Nano VNAs Explained

"Nano VNAs Explained" by Mike Richards, G4WNC is a practical guide to Nano Vector Network Analyzers for new users or those who occasionally use their NanoVNA. If you are considering buying a NanoVNA or already own one, this book will ensure that you get the most from these incredibly useful devices.

Vector Network Analyzers (VNAs) have traditionally been out of reach for most radio amateurs because of cost, but the introduction of low-cost NanoVNAs has changed this. VNAs are incredibly useful in measuring antennas, but they are capable of much more! However, getting the most out of these devices is not as easy as it could be and this book, "Nano VNAs Explained" by Mike Richards, G4WNC fills in the gaps for the casual NanoVNA user. Broken into two parts, "Nano VNAs Explained" by Mike Richards, G4WNC will show you the basics of the use of a VNA and then expands on that knowledge to get much more from these handy devices.

Part One Introduces you to the essential elements such as smith charts, S parameters and calibration while avoiding the associated complex math. Computer control is available for the NanoVNA and you will find a section on how to make the most of the available software. Alongside these 'how-to guides' Mike also analyzes the different NanoVNA hardware models and details about updating their firmware.

Part Two gives practical examples of a wide range of VNA-based measurements. Besides a section on antennas, you will find guides to ATU settings, feeder loss, resonant stubs, time-domain reflectometry (TDR), RF switches and relays, passive filters, active filters, amplifiers, attenuators, directional couplers, RF taps, common mode chokes, baluns, ununs, splitter/combiners, crystals and cable checkers.

Detailed illustrations, combined with step-by-step guides to each measurement, will increase your chances of achieving accurate results.
