Spectrum Analyzer Performance Verification 3-7 Input Related Spurious (IRS) Signals
MS20xxC MM PN: 10580-00307 Rev. D 3-15
22. Wait until one sweep is completed.
23. Press the Marker hard key and then the Peak Search soft key.
24. Record the Marker amplitude reading for 1000 MHz into Table A-16, “Spectrum Analyzer Input Related
Spurious (IRS) Signals” on page A-8 for MS2036C, into Table A-37, “Spectrum Analyzer Input Related
Spurious (IRS) Signals” on page A-19 for MS2037C or into Table A-61, “Spectrum Analyzer Input
Related Spurious (IRS) Signals” on page A-32 for MS2038C.
25. Press the Freq hard key and then press the Start Freq soft key.
26. Enter 719 and press the MHz soft key to set Start Freq to 719 MHz.
27. Press the Stop Freq soft key.
28. Enter 721 and press the MHz soft key to set Stop Freq to 721 MHz.
29. Wait until one sweep is completed.
30. Press the Marker hard key and then the Peak Search soft key.
31. Record the Marker M1 amplitude reading into the Measured Value column for 719 MHz to 721 MHz in
Table A-16 for MS2036C, inTable A-37 for MS2037C or in Table A-61 for MS2038C.
32. Calculated the input related spurious level using the following formula:
Input Related Spurious dBc =
Marker M1 Amplitude Reading – Amplitude Reading of 1000 MHz
33. Record the calculated value into the Calculated IRS column for 719 MHz to 721 MHz in Table A-16 for
MS2036C, in Table A-37 for MS2037C or in Table A-61 for MS2038C and verify that it is ≤ –60 dBc.
3273 MHz Input Related Spurious Check
34. Set the MG3692X output to 3273 MHz CW, with an RF output level of –30 dBm.
35. On the MS203xC VNA Master, press the Freq hard key and then the Center Freq soft key.
36. Enter 3273 and then press the MHz soft key to set Center Freq to 3273 MHz.
37. Press the BW hard key and then the RBW soft key.
38. Enter 10 and then press the
kHz soft key to set RBW to 10 kHz.
39. Press the VBW soft key.
40. Enter 1 and then press the kHz soft key to set VBW to 1 kHz.
41. Press the Shift key and then press the Trace (5) key.
42. Press the Trace A Operations soft key and then the # of Averages soft key.
43. Enter 5 and then press the Enter key to set # of Averages to 5.
44. Wait until the Trace Count displays 5/5.
45. Press the Marker hard key and then the Peak Search soft key.
46. Record the Marker amplitude reading of 3273 MHz into Table A-16 for MS2036C, into Table A-37 for
MS2037C, or into Table A-61 for MS2038C.
47. Press the Freq hard key and then the Start Freq soft key.
48. Enter 2423 and the press the MHz soft key to set Start Freq to 2423 MHz.
49. Press the Stop Freq soft key.
50. Enter 3271 and press the MHz soft key to set Stop Freq to 3271 MHz.
51. Wait until Trace Count displays 5/5.
Note
After the new frequency range has been set, Trace Count continues to display 5/5 until a new sweep
is complete. Then it starts to count from 1/5.
