Radar, satellite communications and 5G NR use AAS with phased array antennas for beamforming. Hybrid beamforming combines the flexibility of digital beamforming with the efficiency of analog beamforming.
Increasing integration enables compact and cost-efficient AAS. To achieve accurate, reliable and efficient beamforming,...

Vector Network Analyzers of Rohde&Schwarz family are able to measure magnitude and phase of complex S-parameters of a device under test (DUT) in the frequency domain. By means of the inverse Fourier transform the measurement results can be transformed to the time domain. Thus, the impulse or step response of the DUT...

In a design of a modern switch-mode power supplies (SMPS), the designer has to ensure that the converter is operating in its specified values over all circumstances. For example, some of these tests to ensure proper performance are output voltage deviation test, load transient test, output voltage ripple, input voltage...

Deembedding, often a necessary and complex task, is made easier with an integrated hardware and software solution. Whether you are debugging a high-speed interface such as DDR or PCIe, characterising a fast clock or analysing a complex RF signal, you want to see the real signal and not artifacts of the test setup such...

A real-time operating system (RTOS) must be fast and responsive, schedule tasks and manage limited resources, and ensure functions are isolated and free of interference from other functions.
In this report, you’ll learn more about what is a real-time OS and the pros and cons of two types of RTOS architectures:...

Medical device designers have become increasingly interested in the Linux ® operating system (OS), largely because of its open source model. Linux lets the designer leverage a large pool of developers, a rich legacy of source code, and industry-standard POSIX APIs.
But Linux may not be the right choice for all...

Vector Network Analysers (VNA) are gaining popularity in the Signal Integrity community as Time Domain Measurement and Analysis tools.
VNAs with 8 ports or more can provide significant decreases in test time by migrating from a 4-port measurement system to an 8-port measurement system. For tight tolerance DUTs...

One of the primary purposes of a gate driver is to enable power switches to turn on and off faster, improving rise and fall times. Faster switching enables higher efficiency and higher power density, reducing losses in the power stage associated with high slew rates. However, as slew rates increase, so do measurement and...
