3-6 Spurious Response (Second Harmonic Distortion)
24. Set the # of Average to 5.
25. Wait until the Trace Count displays "5/5".
26. Touch the Marker main menu button and then Peak Search submenu button.
27. Record the amplitude of 100.2 MHz in
28. Calculate the second Harmonic level in dBc by subtracting the 50.1 MHz amplitude from the 100.2 MHz
amplitude using the following formula:
Second Harmonic level dBc = 100.2 MHz amplitude – 50.1 MHz amplitude
29. Record the calculated Second Harmonic Level in
3-10
Chapter 3 — Spectrum Analyzer Verification
Table A-9.
Table A-9 and verify that it is < –56 dBc.
