The LISN on this great video, is this serial product or just for your own lab purposes, I am interested to know if they are for sale for the price. I couldn't found nothing on google for this LISN, thanx
Is it the differential-mode noise that you see on the Spectrum Analyzer or the common-mode noise or a mix of both? Also, as I saw, nothing changed on the Spectrum Analyzer when you removed 50 ohm terminator from LISN channel N. What was supposed to happen if the two lines (L and N) are not symmetric?
With a standard LISN it's always a mix of common-mode and differential noise. You'll need extra circuitry to separate CM from DM noise. Basically a circuit that adds (for CM) or subtracts (for DM) the two measurement ports of a LISN. So you'll either need a LISN with two measurement ports or two LISNs.
Is this LISN for sale somewhere or is it a single piece? I'm having a hard time finding an affordable LISN with two measurement ports and dedicated connections for DC and AC power lines.
