Input-related spurious 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 RS A306B
is less than -60 dBc. A band pass filter or low pass fi lter 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 filter (K&L
5BT-1500/3000-5-N/N), and RSA306B as shown. Connect the power sensor and RF signal generator directly to the
power splitter, which is connected directly to the RSA306B.
NOTE. A lternatively, a 3300 MHz lowpass filter, K&L 5L250-3300/E 10000 -O/OP, may be used instead of the tunable filter.
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 RSA306B to 2190 MHz center frequency.
