I'm working on solving an issue in a metal detector that generates false detects when subject to electrical interference. The electrical interference usually stems from devices such as shortwave radio (walkie talkies) when being used in proximity, HF fluorescent lighting, Variable Frequency Drives etc.
I want to design/buy a system that can produce these frequencies with low energy. The idea being that I can repeatedly subject the metal detector to noise to understand the behaviour of the metal detector and in turn design a solution that mitigates the effects of the environmental noise.
- Could I achieve this with a software defined radio?
- If not, could I achieve what I want with a signal generator, a power amplifier and an antenna?
I understand that there may be concerns about intentionally generating radio frequencies but I'll ask that in an other question.
