Test 2-10: Spurious/Non-Harmonic Distortion (cont’d)
Test Procedure
(cont’d)
Perform steps 3 and 4 for each frequency range listed in Table 2-10:
3. Set the Spectrum Analyzer start frequency and stop frequency to the
values listed in Table 2-10.
4. Measure the amplitude (in dBm) of the highest peak. Subtract the
amplitude of the fundamental (-5dBm) from the reading and record
the result in Table 2-11:
result (dBc) = reading (dBm) − (−5 dBm)
