analyzer to the next highest signal by pressing NEXT PEAK. Repeat
step 4 above.
Perform step 7 only if the marker signal is a true response and not a
fundamental or harmonic of the fundamental. Otherwise, continue
with step 8.
7. Calculate the difference between the amplitude of marked signal
and the fundamental amplitude as listed in Table 2-101.
For example, if the fundamental amplitude for a fundamental
frequency of 10 MHz is 1.2 dBm and the marker amplitude is
−40.8 dBm, the difference is −42 dBc.
Record this difference as the non-harmonic response amplitude for
the appropriate analyzer center frequency and microwave analyzer
start and stop frequency settings in Table 2-102.
8. If a true non-harmonic spurious response is not found, record
“NOISE” as the Amplitude of Non-Harmonic Response in Table
2-102 for the appropriate analyzer center frequency and microwave
analyzer start and stop frequency settings.
9. Repeat step 1 through step 8 for the remaining analyzer center
frequency and microwave analyzer settings in Table 2-102.
