EDITOR’S CHOICE PRODUCTS FEATURING FDA OPTION
Keysight Technologies, Inc. has released a frequency domain analysis (FDA) option, which it claims is the industry’s first user- extensible spectrum frequency domain analysis application solution for real-time oscilloscopes. The FDA option extends the capabilities of the company's
Infiniium and InfiniiVision Series oscilloscopes by enabling engineers to acquire live signals from the oscilloscope and visualise them in the frequency domain as well as make key frequency domain measurements. Option N8832A-001 includes the application, the application source code for user extensibility, and MATLAB software. These tools allow engineers to extend the application’s capabilities to meet their current and future testing needs. The FDA application provides capabilities for addressing issues
with power spectral density (PSD) and spectrogram visualisation, commonly found in spectrum analyser and frequency domain analysis software. The device handles frequency domain measurements in an
application including relevant peaks in the PSD and measurements such as occupied bandwidth, SNR, THD (total harmonic distortion), SFDR (spurious free dynamic range) and frequency error. Oscilloscope configuration is supported through the
application to allow for repeatable instrument configuration and measurements; optionally includes additional SCPI commands for more advanced instrument setup. Insertion of additional custom signal processing commands can be carried out prior to frequency domain visualisation, as needed, for more advanced analysis insight.

NEW PRESS-FIT VERSIONS Press-Fit versions have
been added by Semikron to its Semitop family of power modules. This alternative technique ensures easy and fast mounting of the module and PCB in one step, reducing assembly time
and cost by eliminating the solder process. The 100% pin-out compatibility with the soldered version provides a press-fit interface and the new modules are characterised by the same electrical and thermal performance as the existing solder version. This device is an isolated power module based on baseplate-free
technology with only one mounting screw for heat sink fixing. The pressure technology concept and the single mounting screw guarantee a low thermal resistance and reduced mechanical stress for high reliability. The product reliability is tested and confirmed by the company's extended qualification programme, consisting of as many as 17 different qualification and reliability tests. Some of these exceed industrial standards, with a duration of more than 2500h. A large variety of configurations with different chip technologies
are available in SEMITOP4 (60x55mm), SEMITOP3 (55x31mm), and SEMITOP2 (40.5x28mm) Press-Fit cases. New high-performance configurations such as 3-level inverter (NPC) and mixed 3-level inverter (TNPC), double boost and interleaved boost applications are available, as well as standard and established configurations, including 3-phase inverter, converter-inverter-brake solutions, MOSFET configurations and 3-phase bridge rectifiers.
