10. S et the signal generator frequency to 72 MHz.
NOTE. Do not ch
ange the center frequency of the RSA306B.
11. Set the signal generator amplitude for –30 dBm on the power meter. This amplitude is also at the RSA306B input. Note:
In this case, the signal generator setting will be near –24 dBm.
12. S et the RSA306B marker on the image spur at 40 MHz, right edge of the span. Note its amplitude in the table.
13. Calculate and record the image amplitude in dBc:
Image (dBc) = Image amplitude at 40 MHz – CW amplitude at 21 MHz
RF ADC imag
e.
14. S et the signal generator frequency to 140 MHz.
15. S et the signal generator amplitude for –30 dBm at the power meter. This amplitude is also at the RSA306B input. The
signal generator setting will be near -24 dBm.
16. S et the RSA306B Center Frequency to 140 MHz.
17. P eak the marker on the CW signal at 140 MHz. Record the value in the ADC measurements table. (See Table 1 6
on page 40.)
18. S et the signal generator frequency to 103.8 MHz.
NOTE. Do not change the center frequency of the RSA306B.
19. S et the signal generator amplitude for –30 dBm on the power meter. This amplitude is also at the RSA306B input.
20. S et the RSA306B marker on the image spur seen at 120.2 MHz, at left edge of the span. Record the amplitude in the
ADC measurements table.
21. S et the signal generator frequency to 176.2 MHz.
NOTE. Do not change the center frequency of the RSA306B.
22. S et the signal generator amplitude to –30 dBm on the power meter. This amplitude is also at the RSA306B input.
23. S et the RS A306B marker on the image spur seen at 159.8 MHz, at right edge of the span. Record the amplitude in the
ADC measurements table. Mark which image amplitude is larger: 159.8 MHz, or 120.2 MHz.
24. Calculate and record the l argest image amplitude in dBc:
Image (dBc) = Largest Image amplitude at (120.2 MHz or 159.8 MHz) - CW amplitude at 140 MHz
25. R ecord results in the Test record.
