  • 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.

  • Fast download of waveform data with the R&S®RTO oscilloscope

    Overview of the choices for downloading waveform data for remote processing

  • 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.

  • Testing airborne radios to the limits

    Replace extensive field tests on fast frequency hopping radios by simulating real-world radio link conditions in the lab

  • Analyzing common mode noise of EPS for flawless touchscreen operation

    Modern, capacitive touchscreens as used, for example, in mobile phones are susceptible to common mode noise exhibited by external power supplies (EPS).

  • Capturing small ECG signals in medical applications

    Capturing small ECG signals in medical applications Capturing small ECG signals in medical applications Capturing small ECG signals in medical applications Your task An electrocardiogram (ECG) is widely used in medicine to monitor small electrical changes on the skin of a patient’s body arising from the activities of the human heart. This simple and noninvasive measurement easily indicates a variety

  • IoT Power Consumption Measurement

    IoT devices have tight requirements for power consumption in order to achieve expected battery life times of multiple years without a connection to a power supply. In order to verify the power consumption and expected battery life time, voltage and current have to be measured accurately for different operating states of the device under test.This application note explains battery life tests using RT-ZVC in combination with CMWrun and CMW500, including example applications.The solution by Rohde & Schwarz enables precise voltage, current and consequently, power measurements.The RT-ZVC Multi-Channel Power Probe can be driven as part of a test plan combining signaling and power measurements for a detailed view of the power consumption in different signaling states as well as an estimation of overall lifetime given a certain battery capacity.
