10 MHz Output Spurs T est
5. Connect the RF OUTPUT of the synthesized source to the DUT's EXT REF input. Press
4 RECALL 5 4 1 5 on the synthesized-source front panel to set the synthesized-source frequency
and amplitude to the settings saved in step 1.
6. Set the spectrum-analyzer center frequency to 10 MHz, frequency span to 50 kHz, and
reference level to +10 dBm.
7. Set the spectrum-analyzer marker to the highest peak and note the carrier amplitude . It
should be approximately 0 dBm.
8. Set the spectrum-analyzer center frequency to 1 MHz, frequency span to 50 kHz, and
reference level to 020 dBm . All signals should be at least 80 dB below the carrier level
noted in step 7.
9. Change the spectrum-analyzer center frequency setting to 9 MHz. All signals should still be
at least 80 dB below the carrier level noted in step 7.
10. Change the spectrum-analyzer center frequency setting to 11 MHz. All signals should still
be at least 80 dB below the carrier level noted in step 7.
11. Press 4 RECALL 5 4 2 5 on the synthesized-source front panel to set the synthesized-source
frequency and amplitude to the settings saved in step 2.
12. Set the spectrum-analyzer center frequency to 2 MHz, frequency span to 50 kHz, and
reference level to 020 dBm . All signals should be at least 80 dB below the carrier level
noted in step 7.
13. Change the spectrum-analyzer center frequency setting to 8 MHz. All signals should still be
at least 80 dB below the carrier level noted in step 7.
14. Change the spectrum-analyzer center frequency setting to 12 MHz. All signals should still
be at least 80 dB below the carrier level noted in step 7.
15. Press 4 RECALL 5 4 3 5 on the synthesized-source front panel to set the synthesized-source
frequency and amplitude to the settings saved in step 3.
16. Set the spectrum-analyzer center frequency to 5 MHz, frequency span to 50 kHz, and
reference level to 020 dBm . All signals should be at least 80 dB below the carrier level
noted in step 7.
17. Change the spectrum-analyzer center frequency to 15 MHz. All signals should still be at
least 80 dB below the carrier level noted in step 7.
18. Press 4 RECALL 5 4 4 5 on the synthesized-source front panel to set the synthesized-source
frequency and amplitude to the settings saved in step 4.
19. Set the spectrum-analyzer center frequency to 10 MHz, frequency span to 5 kHz, RES BW
to 30 Hz, VIDEO BW to 10 Hz, and reference level to +10 dBm.
20. Set the spectrum-analyzer marker to the highest peak and note the carrier amplitude . It
should be approximately 0 dBm.
21. Set the spectrum-analyzer center frequency to 10.04 MHz, frequency span to 5 kHz,
RES BW to 30 Hz, VIDEO BW to 10 Hz, and reference level to 020 dBm. All signals should
be at least 80 dB below the carrier level noted in step 20.
22. Change the spectrum-analyzer center frequency setting to 10.08 MHz, frequency span to
10 kHz, and VIDEO BW to 30 Hz. All signals should be at least 80 dB below the carrier
level noted in step 20.
