RESULTS AND

CALCULATIONS

S(dB) = S(dB)

susceptor + S(dB)

radiator

S(dB) = 30 + 35

= 65

Repeated step V3(dBV) = -173 + 65

= -108

5 inches (spacing with both

cables shielded)

Adequate shielding

NOTES

S(dB) susceptor = 30 dB from first step 5.

Rigid metal conduit used for shielding

radiator (see paragraph 6.7.2).

S(dB) radiator = 35 dB from figure 6-7.

V3(dBV) = V1(dBV) + S(dB) of repeated-

step 5.

Figure 6-5 (note 4).

Cable designator is S4-4.

Figure 6-6. Intersection of coordinates R1-4

and S4-4.

Required spacing in repeated-step 8 is

equal to available spacing in step 4. The 5-

inch spacing with shielding must be

maintained as a minimum spacing

requirement.
