2-3 Single Side Band (SSB) Phase Noise Verification Spectrum Analyzer Verification
2-4 PN: 10580-00255 Rev. J MT8212E and MT8213E MM
2-3 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
MT821xE Cell 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 Cell Master.
5. Turn on the Cell 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 submenu key to reset to the default starting
conditions.
8. Press the Shift key, then the Sweep (3) key, then the Sweep Mode key, and then press the Performance
submenu key.
9. Press the Amplitude main menu key, then press the Reference Level submenu key.
10. Use the keypad to enter 0 and press the dBm submenu key.
11. Press the Atten Lvl submenu key, use the keypad to enter 15, and press the dB submenu key.
12. Press the Freq main menu key and press the Center Freq submenu key.
13. Use the keypad to enter 1.00 and press the GHz submenu key.
14.
Press the Span submenu key, use the keypad to enter 110, and press the kHz submenu key.
15. Press the BW submenu key and press the RBW submenu key.
16. Use the keypad to enter 1 and press the kHz submenu key.
17. Press the VBW submenu key and use the keypad to enter 3, then press the Hz submenu key.
18. Press the Shift key and then press the Trace (5) key. Then press the Trace A Operations submenu key.
19. Press the # of Averages submenu 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 submenu key.
22. Press the Delta On/Off submenu key to turn Delta On.
23. Use the keypad to enter 10 and press the kHz submenu key.
24. Enter the measured value in Table A-2, “Spectrum Analyzer SSB Phase Noise Verification” on page A-2.
25. Subtract 30 dB from the average value and verify that the result is less than –100 dBc/Hz
(for 10 kHz offset) or less than –105 dBc/Hz (for 100 kHz offset) or less than –115 dBc/Hz (for 1 MHz
offset), and record the Calculated Value results in Table A-2.
For example: –70 dBc measured – 30 dB = –100 dBc/Hz
