antenna array testing - conducted and over the air: the way to 5g m. kottkamp, c. rowell 1ma286 5g networks will need to offer more capacity and flexibility while lowering the operational expenses of the system. two new technologies can simultaneously address both the increase in capacity and the increase in energy efficiency: virtualization & massive mimo. this white paper provides an overview of
interchangeable port connector system, test port adapter system 1ma100 a test port adapter system is implemented for all rohde & schwarz equipment, which operates above 26 ghz in order to protect the rf front-end from mechanical damage. the test port adapter system consists of an rf front-end interface called the test port adapter body, and the test port adapter head which is attached to the body.
rohde & schwarz drivers under vee - installation and troubleshooting 1ma035 the use of rohde & schwarz device drivers under vee software is not complicated. however, a number of factors are involved, the errors that occur are often difficult to diagnose. this application provides easy and detailed support for installation and troubleshooting using national instruments or agilent gpib boards. instrument
group delay and phase measurement on frequency converters 1ez60 frequency converters e.g. in satellite transponders need to be characterized not only in terms of amplitude transmission but also in terms of phase transmission or group delay, especially with the transition to digital modulation schemes. they often do not provide access to the internal local oscillators this application note describes

gde test sequencer 1ma83 gde (= generic demonstration engine) is a easy-to-use, free-of-charge remote control command sequencer tool. the big advantage is that the test description is stored in a simple, easy-to-read text file, and loaded in gde at runtime. this makes it very easy to modify tests by the user or add additional tests to already existing test solutions without redistributing big setup
using matlab for remote control and data capture with r&s spectrum and network analyzers 1ef46 spectrum and network analyzers are capable of measuring large amounts of data that require complex mathematical processing; matlab is a powerful tool for such operations. this application note describes how instruments can be controlled directly from matlab scripts and how measurement data can be imported

使用 r&s®zvr 矢量网络分析仪的时域测量 1ez44 zvr 系列的矢量网络分析仪可测量频域内被测设备 (dut) 的复杂 s 参数的幅度和相位。 使用反傅里叶变换，可将相关结果变换为时域， 由此获得 dut 的脉冲或阶跃响应，以便极为清晰地表现设备特性。 比如，用户可以直接定位电缆故障。 此外，特殊的时域滤波器（即门限）可用于抑制干扰信号分量，比如多重反射。 zvr,zvc,zvre,zvce,zvm,zvk,时域,微波 使用 zvr 矢量网络分析仪的时域测量
通过 dde 存取测量数据并控制矢量网络分析仪 1ez33 rsib 接口便于通过 dde 使用 windows 应用程序控制 zvr 系列的网络分析仪。dll rsib.dll 中已经列入了接口功能。 另一个 dll rsdde.dll 中描述了通过 dde 访问仪器固件的功能。 这些功能根据 rsib.dll 使用。 这些功能接口在很大程度上对应于 national instruments 针对 gpib 编程使用的接口。 功能名称与 ni 库中的名称相似，但前面加上 rsdll。 两个 dll 是固件的一部分，并且使用固件更新套件更新。 zvr,zvre,网络分析仪 通过 dde 存取测量数据并控制矢量网络分析仪
