Voice Call Aspects in 5G New Radio Networks

Functional Testing

Although data services in the context of eMBB, URLLC and mMTC are the pivotal drivers behind the 5G evolution, legacy services like voice and video communications still represent important services that operators want to offer to their subscribers. As part of the technology evolution, we have seen a major change from circuit-switched 2G networks with an initial focus on telephony to fully packet-switched 4G networks focused on internet data communications.This application note focuses on different details of voice services in 5G networks. Besides some theoretical background this document describes the procedure to setup a 5G network with R&S®CMW500 and R&S®CMX500 radio communication testers and how to carry out different functional voice call tests for 5G networks.

External Sweep and Adaptive Measurement of DUTs with extreme Transients using the Settling Function of the Audio Analyzers UPL and UPD

When measuring audio components with unknown transients, the experienced engineer watches the settling of the DUT before accepting a measured result to be valid. The settling function in the UPL/UPD simulates this process and automates it by continuously comparing the measured value with a number of measured values stored before. A measured value is only accepted as being valid if it is within the tolerance limits entered by the user. This application note explains the settling process and gives hints for practical use.

Output Power Measurement on Noise Sources

Noise sources used for noise figure and gain measurements are typically controlled by the spectrum analyzer or noise figure meter instruments and are calibrated with their ENR value (Excess noise ratio). While this external control and the use of ENR values is common in noise figure test, it may be difficult in system applications where the noise source control is not available, and the use of ENR values is replaced with the values for the noise output power of the noise source. The calculation of the output power for the noise source requires to know the P_hot value (hot power) which is not a common specification for noise sources used in test and measurement applications.This application note describes a technique to perform a calibrated noise power measurement (P_hot) with spectrum analyzers and noise sources. The next sections will give further details.

Path Compensation for MS Fading Tests

As well as static tests, modern mobile communication standards also stipulate measurements under fading conditions, sometimes with additional white gaussian noise AWGN. Rohde & Schwarz supports these tests with the combination of the R&S®CMU200 Radio Communication Tester and the R&S®SMU200A or R&S®AMU200A Vector / Baseband Signal Generator and Fading Simulator. Applying fading and noise always raises the crest factor of a signal considerably. Thus, automatic path attenuation inside the Rohde & Schwarz baseband fader prevents the new signal peaks from being clipped at I/Q full scale. Any additional attenuation in the baseband, however, makes the RF output fall below its intended level. This application note shows how to achieve an accurate RF output level by compensating for the I/Q attenuation - without modifying the test setup or using additional instruments.

UWB EMISSION MEASUREMENTS WITH SPECTRUM ANALYZERS

The verification of emissions according to EN or FCC standards is mandatory to avoid any interference with existing users. Besides the common emission tests with measurement bandwidth up to 1 MHz and mean power measurements, most regulations also require to test peak transmission power within a 50 MHz bandwidth to avoid interference with any existing wideband applications, for example radar receivers. This application note provides information how to perform spectral emission measurements on UWB signals with spectrum analyzers using wide bandwidth RBW filters, and explains the capabilities and the limiting factors of the Rohde & Schwarz FSW signal and spectrum analyzer to perform this measurement. The next sections will give further details.
