The Peak Atlas ZEN50 is ideal for testing Zener diodes (including avalanche diodes), transient suppressors, LEDs and LED strings. It generates constant current pulses (selectable from 2 mA, 5 mA, 10 mA and 15 mA) at voltages from 0 V to 50 V. So even high voltage Zeners or high voltage LED strings can be tested. Test currents are supplied in narrow pulses to ensure that the component under test remains at a constant temperature. The voltage of the part is displayed on the screen together with the test current and also a measure of the component's slope resistance (also known as dynamic impedance). Specifications Analyzer type Zeners, LEDs, TVS etc Test currents 2 mA, 5 mA, 10 mA, 15 mA Voltage range 0.00 to 50.00 V Slope resistance range 0 to 8000 Ohms Battery type Single AAA (supplied).

Die Hochfrequenztechnik ist eines der Gebiete, auf denen man auch heute noch eigene Ideen in die Tat umsetzen kann. Unzählige Schaltungsvarianten mit besonderen Zielsetzungen geben Raum für sinnvolle Experimente und Projekte. Vieles kann man nicht einfach kaufen. Detektorradios ohne eigene Energiequelle, einfache Röhrenempfänger mit einem Hauch von Nostalgie, die ersten Empfangsversuche mit dem Software Defined Radio oder Spezialempfänger für den Amateurfunk, all dies lässt sich mit wenig Aufwand realisieren. Lange Zeit war das Radiobasteln der Einstieg in die Elektronik. Inzwischen gibt es auch andere Wege, vor allem über Computer, Mikrocontroller und die Digitaltechnik. Allerdings kommen die analogen Wurzeln der Elektronik oft zu kurz. Die Radiotechnik eignet sich besonders gut als Lernfeld der Elektronik, weil man hier mit den einfachsten Grundlagen beginnen kann. Aber auch die Verbindung zur modernen Digitaltechnik liegt auf der Hand, wenn es z. B. um moderne Abstimmverfahren wie PLL und DDS oder um moderne DSP-Radios geht. Dieses Buch gibt einen Überblick und stellt eine Sammlung einfacher Projekte vor. Der Autor möchte Sie dabei unterstützen, eigene Ideen zu entwickeln, eigene Empfänger zu entwerfen und sie zu erproben.

Programming with GNU Radio HackRF is an open-source hardware platform developed by Great Scott Gadgets and serves as a versatile front end for software-defined radio (SDR). With HackRF One and its successor, HackRF Pro, users can develop their own SDR applications, build powerful receivers and transmitters, and tackle demanding RF measurement tasks. This book provides a practical introduction to the world of SDR. Step by step, the author shows how powerful SDR projects can be implemented with HackRF – from the fundamentals of RF technology to advanced applications using GNU Radio. In addition to working with SDR Sharp (SDR#), RadioConda, and GNU Radio, the book also covers the fundamentals of modern digital signal processing. Numerous experiments and easy-to-follow practical examples guide readers through topics such as AM, FM, and SSB reception, digital filters, shortwave radio, amateur radio, signal generators, and custom RF projects up to 6 GHz. Whether you are a maker, radio amateur, electronics enthusiast, or SDR beginner, this book provides solid knowledge, practical applications, and the motivation to creatively explore the possibilities of modern SDR technology.

Praktischer Einstieg mit Arduino, GnuRadio und FPGA Das Thema „Software Defined Radio“ ist facettenreich: Neben der Schaltungstechnik ist auch eine Einarbeitung in die Programmierung von Hardware und PC wichtig. Ein schrittweises Vorgehen erleichtert Ihnen den Einstieg. Mit dem im Buch vorgestellten modularen „RF Bricks“-Konzept werden Sie zum Architekten Ihrer Signalkette. Auf einem Chassis angeordnet gewährleisten die Module einen soliden und gut abgeschirmten Aufbau, den Sie einfach verändern und mit eigenen Ideen anreichern können. Der skalierbare Aufbau bildet Ihr Blockschaltbild auch mechanisch ab – die so gewonnene Übersicht kann in der Aus- und Weiterbildung nützlich sein. Ein Arduino in Ihrem Chassis kommuniziert nach einigen Anpassungen mit üblichen SDR-Programmen, z. B. SDRCPP, GQRX und CubicSDR auf einer Linux-Plattform. Damit können Sie Ihren Empfänger direkt per Mausklick abstimmen. Wenn Sie Blockschaltbilder mögen, ist GnuRadio ein natürlicher Partner der „RF Bricks“. Mit einem selbst programmierten Python-Block gelingt Ihnen in GnuRadio die Fernsteuerung Ihres Empfängers. Im GnuRadio-Universum können Sie Ihre GUI stufenweise ausbauen, behalten dabei aber immer volle Kontrolle über die inneren Abläufe des Programms. Mit einem FPGA können zeitaufwändige Operationen auch direkt in die Hardware verlagert werden. Sie bauen stufenweise einen Doppelsuperhet auf und entwickeln die Filterkoeffizienten für FIR-Filter mit Scilab. Das in VHDL realisierte Weaver-Schema rundet diesen Empfänger ab, der mit hoher Empfindlichkeit und Dynamik aufwarten kann. Mit dem gewonnen Überblick und Ihrer neuen Hardware können Sie die einzelnen Aspekte des Themenkomplexes SDR beliebig weiter vertiefen. Downloads Software
