Input-related spurious response: RF X 3LO
NOTE. You do no
t need to do the first three steps (setup, reset, and alignment) when you perform the input-related spurious
response tests in sequence.
1. Connect the signal generator, power splitter, power sensor, power meter, and RSA306B as shown. Connect the power
sensor and RF si
gnal generator directly to the power splitter, which is connected directly to the RSA306B.
2. Reset the RSA306B to factory defaults (Presets > Main).
3. Run the RSA306B alignment procedure (Tools > Alignments > Align Now).
4. Set the RSA306B as follows:
a. Reference Level = –30 dBm
b. Span = 1MHz
c. RBW = 1kHz
d. Detection mode = +PEAK (Setup > Settings > Traces > Detection > +PEAK)
e. Function = Avg (Vrms) (Setup > Settings > Traces > Function)
f. Averaging = 10 (Setup > Settings > Traces > Function: count = 10)
g. Select External Reference (S etup > Acquire > Frequency Reference > External)
5. Set the signal generator for -30 dBm at the power meter. This is also the amplitude at the input of the RSA306B. The
generator amplitude will be close to -24 dBm.
6. Set the RSA306B to the center frequency shown in the first column of the RF X 3LO table. (See Table 22 on page 50.)
7. Set the signal generator to the frequency shown in the second column of the RF X 3LO table.
8. Set the signal generator for -30 dBm at the power meter.
9. Measure and record the RF X 3LO spur amplitude.
10. Calculate and record the RF X 3LO spur amplitude in dBc (RF X 3LO amplitude (dBm) +30).
