Procedure 1 - Determining Cable-to-Cable Spacing and Shielding for
Radiators Versus Susceptors in Susceptor Categories S1, S2, and S4 (Continued)
STEP NO.
DETERMINE THE FOLLOWING
VALUES
Repeated S(dB) = S(dB) susceptor +

Repeated V₃(dBV)

INFORMATION SOURCE OF
INSTRUCTION
S(dB) susceptor from first step 5.
S(dB) radiator from figure 6-7.
(See paragraph 6.7.2.)
V₃(dBV) - V₁(dBV) + S(dB) from repeated-step

Repeated Adequate shielding or inadequate
step 9
shielding
If required spacing in repeated-step 8 is less
than or equal to available spacing in step 4,
adequate shielding has been provided.
If required spacing in repeated-step 8 is
greater than available spacing in step 4, the
following solutions apply:
a. Remove physical restrictions to increase
available spacing.
b. Reroute radiator and/or susceptor.
