Radio Frequency Network Analyzers is one important tool required for testing the frequency response of filters and networks, but as we all know, buying a regular RF test equipment can be quite the expenditure. This was why hobbyist Stephen Merrifield, who after seeing the increased need for more RF testing capabilities as a result of […]

M0xpd documented his experience building DuWayne’s Scalar Network Analyzer Jr: DuWayne’s project uses an AD9850 in one of our familiar modules to generate RF, under the control of an Arduino NANO. You can read on DuWayne’s blog how the SNA Jr is the descendant of earlier experiments in which an Si5351 was used as the signal […]

Ham radio is the use of radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, etc. Developing a ham radio project may requires using an antenna analyser, a device that is used for measuring input frequency and impedance. There are many types of antenna analysers such as Anritsu VNA Master, RigExpert, […]
