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...

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,...

Timing components such as low jitter oscillators and clocks are necessary to facilitate increasing data rates in high speed digital designs. As part of the overall system design, the components also have to perform in the system’s non-ideal power integrity environment and limit the power supply induced phase noise...

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...

Analyzing RF pulses is a key aspect of pulsed radar applications, e.g. in air traffic control (ATC), maritime radar or scientific measurements of the ionosphere. It is essential to analyze the pulse envelope in the time domain because it contains important information needed to characterize the application.

The pace of innovation has changed. Original equipment manufacturers (OEMs) can no longer take years to introduce new products or update functionality in existing products. If your customers can’t get what they want, when they want it, they’re quick to go elsewhere.
OEMs in nearly every industry are becoming...

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...

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...

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,...

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...

All electronic devices contain capacitive or inductive components that can cause a disproportionately high current while switching on the device.
From an FPGA to a drilling machine, virtually every component or device requires an inrush current that by far exceeds the normal operating current. To properly design the...

While almost every power-supply engineer intimately knows and understands the lab setup for measuring efficiency, there are many important nuances that must be considered when measuring the efficiency of a device with ultralow quiescent current (IQ). For a device that consumes less than 1 µA, the circuit’s...

Tin-Silver-Copper alloys are the primary choice for lead-free SMT assembly. Although there are other options available tin-silver-copper solders are by far the most popular.
The lead-free SMT process differs from a 63/37 process in numerous ways. A good understanding of these differences when using SAC...
