Spectrum Analyzer Verification 2-2 Single Side Band (SSB) Phase Noise Verification
S3xxE MM PN: 10580-00253 Rev. J 2-3
2-2 Single Side Band (SSB) Phase Noise Verification
This test is used to verify the single side band (SSB) phase noise 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
• Anritsu 15NN50-1.5C RF 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 1.00 GHz CW, with an RF output level of +0 dBm.
4. Connect the output of the MG3692X Synthesized Signal Source to the RF In connector of the Site Master.
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 press the Performance soft key.
9. Press the Amplitude soft key, then press the Reference Level soft key.
10. Use the keypad to enter 0 and press the dBm soft key.
11. Press the Atten Lvl soft key, use the keypad to enter 15 and press the dB soft key.
12. Press the Freq soft key and press the Center Freq soft key.
13. Use the keypad to enter 1.00 and press the GHz soft key.
14. Press the Span soft key, use the keypad to enter 110, and press the kHz soft key.
15. Press the BW soft key and press the RBW soft key.
16. Use the keypad to enter 1 and press the kHz soft key.
17. Press the VBW soft key and use the keypad to enter 3, then press the Hz soft key.
18. Press the Shift key and then press the Trace (5) key, then press the Trace A Operations soft key.
19. Press the # of Average soft key, use the keypad to enter 7, then press the Enter key.
20. Wait until the Trace Count displays “7/7”.
21. Press the Marker key and press the Peak Search soft key.
22. Press the Delta On/Off soft key to turn Delta On.
23. Use the keypad to enter 10 and press the kHz soft key.
24. Enter the measured value into Table A-2, “Spectrum Analyzer SSB Phase Noise Verification”.
25. Subtract 30 dB from the average value and verify that the result is less than –100 dBc/Hz
(for 10 kHz offset) or –105 dBc/Hz (for 100 kHz offset) or –115 dBc/Hz (for 1 MHz offset) and record the
Calculated Value results in the test records. Use Table A-2.
For example: –70 dBc measured – 30 dB = –100 dBc/Hz
26. Repeat Step 16 through Step 25 for 100 kHz (set Span to 220 kHz) and 1 MHz offset (set Span to
2.04 MHz. Enter the test results and calculations in the appropriate rows of Table A-2.
