Input-related spurious response: IF feedthrough
NOTE. Youdono
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 RSA306 as shown. Connect the power
sensor and RF signal generator directly to the power splitter, which is connected directly to the RSA306.
2. Reset the RSA306 to factory defaults (Presets > Main).
3. Run the RSA 306 alignment procedure (Tools > A lignments > Align Now).
4. Set the RSA306:
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 (Setup > Acquire > Frequency Reference > External)
1190 MHz IF feedthrough.
5. Set the signal generator to 1190 MHz.
6. 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.
7. Set the RSA 306 to the center frequency shown in the first column of the 1190 MHz IF feedthrough table. (See Table 19
on page 44.)
8. Measure and record the IF feedthrough spur amplitude.
