Thank you Charles. I will take a look and other answers are welcome.
Note: I bought the Spectran HF-6080 from Aaronia. Yes I did..
Next week I will do a comparative test with another spectrum
analyser (R&S) at the official Belgian center of EMF control (BIPT),
and will see what it gets. I have 30 days for testing.
I saw somewhere in this forum that with a spectrum analyser, for
the "sum" (total) of the field strenght in V/m over a wide
frequency range, the separate values must be raised to the higher
power (max), added together and from the sum, the square root
must be drawn in order to determine the total load in that range.
Is this true ?
If the values are in µW/m², the separate values can just be added
together.
best regards,
Joris Everaert
