Note: In the measurement of the signal with the crest factor n > 1.41 the upper linear operating
range for the RMS value is reduced. Its value can be calculated from the equation:
A
n
= A +10 - 20log (n / ) [m], where A is the given range for the sinusoidal signal. E.g. for n = 10
and A = 180 the value of A
10
is equal to = 173 dB.
