3-16 PN: 10580-00307 Rev. D MS20xxC MM
52. Press the Marker hard key and then the Peak Search soft key.
53. Record the Marker M1 amplitude reading into the Measured Value column for 2423 MHz to 3271 MHz in
Table A-16 on page A-8 for MS2036C, in Table A-37 on page A-19 for MS2037C or in Table A-61
on page A-32 for MS2038C.
54. Calculated the input related spurious level using the following formula:
Input Related Spurious dBc =
Marker M1 Amplitude Reading – Amplitude Reading of 3273 MHz
55. Record the calculated value into the Calculated IRS column for 2423 MHz to 3271 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.
56. Press the Freq hard key and then the Start Freq soft key.
57. Enter 3275 and the press the MHz soft key to set Start Freq to 3275 MHz.
58. Press the Stop Freq soft key.
59. Enter 4123 and press the MHz soft key to set Stop Freq to 4123 MHz.
60. Wait until Trace Count displays 5/5.
61. Press the Marker soft key and then the Peak Search soft key.
62. Record the Marker M1 amplitude reading into the Measured Value column for 3275 MHz to 4123 MHz in
Table A-16 for MS2036C, in Table A-37 for MS2037C or in Table A-61 for MS2038C.
63. Calculated the input related spurious level using the following formula:
Input Related Spurious dBc =
Marker M1 Amplitude Reading – Amplitude Reading of 3273 MHz
64. Record the calculated value into the Calculated IRS column for 3275 MHz to 4123 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.
8000 MHz Input Related Spurious Check
65. Set the MG3692X output to 8000 MHz CW, with an RF output level of –30 dBm.
66. On the MS203xC VNA Master, press the Freq hard key and then the Center Freq soft key.
67. Enter 8000 and then press the MHz soft key to set Center Freq to 8000 MHz.
68. Press the BW hard key and then the RBW soft key.
69. Enter 1 and then press the kHz soft key to set RBW to 1 kHz.
70. Press the VBW soft key.
71. Enter 100 and then press the Hz soft key to set VBW to 100 Hz.
72. Wait until the Trace Count displays 5/5.
73. Press the Marker hard key and then the Peak Search soft key.
74. Record the Marker amplitude reading at 8000 MHz into Table A-16 for MS2036C, into Table A-37 for
MS2037C or into Table A-61 for MS2038C.
75. Press the Freq hard key and then the Start Freq soft key.
76. Enter 7719 and the press the MHz soft key to set Start Freq to 7719 MHz.
77. Press the Stop Freq soft key.
78. Enter 7721 and press the MHz soft key to set Stop Freq to 7721 MHz.
79. Wait until Trace Count displays 5/5.
80. Press the Marker hard key and then the Peak Search soft key.
81. Record the Marker M1 amplitude reading into the Measured Value column for 7719 MHz to 7721 MHz in
Table A-16 for MS2036C, in Table A-37 for MS2037C or in Table A-61 for MS2038C.
