19. Set the UUT as follows:
Mode Leveled Sine
Signal Microwave Output
Frequency 4.399994 GHz
Level +4.6 dBm
Output OPER
20. Set the Spectrum Analyzer to single sweep, initiate a sweep and wait for the
sweep to complete. Push MARKER
→ PEAK.
21. Using the spectrum analyzer marker delta functions, measure the amplitude
of any spurious signals detected. Verify any spurious signals at offsets
>±3 kHz from the output frequency and within the range of ±1 MHz are within
the listed limits.
22. Set the output frequency of the UUT and the spectrum analyzer center
frequency to each of the frequencies listed in Table 3-30, repeating steps 20
and 21.
23. Set the UUT output to STBY.

Note
The Microwave output signals at 4.024 GHz use the same
frequency generation and synthesis circuits that are tested during
the Leveling Head output spurious content tests. For signal outputs
at >4.024 GHz frequency multiplication techniques are used, and no
additional spurious generation mechanisms are present. Therefore,
Microwave output spurious content testing is not required to
adequately verify Product performance.
