| 3.3.7.2 MAXIMUM PAYLOAD EMISSIONS The emission envelope for Dedicated Rideshare Missions and Secondary Rideshare Missions, including 6 dB of EMI safety margin by test, or 12 dB of EMI safety margin by analysis, is shown in Table 3-10. Table 3-10: Maximum Payload Emissions Frequency Range MHz) Dedicated Rideshare Secondary Rideshare by Test (dBμV/m) by Analysis (dBμV/m) by Test (dBμV/m) by Analysis (dBμV/m) 30.0 – 1555.42 90 84 48 42 1555.42 – 1595.42 48 42 48 42 30.0 – 18000.0 90 84 48 42 Standard launch services do not permit use of Payload transmitters while integrated to the Launch Vehicle hardware. Payload transmitters maybe enabled after the time interpolated using the information found in Table 3-11 for Dedicated Rideshare Missions and Table 3-12 for Secondary Rideshare Missions. Additionally, any transmitter centered in the (2227.5 - 2237.5 MHz, (2267.5 - 2277.5 MHz, and (2206 - 2216 MHz) bands must wait to enable these transmitters until End of Mission as defined by the Mission-specific second stage reentry time (usually a maximum of 1 hour, or 3600 seconds, after the first deploy.
