9. Calculate and record the IF feedthrough spur amplitude in dBc (IF amplitude (dBm) +30).
10. Repeat steps 7 through 9 for each center frequency listed in the table. Do not change the signal generator frequency.
11. Record results in the Test record.

IF feedthrough.
12. Set the signal generator to 2440 MHz.
13. Set the signal generator for -30 dBm at the power meter. This is also the amplitude at the input of the RSA306. The
generator amplitude will be close to -24 dBm.
14. Set the RSA306 to the center frequency shown in the first column of the 2440 MHz IF feedthrough table. (See Table 20
on page 44.)
15. Measure and record IF feedthrough spur amplitude.
16. Calculate and record the IF feedthrough spur amplitude in dBc (IF amplitude (dBm) +30).
17. Repeat steps 14 through 16 for each center frequency listed in the table. Do not change the signal generator frequency.
18. Record results in the Test record.
