Figure 2-12. Main display for Static Multipath Fading
To avoid clipping when fading is enabled, the power of the signal
under fading conditions must be reduced to less than the instrument’s
normal maximum power. When fading is enabled, the input signal must
be limited to less than -6 dBm, and the resulting faded output signal
power will be less than -19 dBm (dependent upon the path loss
settings).
