English to Russian Tech/Engineering Electronics / Elect Eng испытания ретранслятора

Уважаемые, перевожу мануал по ТУ на спутник связи, раздел испытаний ретранслятора при его интеграции на КА.
вот раздел с сабжем:
SOT selection
As general rule, three main ‘interface points’ are devoted to SOT selection:
• Section in front of the input coaxial switch matrix (KIPSM), where SOT will be identified to drive each Down Converter inside the specified input level range.
• Section before the LCAMPs, where SOT will be identified to drive each unit inside the specified input level range including 10 dB of IBO against the TWTA saturation
• Section after the LCAMPs, where SOT will be identified to drive their following TWTA’s at saturation point. The SOT shall be evaluated by making the difference between Channel Amp Supplier’s data (attenuation to be provided towards TWTA) and the real Input Loss due to Cable length interconnecting CAMP output to TWTA input. This evaluation shall be done for each pair CAMP+TWTA.
A first set of SOT values will be provided before the integration test phase. After further analysis, this set will be verified on relevant configurations during the performances test phase.
По ТМ сабж = набор специальных аттенюаторов, но в контекст это не лезет
Сокращения: LCAMP - линеаризованный канальный усилитель, TWTA - усилитель на лампе бегущей волны, IBO (input back-off) - ослабление на входе (отн. уровня насыщения)
