Spectrum Analyzer Verification 2-4 Spurious Response (Second Harmonic Distortion) Verification
MT8212E and MT8213E MM PN: 10580-00255 Rev. J 2-7
26. Use the keypad to enter 100.2 and press the MHz submenu key.
27. Press the Shift key and then press the Trace (5) key. Then press the Trace A Operations submenu key.
28. Press the # of Averages submenu key, use the keypad to enter 5, and then press the Enter key.
29. Wait until the Trace Count displays “5/5”.
30. Press the Marker key and press the Peak Search submenu key.
31. Record the amplitude for 100.2 MHz in the test records. Use Table A-3.
32. 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 Amplitude at 100.2 MHz =
100.2 MHz amplitude – 50.1 MHz amplitude = _____ dBc
33. Verify that the calculated Second Harmonic Level is ≤ –56 dBc and record in the test records.
Use Table A-3.
