I'm currently grappling with RF interference issues affecting a condenser microphone, and I suspect it might be digital noise demodulation. In my troubleshooting arsenal, I have an HP3585A spectrum analyzer and a TekBox TBPS01 EMC Near-Field Probe Set. While the spectrum analyzer has a limited range of 40MHz, I believe it could offer valuable insights.
My initial strategy involves inserting the near-field probe into the microphone body through the XLR hole and comparing the obtained results with background noise. To expand my options, I'm contemplating crafting an XLR to SMA connector adapter or creating a custom small EMC probe that I can mount in place of the microphone capsule.
Additionally, I'm exploring the possibility of using the tracking generator output as a noise source to perform a frequency response analysis.
Thank you for your expertise!

- Has anyone done anything like this to address digital noise demodulation in condenser microphones, and do you have any recommendations for its effective use in this scenario?
- Are there considerations or precautions I should be aware of when crafting XLR to SMA adapters or custom EMC probes for microphone interference troubleshooting?
- Regarding the tracking generator output, has anyone used it as a noise source for conducting a frequency response analysis, and what insights can you share on this approach?
