During wireless transmission over the air a signal is subject to fading. Since fading can strongly influence the communication, devices such as mobile phones must be tested under real-world conditions to verify their performance. The Rohde & Schwarz vector signal generators R&S®SMW200A, R&S®SMU200A and R&S®AMU200A make it possible to perform such tests. Their integrated real-time fading simulators reproduce well-defined and repeatable real-world test scenarios to bring reality into your laboratory. A multitude of standard-compliant, preconfigured fading scenarios make the configuration as easy as possible.This application note gives a brief introduction to fading and explains how to use the fading simulators in custom applications.

The RSIB interface enables the network analyzers of the ZVR family to be controlled by means of Windows applications via DDE. The interface functions are contained in the DLL RSIB.DLL. The other DLL RSDDE.DLL provides functions for the DDE access to the instrument firmware. These functions are used by RSIB.DLL. The interface of these functions greatly corresponds to that of National Instruments for programming the GPIB. The function names are similar to those of the NI library but preceded by RSDLL. The two DLLs are part of the firmware and are updated with the firmware update kits.

The Society of Cable Telecommunications Engineers (SCTE) defined the ANSI/SCTE 40 specification: Digital Cable Network Interface Standard. ANSI/SCTE 40 tests are designed to test conformance of set-top boxes and other cable receiving equipment to ensure that they will operate correctly when installed in a cable system. The tests are a combination of noise (AWGN and phase noise), AM hum, micro-reflections, digital and analog adjacent channels, and other discrete interferences. These impairments are found on most cable systems to some degree. Rohde & Schwarz provides set-top box manufacturers with an easy solution to perform conformance testing in line with ANSI/SCTE 40 by using the R&S®SFU broadcast test system and the R&S®SFE100 broadcast tester. The R&S®SFU is able to perform most of the test procedures in one unit. Furthermore, additional test transmitters allow the simulation of full channel loading. This Application Note explains the specific test requirements, a possible setup, and the configuration using the R&S®SFU/SFE100.

Leaving aside the microwave generators, the present line of Rohde & Schwarz products comprisessignal generators up to 1 GHz (SMX, SMG), up to 2 GHz (SMH, SMGU), up to 3 GHz (SME, SMT) and up to 4.3 GHz (SMHU). For applications at higher frequencies, all signal generators can also be operated with an external passive frequency doubler. This extends the range of possible applications up to 8.6 GHz. Some degraded specs regarding level and modulation are described below. For people using the frequency range 3 to 6 GHz, the low priced combination SMT plus frequency doubler will mainly be interesting. Signal generator SMHU is useful for the frequency range up to 8.6 GHz. Especially the phase noise performance is excellent with this instrument. the required output signal. It should also be pointed out that the residual FM and the SSB phase noise will be 6 dB poorer as a result of frequency doubling.

Solutions and Tipps for NR FR1 in TDD Downlink Mode
5G New Radio (NR) is a radio technology specified by 3GPP and was first released in 3GPP release 15. It is designed to target three use cases, i.e. enhanced mobile broadband (eMBB), massive machine type communication (mMTC) and ultra-reliable low latency communication (URLLC). Among these three use cases, eMBB represents actually a further evolution of mobile broadband communication from LTE standard. According to the technical performance requirement defined by IMT-2020, by deploying 5G technology, peak data rates of eMBB application are expected to reach 20 Gbps in downlink (DL) and 10 Gbps in uplink (UL) direction, respectively. Typical use cases of eMBB are data hungry applications, such as high resolution 8K video streaming, virtual reality (VR), augmented reality (AR) etc.Verification of a 5G capable user equipment (UE) with respect to its achievable maximum data throughput under controllable and deterministic test conditions is an essential process during the design phase of the product. Performance centric verification through identification of the data throughput bottleneck, product benchmarking against a golden device enhances tremendously the user experience in the end.This document focuses on 5G NR frequency range 1 (FR1) with TDD duplex mode in E-UTRAN New-radio Dual Connectivity (ENDC) operating mode. As 5G NR physical layer offers a plethora of flexibility, the motivation here is to provide a kind of guideline of relevant parameter settings to stimulate device under test (DUT)'s max throughput capacity. The status quo of the R&S solutions at the time when the application note is created are described. Shown feature sets are constantly evolving, so the screenshots used and the parameters shown may change.

In modern telephoning, dual-tone dialling is used more and more often. Every symbol to be transmitted is coded by two frequencies which are sent at the same time. To ensure a trouble-free call setup, transmission has to be done within defined tolerances. For measuring these kind of dialling signals, the measurement equipment has to fulfill high requirements. This application note describes how the measurements can be carried out by using the Audio Analyzers UPL or UPD. It also presents a measuring program for this application.
