26 | Performance, Theory, Measurement
The following graph shows the computed versus theoretical conversion factor for
the Model 7604. The data obtained by measurement is within 0.5 dB of
theoretical values computed. Because of the probable amount of measurement
inaccuracy, especially at the lower frequencies, the computed conversion factors
are more accurate and are therefore preferred.
