Re: Measuring AC Power Line Noise
Hold on. I just wrote:
the Trifield EMI meter measures (higher frequency) noise voltage fields in the air.
So I went to the Trifield page:EM100 - Power Line Monitor - TriField
And that's not how EM100 Power Line Monitor works, it connects directly to the AC line!!!
it:
It immediately displays total line noise in millivolts peak to peak (range 1999.9 mVp-p, resolution 0.1 mVp-p) in the frequency range 10 KHz – 10 MHz
10 kHz is in the noise frequency range of concern.
can't find the users manual for that model.

Re: Measuring AC Power Line Noise
Thanks for the reply. I built my home and had three dedicated lines with separate ground installed in my music room. When I measured them with the Trifield meter they were only marginally "quieter" than my regular outlets. All my outlets seem to be pretty "quiet," though so I am satisfied.

Re: Measuring AC Power Line Noise
Much of the lower frequency current line noise is generated by big power amplifiers with linear power supplies.
While audio components with SMPS (supplies) may generate higher frequency noise or be very quite.
Most nearby modern high tech lighting, appliances, HVAC and other date & entertainment equipment will also have a SMPS and often generate a lot of noise. But you can simply test them for audible noise by turning them on/off one at a time.

I upgraded the power supply on my Gigafoil v4 to a Weiss PSU 102. It’s very nice step up. But with the new model, you’re looking at $2000 before even investing in a SOTA linear power supply.
