Signal Identification
5. The IF output of a harmonic mixer contains many mixer products (frequencies of LO ± source, 2LO
± source, 3LO ± source...nLO ± source). As a result, within a single harmonic band, a single input
signal can produce many responses, only one of which is valid.
These responses come in pairs, where the members of the valid pair are spaced 621.4 MHz apart (see
Figure
2-11) and the right-most member for the pair is the correct response (for this analyzer, the left
member of a pair is not valid).
