG便携专业智能网络测试仪 - 透视 Wi-Fi使用中的干扰

2023/08/31

无线Wi-Fi因为其便利性、移动性、灵活部署、可扩展性和便于施工广受青睐。但要充分发挥无线Wi-Fi的性能，也非易事，一个重要的管理内容就是无线电空口资源的使用效率。一般来说，不同区域或国家都会有相应的无线电管理委员会，主要承担无线电监测和无线电频谱管理工作，Wi-Fi既然是一种无线技术，则需要在一定的规则下使用无线电资源。从全球来说，2022年，Wi-Fi的频段资源分为三个部分频段。① 2.4GHz频段，包括2.4～2.5GHz频段，100MHz带宽，适用于IEEE 802.11b/g/n/ax。② 5GHz频段，包括UNII-1（5.15～5.25GHz）、UNII-2a（5.25～5.35GHz）、UNII-2c（5.470～5.725GHz）、UNII-3（5.725～5.825GHz）等频段，适用于IEEE 802.11a/n/ac/ax。③ 6GHz频段，包括UNII-5、UNII-6、UNII-7、UNII-8（5.925～7.125GHz）等频段，1200MHz带宽。2020年4月，FCC开放了6GHz频段的频谱供未经许可者使用，这意味着Wi-Fi今后可以使用更多开放的无线电波来传输信号，新的商标为Wi-Fi6E，适用于IEEE 802.11ax。我国尚未确定是否把6GHz频段中的全部1200MHz带宽用于5G移动通信，也可能参照欧盟的标准，把部分频段留给Wi-Fi6E。所以目前来说，我国可用Wi-Fi频段是2.4G ISM频段和5G UMII频段（UNII-1,UNII-2a，UNII-3）,如下图所示。我国可用Wi-Fi频段但是这些频段也是无需授权使用的无线电资源频段，意味着民用的诸多无线电产品均可以使用这些频段。常见的蓝牙设备、微波炉、日光灯、摄像头等等都可能成为干扰Wi-Fi的因素，因此分析Wi-Fi干扰原因需要借助能够透视2.4G频段和5G频段的设备。常见引起Wi-Fi干扰的设备NetAlly EtherScope nXG 300C作为一台便携手持式测试工具配合NXT-1000频谱分析卡，可以全面了解射频情况及其评估干扰对无线网络的影响。Etherscope nXG 300c网络测试仪和NXT-1000频谱卡它可以支持通过提供 2.4GHz 和 5.0GHz 频段的可见性来简化干扰故障排除定位在射频环境中运行的任何 Wi-Fi 或非 Wi-Fi 干扰源便于观察 Wi-Fi 干扰活动特征，减少定位和修复无线网络问题的时间定位恶意的射频干扰源（如射频干扰器）来保护 Wi-Fi 网络获得直观的诊断视图频率频谱 -跨频段的频谱( 热图) 显示瀑布图-RF的瀑布图显示( 2分钟历史)实时FFT-实时显示当前、平均和最大保持信号强度...

NetAlly AirCheck G3 PRO有线网络测试的说明

2023/05/25

BACKGROUNDSome of our customers have commented on the lack of an Ethernet test port on the AirCheck G3. While a useful feature, the decision to leave that capability off AirCheck G3 was driven by the following factors:• The Ethernet test port was left off for space (both board space and package size), power, cost, and cooling reasons.• The elimination of the Ethernet port is what has allowed us to create a Wi-Fi analyzer with 10 hours of use time – feedback from our beta customers and others about the trade-off (“Would you rather have 10 hours of usage or 3-4 hours with Ethernet testing?” invariably, the answer is, “Yes, please give us more testing time.”• We choose to go with the 2nd Wi-Fi radio as the management port since this is a Wi-Fi tester and the convenience of the Wi-Fi connected management plane allows scanning while uploading data or when using remote control. Our focus is on complete mobile operation.SOLUTIONWhile most AirCheck G2 users operate in installed Wi-Fi environments and are not using/testing wired connections, we recognize that at certain project phases or in confirming network configuration, testing AP uplinks is still a necessary function. We also recognize that any change in functionality between product generations (e.g., the EtherScope nXG does not do inline testing compared to its predecessor, the OneTouch G2) will affect some users, we have identified 3 solutions:1. For the case of uploading test data at sites without any Wi-Fi or hotspot, the current G3 supports any USB (Type A) Ethernet adapter. These are quite popular (dozens for $15 USD, even the Amazon Basics brand) because newer laptops also do not support wired Ethernet, nor do tablets/gaming stations. In addition to providing a wired management plane for pushing results to Link-Live or for remote operation, this also provides ‘basic’ connectivity testing as you will see Link/Traffic LEDs on the adapter and the G3 will show the wired IP address – see image below. (In many cases, the IP address provides the user an indication of what VLAN the port is a member of.)2. In our December v2.2 release for AirCheck G3, we added the ability to ‘pair’ a LinkSprinter® or Test Accessory to an AirCheck G3 via Link-Live. Anytime a wired test is run from the paired tester (on a link with connectivity to Link-Live), the results will be automatically pushed from Link-Live back to the AirCheck where they will be displayed – think of it as a display on the LinkSprinter or Test Accessory when the LEDs do not provide enough information.3. We have identified a new 2.5GBASE-T USB Ethernet dongle that we are investigating for future support of testing newer 6/6E wired AP connections.See below for example of Ethernet link IP address when using a USB adapter:Below, see configuration of Link-Live for pairing LinkSprinter or Test Accessory to an AirCheck G3. Test results are pushed to the tester from Link-Live and can be seen in the Android notifications drop-down....
