Spurious Signals Test, 22 To 26.5 Ghz (Applies Only To Hp 8340B); Harmonics; Non-Harmonically Related Spurious (Cw And Manual Sweep Mode Only) - HP 8340B Manual

4-8. SPURIOUS SIGNALS TEST, 22 to 26.5 GHz (Applies only to HP 8340B)

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.
