Since the video signal - composite or component - is a most complex one regarding the spectral density or even the group delay in the baseband, you need special procedures to measure the signal parameters with an objective and absolute accuracy of less than one percent over the whole frequency range up to 6 MHz. The following describes a method allowing the precise measurement of a baseband signal, which then may be taken for the calibration of video analyzers such as the well-known R&S units UAF or UVF and future products.

Modern societies worldwide depend on the performance, reliability and security of critical infrastructures and networks. There is a plethora of “new verticals” such as manufacturing, warehouse, mining, ports or other critical infrastructure, just to name a few. These “new vertical” use cases all have one common requirement: the mobile network needs to provide a superior performance compared to a commercial mobile network. In such environments 5G brings new capabilities to build fast and secure campus or private networks tuned to higher performance, which can increase productivity and efficiency. To be successful in these business-critical use cases, the wireless networks need to be as reliable as the wired ones. This educational note describes the different test methods to be able to verify the superior network performance and to help finding root causes of potential problems limiting the performance. We distinguish between passive tests and active tests.

Noise-Power-Ratio (NPR) measurements are a common procedure and a simple but useful tool to characterize the performance of power amplifiers for satellites or other multi-channel communication systems. The main advantage is the use of wideband signals like noise, multi-carrier CW tones or I/Q modulated signals, which leads to a better simulation of the real environment. This application note provides information how to generate these signals with a vector signal generator and perform NPR measurements with spectrum analyzers. With the R&S®SMW200A vector signal generator any desired test signal can be created. The R&S®FSW spectrum and signal analyzer offers an automated function for NPR measurements. The limiting factors of both a vector signal generator and a spectrum analyzer are explained. Measurement examples show the practical results of NPR measurements.

Digital pre-distortion (DPD) is a common method to linearize the output signal of a power amplifier (PA), which is being operated in its non-linear operating range.Most PAs operate in their non-linear range for efficiency reasons. The drawback of higher efficiency is the non-linear operating range. In order to maintain signal quality, many transmitters employ DPD. Implementing real-time DPD in a transmitter is a challenging task and often ends in PA models, which are specific to the signal transmitted.Even though these complex models are required for transmitter development, they are not needed during PA verification and development.This article describes an approach to generate a pre-distorted signal based on a hard-clipper. The resulting waveform pushes the output of the DUT as close to the hard-clipper as possible.Due to the waveform approach, the algorithm compensates all memory effects.

Receiver diversity improves reception quality by using multiple antennas with a preferably low correlation factor between each receive path. The result is a much more robust reception, since a deep fade will not affect all received signals at the same time.However, the complex geometry and positioning constraints for antennas of the receiving devices can introduce an unwanted correlation between channels. The popular diversity test setup consisting of several independent transmitters does not serve the needs of a realistic simulation, because radio channel correlation is not simulated.This application note explains a compact and versatile MIMO test solution for any common broadcast standard with real time fading including the simulation of channel correlation for a 1x4 MIMO system.The test setup allows very precisely specified individual multipath profiles.
