2-3 Spurious Response (Second Harmonic Distortion) Verification
The following test is used to verify the input related spurious response of the spectrum analyzer in the S332E
and S362E Site Master.
Equipment Required
• Anritsu MG3692X Synthesized Signal Source
• 10 MHz Reference Standard
• Anritsu 34RKNF50 50 ohm Adapter or equivalent
• Anritsu 15NN50-1.5C RF Coaxial Cable
• Anritsu 1030-96 50 MHz Low Pass Filter
• BNC male to BNC male Coaxial Cable
Procedure
1. Connect the 10 MHz reference source to the Anritsu MG3692X Synthesized Signal Source.
2. Turn on the 10 MHz reference source and the Anritsu MG3692X Synthesized Signal Source.
3. Set the MG3692X output to 50.1 MHz CW, with an RF Output Level of –30 dBm.
4. Connect one end of the 50 MHz Low Pass Filter to the output of the source and the other end to the
Site Master RF In with the coaxial cable.
5. Turn on the Site Master.
6. Press the Shift key and then the Mode (9) key. Rotate the knob to highlight Spectrum Analyzer and then
press the Enter key to switch to Spectrum Analyzer mode.
7. Press the Shift key, the Preset (1) key, and then the Preset soft key to reset to the default starting
conditions.
8. Press the Shift key, the Sweep (3) key, then the Sweep Mode soft key, and select the Performance soft
key.
9. Press the Amplitude soft key and then press the Reference Level soft key.
10. Use the keypad to enter –27 and press the dBm soft key.
11. Press the Atten Lvl soft key and enter 0, then press the dB soft key.
12. Press the Freq soft key and select the Center Freq soft key.
13. Use the keypad to enter 50.1
and press the MHz soft key.
14. Press the Span soft key, use the keypad to enter 100, and select the kHz soft key.
15. Press the BW soft key and select the RBW soft key.
16. Use the keypad to enter 1 and select the kHz soft key.
17. Press the VBW soft key. Use the keypad to enter 10 and then select the Hz soft key.
18. Press the Amplitude soft key.
19. Press the Detection soft key, and then the Peak soft key.
20. Press the Shift key and then press the Trace (5) key, then press the Trace A Operations soft key.
21. Press the # of Average soft key, use the keypad to enter 5 and then press the Enter key.
22. Wait until the Trace Count displays “5/5”.
23. Press the Marker key and press the Peak Search soft key.
24. Record the amplitude for 50.1 MHz. Use Table A-3, “Spectrum Analyzer Spurious Response (Second
Harmonic Distortion)”.
