Verifying Power Integrity for DDR Memories

Accurate ripple and noise measurements on power rails require a high-bandwidth oscilloscope and a dedicated probe to perform low-noise measurements and provide the offset capability to zoom in on top of the DC voltage. The R&S®RT-ZPR20 power rail probe as well as the R&S®RTE and the R&S®RTO digital oscilloscopes are excellent tools for this measurements.

R&S RTO Oscilloscope Offers New Test Options for Fast Serial Interfaces up to 5 Gbit/s

Fast serial communications interfaces such as USB and PCIe have found their way into the designs of many electronic circuits. When testing and debugging circuits, developers need easy-to-use tools that provide comprehensive support for these interfaces. The most compact complete solution available today is offered by Rohde & Schwarz and consists of the following components: the R&S RTO2064 oscilloscope, the test options for the various interface standards, and modular R&S RT-ZM60 broadband probes for contacting the DUT. Rohde & Schwarz is expanding its offering with the following new test options: triggering and decoding software options for SuperSpeed USB (USB 3.1 Gen1), PCIe 1.1/2.0 and USB-PD, plus a compliance test option for PCIe 1.1/2.0.

Rohde & Schwarz Helps Developers Optimize Power Supplies in Wireless Devices

The new R&S RT-ZVC02/04 multichannel power probe can measure across large current and voltage ranges without having to switch ranges, making it possible to monitor the power consumption of chipsets, radio modules and wearables such as smartwatches. When used in combination with an R&S RTE or R&S RTO oscilloscope, the current drain can be clearly correlated with analog and digital control signals, enabling developers to optimize the battery life of such wearables and wireless devices early in the development cycle.

Fundamentals of Vector Network Analysis

One of the most common measuring tasks in RF and SI engineering involves analysis of circuits (networks). A network analyzer is an instrument that is designed to handle this job with great precision and efficiency. Circuits that can be analyzed using network analyzers range from simple devices such as filters and amplifiers to complex modules used in communications satellites.

New Probe for Rohde & Schwarz Oscilloscopes Measures Voltages in the Millivolt Range

The new R&S RT-ZP1X passive 1:1 probe from Rohde & Schwarz broadens the application range of its R&S RTO and R&S RTE series oscilloscopes. Both the probe and the oscilloscopes' front-end are extremely low noise, making this combination ideal for measuring the smallest of signals down to 1 mV/div, e.g., for power integrity measurements on integrated circuits and components.
