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.
The SQ series of handsfree probes from Sensepeek have a lower point of gravity making them even more stable compared with the original SP series of handsfree probes. All probes in the SQ series are also insulated and can be used handheld as any traditional probe but their full potential is used when measuring handsfree.
The SQ series of oscilloscope probes also includes more ground options, have probe tip protection, longer cable and support for oscilloscopes with automatic scaling (10:1).
All the loved features of handsfree measurement, exchangeable fine pitch spring tipped test needle, color-coded cable holders and the minimalistic design is maintained to make traditional sized and handheld probes obsolete.
Both length and weight of the SQ probes are perfectly balanced to be used with PCBite PCB holders and base plate which is a must for handsfree function.

The FNIRSI SG-003A multi-functional Signal Generator a.k.a. Process Meter/Calibrator is a high-precision voltage/current generator and meter. The SG-003A provides highly accurate reference voltages or currents for testing and calibrating other measurement instruments like multimeters and oscilloscopes.
Besides voltages and currents, the SG-003A also generates rectangular pulse signals with precisely programmable frequencies and duty cycles. Its converter mode turns the SG-003A into a precision voltage-controlled current source, or current-controlled voltage source, and even a voltage- or current-controlled frequency generator.
The SG-003A is a great tool for checking your multimeter’s accuracy and precision, and for testing e.g. LEDs.
