Using

Traces
Distortion
from
the
Analyzer
High-level input signals may cause spectrum analyzer distortion products that
could mask the real distortion measured on the input signal. Using trace B
and the RF’ attenuator, you can determine which signals, if any, are internally
generated distortion products.
