Field Strength of Fundamental Emission (47 CFR 15.209) Measurements were made using a peak detector. Field strength of the peak fundamental emission is shown in Tables 3 and 4. Duty Cycle Correction During 100 msec: Each setting sends a different series of characters, but the worse case transmit cycle consists of 20.5 ms of transmit time every 35.5 ms (57.7 % Duty Cycle). Figure 3 shows the characteristics of the pulse train for one of the various functions. Duty Cycle Correction = 20 log (0.577) = -4.8 dB
