Who looks at these measurements,
will see that there are just differences in performance.
And that both the Cisco with linear power supply and the Paul Pang single switch perform well.
In terms of common mode better than the English Electric and NuPrime which are just 10 dBm above it.
In terms of price,
these four are not that different.
What also stands out is that the Paul Pang Quad measures the same on the power supply side as it does on the switch side.
Very good isolation,
in other words.
A negative outlier is – in our opinion – the SOtM.
The price is not in proportion to the performance.
We attribute this purely to the cheap switch mode power supply that they provide.
