11. Repeat steps 5 through 10 for all output and harmonic frequencies in
Table 3-29, using the settings and limits shown for each.
12. Set the UUT as follows:
Frequency 4.05 GHz
Level +16 dBm
Output OPER
13. Set the Spectrum Analyzer as follows:
FREQ 4.05 GHz (fundamental)
14. On the Spectrum Analyzer, push MARKER
→ PEAK.
15. Set the Spectrum Analyzer as follows:
FREQ 6.075 GHz (interharmonic)
16. Using the Spectrum Analyzer delta marker functions, measure the amplitude
on the Spectrum Analyzer for the UUT's interharmonic relative to the
fundamental. The displayed (delta marker) value must be within the
tolerance listed in Table 3-30 for interharmonics.
Note
Refer to the notes in steps (4) and (8) above regarding avoiding
overloading the spectrum analyzer mixer and observing and
measuring interharmonic signals on the analyzer display at or below
the tolerance limits with the above analyzer settings.
17. Repeat steps 13 through 16 for all output, sub harmonic, and interharmonic
frequencies in Table 3-30, using the settings and limits shown for each.
