A new phase noise test instrument covers the frequency range from 1 MHz to 50 GHz with direct down-conversion analog I/Q mixers and baseband signal sampling. The traditional PLL has been replaced by a digital FM demodulator for phase detection and frequency tracking. An additional AM demodulator enables concurrent measurement of phase and amplitude noise. The instrument can measure phase noise as low as -183 dBc/Hz with a 100 MHz carrier frequency and 10 kHz offset within two minutes.

Measurements of very high noise figure components are performed for a number of reasons. For instance, in a wide range of applications, devices under test (DUT) are characterized within a complex test setup that includes high losses before or after the low noise DUT. In case of high frequencies, the switch matrix with complex signal routing and cables might have a very high loss. In other cases, the device might be embedded in a test setup where direct access is physically impossible, on-wafer probing is one example for this case. Using conventional measurement equipment, the noise figure measurement of such a device is very unstable if not impossible at all.

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.

Reflection measurements are a common way of assessing antenna system performance. When a minimum amount of the transmitted signal is reflected, it indicates that the transmission energy can reach the intended coverage. Undesired high reflection causes the system to be inefficient and can damage components. Reflection measurements can be expressed in terms of return loss, VSWR and reflection coefficient.

Most of the tests specified in standard TS 34.121 that 3GPP WCDMA user equipment (UE) has to fulfill can be performed solely by the Universal Radio Communication Tester CMU200 universal radio communication tester. Other tests, however, require additional instruments for generating one or more interfering signals, for fading setup or for high dynamic spectrum analysis. This application note shows how easy it is to perform these tests with the remote-control software CMUgo, using the CMU200 in combination with R&S signal generators and R&S spectrum analyzers.

Signal Generation and Analysis

This Application Note supplements the video series, describing signal generation and signal analysis for Dynamic Spectrum Sharing (DSS) for LTE and 5G NR. The video series is located below this paragraph.In this illustration, a four frame (40 subframes) long LTE sequence will be created, and exemplary MBSFN slots inserted, carrying 5G payloads. That signal sequence will be compiled and played by the SMW signal generator. The FSW signal analyzer LTE and 5G NR personalities are then used to analyze and verify the content of each subframe/slot.Three methods are presented, (1) Manual Entry using the GUI, (2) SCPI command sequence/remote control and (3) configuration file. The latter variants require the download of various files, available at the bottom.The configuration file approach offers the fastest time to initially setup. The SCPI command sequences provides some insight of the functionality and settings at each step, and the supplied MATLAB® script (only core license required) provides a prototype to illustrate the programming of successive slots or subframes. The Manual Entry approach, using the instrument's front panel GUI, provides a step-by-step set-up instruction, which can itself be augmented with SCPI recording, for easy modification and programming.MATLAB® is a registered trademark of The Mathworks, Inc.

R&S®Server-Based Testing helps reduce test times for workloads that can be parallelized. 5G New Radio (5G NR) multicarrier signals are an ideal workload because each component carrier can be analyzed independently and in parallel. In an example EVM measurement, scenario test times are reduced significantly even when receiving I/Q data from just a single instrument.

Many measurements in audio applications have to be monitored for compliance with specified limit values. Therefore, sometimes a whole series of measurements have to be compared with a fixed limit value, in other case it might be necessary to define different tolerances for example for different frequency ranges. Both can be done using Audio Analyzer UPD or UPL. This application note covers the different possibilities of limit checking, it demonstrates how to edit limit files and presents a program to easily generate files for checking the limits of frequency response measurements. Furthermore the display modes for different kinds of references are explained.
