Figure 5: Signal Strength Reading

Figure 6: BER(-102 dBm)

When using JXS-1 shield box different RF attenuations have to be used. It is recom-
mended that in the shield box all measurement are performed only on

channel 661

and

additional 2.5 dBm loss in added to Reference level offset, so that total RF attenuation
caused by JXS-1 shield box and CPL-6 Adapter is

6.5 dBm+ cable loss
