Figure 3-5: Random Vibration MPE
3.3.7

ELECTROMAGNETIC
Purpose: To ensure that Launch Vehicle and launch site radiated emissions do not compromise electrical integrity of the Payload, and to ensure that Payload emissions do not compromise safety of the Launch Vehicle or of Co- Payloads during the mission. The Payload must show compliance with the electromagnetic environments in the following sections. Payload electromagnetic specifications will be captured in the Payload-specific ICD.

14 Verification Testing or verification by analysis is REQUIRED to the electromagnetic compatibility test levels and durations defined in Table 3-15 in accordance with the environments defined in this section.
3.3.7.1

IN-FLIGHT AND PRE-FLIGHT ENVIRONMENTAL EMISSIONS
Customer must ensure that Payload materials or components sensitive to RF environments are compatible with the worst-case radiated environment shown in Figure 3-6. Launch Vehicle, including Co-Payloads, and Launch Site radiated emissions, are shown in Table 3-8 and Table 3-9 respectively. EMI margin is not included.
Figure 3-6. In-Flight & Environmental Radiated Emissions / Payload Radiated Susceptibility Limit
Table 3-8: Launch Vehicle Radiated Emissions
Frequency Range (MHz)
E-Field Limit (dBμV/m)
1.00 – 2200.0 120 2200.0 – 2300.0 140 2300.0 – 18000.0 120
Table 3-9: Launch Site Radiated Emissions
Frequency Range (MHz)
E-Field Limit (dBμV/m)
1.00 – 100 120 100 – 400 132 400 – 1200 140 1200 – 1400 148 1400 – 11000 146 11000 – 18000 120 These limits envelope the expected emissions from the Launch Vehicle, Co-Payloads, and Launch Site radar transmitters. Customer should assume 26 dB of shielding from Launch Site sources when testing and integrating the Payload in either the PPF or the Hangar Annex.
