  • Measuring RDS(on) with high-definition oscilloscopes

    RDS(on) of MOSFETs is a key parameter for determining the conduction loss in switched-mode power supply applications and is therefore of special interest. When a switching MOSFET is off, it has a high drain-to-source voltage, but when it is turned on the voltage drops to just a few hundred millivolts. A high-resolution oscilloscope is needed to measure these low voltages. Probe compensation and correct probing are also vital for accurate RDS(on) measurements.

  • Methods to obtain trusted RMS results on the R&S®RTM

    RMS is one of the most common parameters in test and measurement. Mathematically, it is the quadratic mean of continuously varying values (waveform). Especially when quantifying power, RMS simplifies the calculation as the polarity of the voltage and direction of the current can be disregarded.

  • Quick and efficient troubleshooting with the R&S®Scope Rider

    Signal faults and anomalies can cause electrical and electronic systems to fail. Especially in the field, these errors can lead to system downtimes and produce high costs. Consequently, finding them quickly and efficiently as well as identifying their source are crucial.

  • Faster debugging using specialized triggers

    In addition to the generic edge trigger, modern oscilloscopes offer triggers that are specialized to address specific problems.

  • Comparison of jitter measurements in the time and frequency domain

    When analyzing the robustness of data transmission systems, jitter is a key indicator. It is recommended to use jitter measurement instruments for both the time and frequency domain in order to differentiate between fast and slow moving artifacts.

  • Dynamic re-referencing – microvolt-level measurements with the R&S®RTO oscilloscopes

    In order to clearly visualize and make repeatable measurements on signals with amplitudes of less than 1/100 of a division, and stabilize signals captured over very long periods, the R&S®RTO oscilloscope’s powerful combination of measurement and math channel capabilities allows corrective offset adjustments on individual acquisitions more than one hundred times per second.

  • Benefits of R&S®RTO digital trigger system

    The trigger is a key element of an oscilloscope. It captures specific signal events for detailed analysis and provides a stable view on repeating waveforms. Since its invention in the 1940s the oscilloscope trigger has experienced continuous enhancements. The fully digital trigger of the R&S®RTO digital oscilloscopes sets an innovation milestone that brings significant advantages for the oscilloscope user in terms of measurement accuracy, acquisition density, and functionality. This application note introduces the working principles of a conventional trigger system and explains the advantages of the real-time capable digital trigger of the RTO oscilloscopes.

  • Advanced Signal Analysis using the History Mode of the R&S®RTO Oscilloscope

    Rare faults and intermittent signals are difficult to capture. The R&S®RTO Oscilloscope supports the acquisition and the detailed signal analysis of these signals by using the history mode. The history mode allows the user to look back to previous acquisitions and apply the wide set of analysis functions of the RTO. Furthermore it stores the accurate recoding time of the waveforms for subsequent analysis.

  • Jitter Analysis with the R&S®RTO Digital Oscilloscope

    This application note presents the Jitter analysis capabilities of the R&S®RTO for digital signals. It demonstrates the basic operation with an application example, and shows the associated jitter analysis.

  • Measuring with oscilloscopes

    This educational note covers the theory and practice oscilloscopes based on concrete measurement examples that address authentic everyday tasks.The theoretical portion of this paper begins with an explanation of the basic operating concepts for oscilloscopes, followed by a discussion of the most important parameters to be considered when setting up and performing the exercise measurements.The practical portion of the educational note contains detailed measurement tasks that can be performed by small groups in the university lab. These exercises are intended to demonstrate and reinforce the knowledge gained in the theoretical portion. The exercises build upon one another and demonstrate measurement tasks that are frequently encountered by engineers in daily work.
