SPURIOUS SIGNALS TEST, 22 to 26.5 GHz (Applies only to HP 8340B)
NOTE
Non-harmonically-related
spurious
responses, resulting from mixing
products produced by
two or more signals
within
the HP 8340B, follow
a
mathematical relationship to the signals that generated them.
If
the level
of all such
signals up
to 22
GHz are within the specification, then no
mixing products will
be out of specification above
22
GHz. Therefore, no
test is
provided for non-harmonically-related spurious signals above 22
GHz.
