ANSI/EIA RS-426-A method where the test
signal is pink noise with a 6-dB crest factor
over the bandwidth of the system, with
power calculated using E

4. This measurement made under the same
conditions as pressure sensitivity, and takes
into account any power-compression effects
due to nonlinearities in the system.
