1 Introduction
The SARK100 SWR Analyzer is yet another antenna analyzer but available in kit form and
designed to be easy to assemble and with an affordable pricing. You will enjoy of this DIY
experience that it will not only help for improving your SMD soldering skills and learn about the
analyzer basics but you will get a useful instrument for your shack. In addition you will have the
possibility of modifying and updating the analyzer software via USB at your convenience, but
even more, part of hardware is software configurable because of the programmable features of
the PSoC micro-controller. For instance, you can change the ADC type, increase or decreasing
the resolution or the sample rate, etc; therefore it is excellent training kit for the learning of the
PSoC microcontroller.
This kit requires some soldering skills so I would not recommend it if it is your first experience
with the soldering iron. In this case it is better starting with a kit based on trough-hole
components. If you have experience with the soldering iron but you are new to the SMD, don’t
be afraid, it is much easier that it seems using the correct technique and (basic) tools. It is a kit
with a moderate component count so once you have completed I’m sure that you will be more
confident to embrace the building of more complex SMD kits.
This manual includes everything you need to know about the SARK100, including the assembly
guide, technical descriptions, operating guide, and detailed technical information including
schematics and diagrams. Please visit the project website (http://www.ea4frb.eu/sark100.html)
to access the updates and latest versions of software.
This kit is an amateur project developed in my spare time, and so no commercial backing
possible. You should be aware of this and accept as is; otherwise you will find in the market a
variety of finished products or similar kits. In any case I have made every reasonable effort to
allow you having success with the assembly. Please do not hesitate to contact me to give me
opinions about the kit or have questions. I thank you for buying the kit and I wish you luck in the
construction and use!
Sincerely,
