TDMA communications systems like GSM, DCS 1800 or PCS 1900 make effective use of the frequency spectrum by assigning several subscribers to the same frequency channel. Each subscriber has access to one predefined time slot for transmitting information. With GSM eight subscribers share one frequency channel with a bandwidth of 200 kHz. In order not to disturb the other users of the 200-kHz channel it has to be ensured that, for instance, a mobile sends in the assigned time slot only and that no power is emitted by the transmitter at other times. For this reason the transmitter power is practically switched off in the transmission intervals.

The R&S®SGT100A SGMA vector RF source offers a remote emulation feature that makes it possible to control the instrument by commands other than the built-in native SCPI commands. This feature allows the user to replace signal generators, e.g. from other manufacturers, with the R&S®SGT100A without having to change the remote control code. This application note describes how to use the remote emulation feature in general. Furthermore, it describes in detail the remote emulation for each supported instrument, limitations of the individual emulations and the remaining differences between the emulated and the original commands.

Distortions caused by components in the RFFE (radio frequency front end) limit the performance and throughput of communications systems. Types of distortions include:▪ AM-AM and AM-PM (complex variations of gain with amplitude)▪ Non-linear frequency response (memory effect)All RFFE components exhibit all of these distortions, only the proportions vary. In this Application Note, illustrative measurements of individual RFFE components, as well as a complete RFFE, will be made. This is followed by the documentation of a more complete analysis, including comparison against theoretical limits, of a linearized commercial SatCom BUC product.

Most of the tests specified in the standard TIA-98 that a CDMA2000® mobile station has to fulfill can be performed by the Universal Radio Communication Tester R&S®CMU200 without further assistance. Other tests, however, require additional instruments, for instance for generating interfering signals. Some tests of the standard TIA-98 need features that a tester optimized for production cannot offer, for example high dynamic spectrum analysis up to 12.75 GHz. This Application Note shows how to perform these tests easily with the remote-control software CMUgo, using the R&S®CMU200 in combination with R&S®SMU, R&S®SMJ, R&S®SMIQ, or R&S®SML signal generators, and R&S®FSQ, R&S®FSU, R&S®FSP, or R&S®FSL spectrum analyzers. New test items and sequences will therefore be included in the CMUgo software v1.9.8 to remote-control the R&S®CMU200, as well as the signal generators and spectrum analyzers. They are presented in this Application Note.

Using a Vector Network Analyzer from the ZVR family, not only magnitude and phase can be measured, but also group delay and even phase delay. Whereas phase delay measurements produce the highest accuracy for the electrical length of non-dispersive devices under test, such as coaxial cables, group delay measurements also give a detailed insight into the frequency dependent delay characteristics of dispersive devices, such as filters. In addition to the traditional step aperture technique, Vector Network Analyzers from the ZVR family offer a frequency aperture technique, which allows a well defined and constant aperture for group delay measurements also for a nonlinear frequency sweep.

This application note explains how to bring a CADENCE system which is attached to an R&S EX-IQ-BOX into service for the first time. The first part of the document shows how to setup an LTE Demo without using a UE design. This setup uses the R&S CMW500 as the downlink transmitter. The emulator receives the downlink via an R&S EX-IQBOX and passes it to an R&S spectrum analyzer (R&S FSx) via a second R&S EXIQ-BOX. The second part describes the real wiring using up- and downlink. This will only work if a UE design is available on the emulator.
