Input-related spurious respo nse: fi rst converter images
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 signal 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 output for –30 dBm at the power meter and RSA306B input.
6. Set the RSA306B to the Center frequency shown in the First converter i mages table. (See Table 1 8 on page 44.)
7. Set the signal generator frequency to the Image frequency value in the
table.
NOTE. Monitor and set the signal generator amplitude to –30 dBm whenever you change frequency settings during this test.
8. Measure and record the Image Amplitude at the RSA306B CF.
