Page "Ulysses (spacecraft)" Paragraph 27

The spacecraft body is roughly a box, approximately 3. 2 × 3. 3 × 2. 1 m in size.

The box mounted the 1. 65 m dish antenna and the radioisotope thermoelectric generator ( RTG ) power source.

The box was divided into noisy and quiet sections.

The noisy section abutted the RTG ; the quiet section housed the instrument electronics.

Particularly " loud " components, such as the preamps for the radio dipole, were mounted outside the structure entirely, and the box acted as a Faraday cage.
