Input-related spu rious response: signal 2RF X 2LO
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.
NOTE. The 2RF X 2LO specification applies when the second harmonic distortion of the signal at the input of the RSA306 is
less than -60 dB c. A band pass filter or low pass filter is used to attenuate the second harmonic distortion of the generator.
1. Connect the signal generator, power splitter, power sensor, power meter, tunable band pass fi lter (K&L
5BT-1500/3000-5-N/N), and RSA306 as shown. Connect the power sensor and RF signal generator directly to the
power splitter, which is connected directly to the RSA306.
NOTE. You will replace the tunable band pass filter with a low pass filter later in the procedure.
2. Reset the RSA306 to factory defaults (Presets > Main).
3. Run the RSA306 alignment procedure (Tools > Alignments > Align Now).
4. Set the RSA306 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 (V rms) (Setup > Settings > Traces > Function)
f. Averaging = 10 (S etup > Settings > Traces > Function: count = 10)
g. Select External Reference (Setup > Acquire > Frequency Reference > External)
5. Set the RSA306 to 2190 MHz center frequency.
