15.Verify that the marked signal is a true response and not a random noise peak by pressing SINGLE to trigger a new sweep and press PEAK SEARCH. A true response will remain at the same frequency and amplitude on successive sweeps but a noise peak will not.
If the marked signal is not the fundamental or a harmonic of the fundamental (see step 14) and is a true response (see step 15), proceed with step 17.
16.If the marked signal is either the fundamental or a harmonic of the fundamental (see step 14) or a noise peak (see step 15), move the marker to the next highest signal by pressing SHIFT, PEAK SEARCH. Repeat step 14.
The following step is only performed if the marker signal is not the fundamental or harmonic of the fundamental and is a true response.
17.Calculate the dierence between the amplitude of marked signal and the Fundamental Amplitude as listed in Table
For example, if the Fundamental Amplitude for a fundamental frequency of 9 kHz is +1.2 dBm and the marker amplitude is 030.8 dBm, the dierence is 032 dBc.
Record this dierence as the
