Useful tips and tricks for your first measurement experience
Resistors, capacitors and inductors are the most basic components in electric circuits. It must be ensured that they work properly and accurately. Therefore, they need to be tested thoroughly during circuit design. This is usually done using LCR meters, which have become indispensable in the lab and in production. This application note looks at how to perform basic capacitor and inductor measurements accurately and reliably.

This paper describes the measurement of additive/residual phase noise of power amplifiers or multipliers for example for automotive RADAR sensors at 80 GHz using the interferometric measurement approach in combination with a phase noise and VCO tester R&S FSWP. The setup provides a way to characterize the additive/residual phase noise of amplifiers down to -150 dBc/Hz at 100 kHz offset even in the microwave range at 80 GHz.

A measurement campaign quantifying the impact of intermodulation in 5G TDD networks
Critical infrastructure: With the deployment of TDD networks, the mobile network community recognizes the critical importance of cell synchronization and the use of uniform TDD patterns across different networks for the proper operation of mobile radio networks. Variety of scenarios: Possible scenarios include cross-border situations, interactions between private campus networks and public mobile networks, and accidental synchronization chain breaks or misconfigurations within the mobile network.Measurement techniques: To quantify the effects of non-synchronized cells and using different TDD pattern in neighboring networks, R&S, in collaboration with TU Dresden and Advancing Individual Networks GmbH (AIN), conducted a measurement campaign using movable networks with full control over all network parameters. This campaign measured the effects on uplink and downlink throughput, mapping these to RSSI/RSRP values received at the interfered site.Customer benefits: The available quantification is valuable for predicting and assessing potential interference scenarios before setting up and operating a new cell site.

Performing precompliance measurements on power supplies requires using a line impedance stabilization network (LISN) for results that can be compared to limit values. While LISNs are standard in any precompliance lab, often no LISN is available for early R&D testing. If high accuracy is not your goal and you just need a simple tool for debugging, you can build your own LISN. Rohde & Schwarz oscilloscopes with powerful FFT analysis, are ideal for optimizing EMI filters or debugging unwanted emissions during development.

Unattended observation of spectrum occupancy for finding spurious emissions or seldom-occuring interferers is a common task for spectrum analyzers. Sometimes spectrum data has to be monitored over quite a long period of time. TraceRecorder, a small, free-of-charge software tool for storing measurement data from Rohde & Schwarz spectrum analyzers helps you to perform this measurement task. Running on a PC, it connects to the spectrum analyzer via a LAN interface. For stand alone operation, it is possible to run it directly on a spectrum analyzer, eliminating the need for an additonal computer during data acquisition.

Best practices for mobile network testing for business-critical applications
Business-critical infrastructure: Industrial applications require extremely high reliability and availability, as any downtime can result in significant financial losses. Fundamental requirements: Industrial applications often require low latency and even more important a sustainable latency to ensure real-time communication and control. Measurement Techniques: As soon as the radio access network is used, innovative testing methods are needed beforehand to proactively test the network capability and to identify any potential issues. We propose a standard test procedure for the characterization of a network regarding industrial use-cases that covers a representative set of different, common types of network traffic.

A programmable data generator such as the combination of SME with option SME-B11 is a novelty with signal generators. To make it easy for the user to get acquainted with the option and to ensure efficient operation, possible applications are described below. The data generator is used for producing binary data as well as control signals for level switching whenever digitally modulated signals are used. For a start we should like to deal in brief with the various settings available for digital modulation. Taking GSM as an example, the programming of data lists will be described next. The description for GSM can be easily applied to other digital networks as well. Next the generation of level bursts and the extension of data generator memory with option SME-B12 are described. The last section deals with special subjects such as FSK using data rates below 400 bits/s and pulse-amplitude modulation. A basic knowledge on digital modulation and TDMA will be sufficient to follow the topics.

Automotive radars are essential to safety systems such as collision avoidance and adaptive cruise control. The radars are a pillar of ADAS/AD systems and an important part of sensor fusion. The effective isotropic radiated power (EIRP) of automotive radar sensors is the total power emitted from radar antennas and a comprehensive measure of signal strength and coverage capability (essential to assessing automotive radar sensor performance). The AREG800A automotive radar echo generator makes for easy EIRP measurements when validating automotive radar sensors.

Battery life time is usually one of the most important specifications for battery-powered devices. Depending on the application, life time requirements can range from tens of hours for typical wearables like smart watches to ten years for smart sensors. Understanding where and when energy is used in order to minimize power consumption is therefore key for any of these devices.The power consumption analysis tool was developed to make it easier for customers to analyze power consumption data collected with either the NGL, NGM or NGU power supplies from Rohde & Schwarz. It allows to easily capture power consumption data and analyze using basic measurements.
