Spectrum Analyzer Performance Verification 3-5 Single Side Band (SSB) Phase Noise
MS20xxC MM PN: 10580-00307 Rev. D 3-9
23. Enter 3 and then press the Enter key.
24. Wait until the Trace Count displays 3/3.
25. Press the Marker hard key and then the Peak Search soft key.
26. Press the Delta On/Off soft key to turn On the Delta Marker.
27. Enter 10 and press the kHz soft key to set Delta frequency to 10 kHz.
28. Record the Marker readout value into the Measured Value column of Table A-14, “Spectrum Analyzer
SSB Phase Noise” on page A-8 for MS2036C, of Table A-35, “Spectrum Analyzer SSB Phase Noise”
on page A-18 for MS2037C or of Table A-59, “Spectrum Analyzer SSB Phase Noise” on page A-31 for
MS2038C in Appendix A.
29. Subtract 30 dB from the Measured Value and record the result to the Calculated Value column of
Table A-14 for MS2036C, of Table A-35 for MS2037C or of Table A-59 for MS2038C in Appendix A.
Example equation:
–70 dBc measured –30 dB = –100 dBc/Hz
30. Verify that the calculated result is less than the specification for 10 kHz Offset.
31. Press the Marker hard key and then the Delta On/Off soft key to turn Off Delta Marker.
32. Press the Span hard key.
33. Enter 220 and then press the kHz soft key to set Span to 220 kHz.
34. Wait until the Trace Count displays 3/3.
35. Press the Marker hard key and then the Peak Search soft key.
36. Press the Delta On/Off soft key to turn On Delta Marker.
37. Enter 100 and press the kHz soft key to set Delta frequency to 100 kHz.
38. Record the Marker readout value into the Measured Value column of Table A-14, “Spectrum Analyzer
SSB Phase Noise” on page A-8 for MS2036C, of Table A-35, “Spectrum Analyzer SSB Phase Noise”
on page A-18
for MS2037C or of Table A-59, “Spectrum Analyzer SSB Phase Noise” on page A-31 for
MS2038C in Appendix A.
39. Subtract 30 dB from the Measured Value and record the result to the Calculated Value column of
Table A-14 for MS2036C, of Table A-35 for MS2037C or of Table A-59 for MS2038C in Appendix A.
40. Verify that the calculated result is less than the specification for 100 kHz Offset.
41. Press the Delta On/Off soft key to turn Off the Delta Marker.
42. Press the Span hard key.
43. Enter 2.2 and then press the MHz soft key to set Span to 2.2 MHz.
44. Wait until the Trace Count displays 3/3.
45. Press the Marker hard key and then the Peak Search soft key.
46. Press the Delta On/Off soft key to turn On Delta Marker.
47. Enter 1 and press the MHz soft key to set Delta frequency to 1 MHz.
48. Record the Marker readout value into the Measured Value column of Table A-14 for MS2036C, of
Table A-35 for MS2037C or of Table A-59 for MS2038C in Appendix A.
49. Subtract 30 dB from the Measured Value and record the result to the Calculated Value column of
Table A-14 for MS2036C, of Table A-35 for MS2037C or of Table A-59 for MS2038C in Appendix A.
50. Verify that the calculated result is less than the specification for 1 MHz Offset.
Note
After setting the new span, Trace Count continues to display 3/3 until a sweep is complete. Then it
starts to count from 1/3.
