Analyzing high speed datacom interfaces is an important task and ensures signal integrity. One major challenge of this analysis is the connection between the physical interface and the oscilloscope, as most of the datacom interfaces do not provide test connections suitable for RF. A test fixture is required as a bridge between the high speed datacom IF and the RF connector of the oscilloscope, but this will affect the signal integrity measurement. The R&S®RTP and R&S®RTO oscilloscopes with the advanced jitter option can analyze and separate jitter contributions. Additionally, the option can evaluate the impact of test fixtures and traces inherently and give the user a good understanding of the impact of their test setup.

Automated test equipment (ATE) is a cornerstone in production facilities. Devices under test (DUT) have to be measured according to various limits to ensure safe and reliable operation for the user. A production facility must ensure that these tests are performed properly and cover all the necessary test cases. However, the tests must also be executed with sufficient speed. Oscilloscopes (e.g. the MXO series from Rohde & Schwarz) are often a typical part of ATE and can improve the workflow with a dedicated “waiting for trigger” signal.

Automotive radar sensors concealed in bumpers must transmit in the correct frequency domain. To effectively hide sensors, radar-transparent areas usually have the exact same paint as the rest of the vehicle. When selecting paint and coatings for bumpers, you need to know their material properties. In the past, either quasi-optical or waveguide based setups with vector network analyzers (VNA) were used. The following application card describes a simplified material characterization method in the automotive radar frequency domain (76 GHz to 81 GHz) with the R&S®QAR50 automotive radome tester.

Today’s complex circuits must integrate several components that feed on different power levels. A robust circuit that ensures interoperability of these components needs carefully designed, clean and stable power distribution networks for power timing. At lower voltage levels, tolerance is defined in percentages and can make precise measurements challenging.

Spectrum clearance in mobile networks is becoming ever more important as operators use new bands that previously contained other services. This is particularly important for the 5G NR rollout. 5G NR has already initiated a worldwide deployment of TDD networks in an unknown radio environment where unwanted transmitters can create uplink interference masked by downlink signals, making interference hunting particularly demanding. Automated detection of interference signals before a network switches on can be a big help in addition to traditional manual techniques.
