Making Basic Measurements Using Spectrum Analyzer Mode

Identifying Distortion Products Using the RF Attenuator and Traces

If the responses in trace A and trace B differ, as in Figure 4-2

1,

then

attenuation is required. If there is no change in the signal level, the distortion

is not caused internally. For example, the signal amplitude in Figure 4-22 is

not high enough to cause internal distortion in the spectrum analyzer so any

distortion that is displayed is present on the input signal
