Jim, Answer to your question is no, preselector is not required.
Receivers including spectrum analyzers for testing to all three standards you mentioned are described in details in CISPR 16-1:1993-08 Specifications for radio disturbance and immunity measuring apparatus and methods, SECTION 1: Measuring apparatus.
