Harmonic Comb Generators Are Useful Tools
By Kenneth Wyatt INTRODUCTION One tool every EMC test lab should own is a harmonic comb generator. A comb generator is simply a device that will produce a set of harmonically related CW signals whose spacing is based on a fundamental oscillator frequency. For example, if we were to start with a 10 MHz clock oscillator and feed the digital output into a coax connector, we’d … [Read more...]
Tech Tidbit: Gwyneth Paltrow has ‘Golden Halo’ in Electromagnetic Image of Aura
