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...

Today, R&D engineers face challenging time-to-market goals. Extending the product development schedule and delaying the product launch can prove to be extremely costly in terms of opportunity cost and lost market share. Nearly 50 % of products fail EMC compliance the first time.
Every day spent on debugging, isolating...

This webinar introduces the Doherty amplifier as a special case of the “balanced” amplifier genre. We will discuss design & test challenges and show implementation variants that make it possible to increase output power and improve efficiency.
Using a dual input Doherty measurement setup as a reference,...

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...

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...

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...

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,...

Functional safety actively prevents the failure of a system from causing harm to people and property. Developers often need to certify a system as compliant with a functional safety standard.
In this report, you’ll learn about functional safety and explore functional safety terms, such as dependability and availability,...

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:...

Design and verification engineers will be learning the importance of ensuring a stable operation and of reducing the risk of failure after any change over the product’s lifetime. Both require a solid characterization of the memory interface.
We will be discussing test and tool requirements such as bandwidth,...

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...

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...

VDSL (very-high-speed digital subscriber line) technology is similar to the well-known ADSL, and facilitates the delivery of information at speeds of up to 52 Mb/s. Standard VDSL deployment uses a frequency spectrum up to 12 MHz, whereas VDSL2 allows for up to 30 MHz as an option.
The capabilities of VDSL are...
