Tim,
Clause 5.6 tells you how to measure in the range of 30 MHz to 1 GHz. But that
does not mean you have to measure that entire range, only that the procedure
will work over that range. Clause 4.5 and Table 4 tell you what range you need
to measure and to use the procedure specified in Clause 5.6. Clause 4.5 and
Table 4 are controlling in this case.
Regards,
Scott

In EN55013, Clause 5.6 Measurement of disturbance power of associated
equipment (video recorders
excluded) in the frequency range 30 MHz to 1 GH,
It shows up the meaurement frequency range is 30 MHz to 1 GH, however
why we
ususally test it from 30 MHz to 300MHz?
In addition, in Clause 4.5 Disturbance power, Table 4 – Limits of
disturbance power, it also show frequency 30 to 300MHz. Why Clause 5.6 can’t
against table 4.
Thanks
Regards
Tim
