This document is divided in two parts and starts with an introduction in AC-DC conversion principles in general. It will present the most common circuits used for different power levels. The switching mode power supply (SMPS) converter will be the main focus as they are used everywhere in the electronics. Especially the flyback converter design in different flavors are highlighted. Nevertheless, all measurements are also applicable for other SMPS converter designs operating at higher power levels.In the second part of this document, most relevant testing methods and procedures of an AC-DC converter are highlighted. For each testing section, a fundamental part will be upfront discussed and it is followed by a presentation of a suitable measurement method. In this second part, the device under test (DUT) is considered as black box device and thus the structure is similar. Therefore, the testing parts consists of methods related to input tests, output tests and a combination of both like efficiency. Of course, some test performed at the output of the converter are also relevant for DC-DC converter, e.g. the validation of the output ripple.

Radar equipment is always designed to work at the technologically feasible limits. Therefore the true performance of radar equipment can only be measured with the most accurate and reliable pulsed test signals. The R&S®SMA100B analog RF and microwave signal generator with its high-quality pulse modulator provides narrow pulse modulation. Thanks to a powerful closed-loop level control concept also for narrow pulses, outstanding level accuracy and repeatability is now available for pulse widths starting at 100 ns.

Keeping an ATSC (or ATSC Mobile DTV) single-frequency network (SFN) running smoothly not only requires that every single TV transmitter functions properly – the RF performance criteria echo pattern and frequency deviation also have to be strictly complied with. The R&S®ETL TV analyzer enables operators to check these crucial RF parameters at a glance with unmatched precision. The patented implementation achieves an echo delay resolution of one nanosecond, which is nearly a hundred times higher than in conventional approaches. This allows more precise control and adjustments of the several transmitters within the ATSC (or ATSC Mobile DTV) SFN and thus helps to ensure excellent coverage for the receivers.

PAM-4 (4-level pulse amplitude modulation) has been introduced in high-speed serial data technology to reduce the bandwidth demands of ultra-high data rates. It uses only half the bandwidth per bit that would be required of conventional NRZ (non-return to zero) modulation. But at the same time, PAM-4 signaling complicates design and test at every turn. Evaluation of channels is now just as important to system development as serializer / deserializer (SerDes) testing and the challenges presented require a higher level of test and measurement performance than ever before. This paper investigates the evaluation complexities of PAM-4 interconnects at high data rates.

This application note introduces the reader to the SpaceX Hyperloop Pod Competition project and their special demands for the electrical drive train. Common motor technology like brushless motors and their typical control methods widely used in the industry are also discussed within this document.However, the main focus of this paper is a demonstration of a power measurement method of a three-phase inverter by means of a 4-channel oscilloscope. Not only the theory of the power measurement is presented but also the conducted measurement is presented including tips and tricks to obtain the best measurement results.The measurement solution provided by Rohde & Schwarz was mandatory for the TUM Hyperloop team to overcome challenges in optimization of the electrical drive train used in the SpaceX Hyperloop Pod Competition project.Many thanks to Mr. Johannes Ungar and Faruk Centinkaya (TUM Hyperloop) for contributing significantly to this application note. By combining their expertise in electrical drive trains used in the Hyperloop Project and with a Test & Measurement solution from Rohde & Schwarz, we have achieved synergies that will be beneficial for any design and test engineers in the industry.

DVB-T signal quality is determined by measuring the modulation error ratio (MER). However, a poor MER does not indicate its causes since different interference factors overlap at the transmitter when a signal is generated and transmitted. The R&S®ETL TV test receiver now has a unique new measurement capability that makes it possible to demonstrate to what extent the modulator's phase noise affects the MER.

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.
