An offline AC/DC switching converter has no separate bias power supply that provides power to the control integrated circuit itself. Here, an auxiliary primary winding and discrete components are added to supply power to the control circuit. Verifying this circuitry is essential and requires accurate and detailed signal level and timing measurements. The startup sequence takes a long time, which needs to be taken into consideration in the measurement and requires an instrument with sufficient memory.

This paper describes the characterization of aluminum electrolytic capacitors specifically used in AC-DC power converter applications. It will be discussed why this capacitor technology is critical regarding lifetime and why it cannot be substituted simply by any another capacitor technology. Different aging effects of the capacitor will be discussed. Usage of the capacitor in different AC-DC converter topologies will be presented. Simulation circuits will be used to analyze the capacitor in more detail before suitable measurements will be performed to demonstrate a real example of a switching-mode power supply (SMPS).After the introduction into the aluminum electrolytic capacitor basics and theory, this paper will also present all important and possible measurements of capacitor parameters, like capacitance, equivalent series resistance (ESR) and ripple current. This includes in-circuit measurement which can be performed with an oscilloscope. An LCR-bridge is used to obtain high accuracy measurements in addition. A comparison between the two measurement methods will be presented. Furthermore, the required measurement hardware for the in-circuit measurements and the bridge measurement will be discussed and presented.Lastly, two different lifetime calculation methods are presented and a real example is used to compare the advantages and disadvantages of the different methods.Thanks to Mr. Frank Puhane from Würth eiSos GmbH & Co. KG who provided me with all aluminum electrolytic capacitor samples including the prepared capacitor with build-in temperature sensors to perform all measurements. Furthermore, his great expertise was very beneficial and helpful to create this premium application note.

RF Level Measurement Uncertainties with the Measuring Receiver R&S FSMR
28-Mar-2006 | AN-No. 1MA92
For measurement settings below 10 mV/div, oscilloscopes typically reduce the measurement bandwidth in order to keep the trace noise as low as possible. The R&S®RTO is different: It offers the full bandwidth even for the most sensitive settings, and an A/D converter with more than 7 effective bits (ENOB) digitizes the signal.

Solutions and Tipps for NR FR1 in TDD Downlink Mode
5G New Radio (NR) is a radio technology specified by 3GPP and was first released in 3GPP release 15. It is designed to target three use cases, i.e. enhanced mobile broadband (eMBB), massive machine type communication (mMTC) and ultra-reliable low latency communication (URLLC). Among these three use cases, eMBB represents actually a further evolution of mobile broadband communication from LTE standard. According to the technical performance requirement defined by IMT-2020, by deploying 5G technology, peak data rates of eMBB application are expected to reach 20 Gbps in downlink (DL) and 10 Gbps in uplink (UL) direction, respectively. Typical use cases of eMBB are data hungry applications, such as high resolution 8K video streaming, virtual reality (VR), augmented reality (AR) etc.Verification of a 5G capable user equipment (UE) with respect to its achievable maximum data throughput under controllable and deterministic test conditions is an essential process during the design phase of the product. Performance centric verification through identification of the data throughput bottleneck, product benchmarking against a golden device enhances tremendously the user experience in the end.This document focuses on 5G NR frequency range 1 (FR1) with TDD duplex mode in E-UTRAN New-radio Dual Connectivity (ENDC) operating mode. As 5G NR physical layer offers a plethora of flexibility, the motivation here is to provide a kind of guideline of relevant parameter settings to stimulate device under test (DUT)'s max throughput capacity. The status quo of the R&S solutions at the time when the application note is created are described. Shown feature sets are constantly evolving, so the screenshots used and the parameters shown may change.
