3-9 Amplitude Accuracy Spectrum Analyzer Performance Verification
3-26 PN: 10580-00303 Rev. D Model MS20xxB MM
8. On the power meter, press the Sensor key, the Cal Factor soft key, and then the Freq soft key. Use the
numeric keypad to enter the value matching the frequency of MS3692X as the input signal frequency. Do
this for both Sensor A and Sensor B. This sets the power meter to use the proper power sensor cal factor.
Press the System key to display the power reading.
9. Adjust the MG3692X output level so that Sensor A reading is –2 dBm ± 0.1 dB.
10. Record the Sensor B reading into the –2 dBm columns of the following tables in Appendix A.
• MS2034B – Table A-19, “Spectrum Analyzer Amplitude Accuracy Across Frequency Setup Table”
on page A-9
• MS2035B – Table A-44, “Spectrum Analyzer Amplitude Accuracy Across Frequency Setup Table”
on page A-22
11. Adjust the MG3692X output level so that Sensor A reading is –30 dBm ± 0.1 dB.
12. Record the Sensor B reading into the –30 dBm column of Table A-19 for MS2034B or Table A-36 for
MS2035B in Appendix A.
13. Repeat Step 7 through Step 12 for all the frequencies listed in Table A-19 for MS2034B or Table A-36 for
MS2035B in Appendix A.
Amplitude Across Frequency Measurements
14. Disconnect Sensor A from the 10 dB Fixed Attenuator and then install the 34NN50A Adapter to the end
of the attenuator.
Note
To maintain test setup integrity, do not disconnect Sensor B, the Power Splitter or the Fixed
Attenuator.
