• MS2035B – Table A-40, “Spectrum Analyzer Input Related Spurious (IRS) Signals” on page A-19
33. Calculated the input related spurious level using the formula below:
Input Related Spurious dBc = Marker 1 Reading – Amplitude Reading of 2072.5 MHz
34. Record the calculated value into the Calculated IRS column for 1222.5 MHz to 2072 MHz in Table A-15
for MS2034B or Table A-40 for MS2035B in Appendix A and verify that it is <
–60 dBc.
35. Repeat Step 26 through Step 34 setting a start frequency of 2073 MHz and a stop frequency of
2922.5 MHz and record the results into the appropriate columns for 2073 MHz to 2922.5 MHz in
Table A-15 for MS2034B or Table A-40 for MS2035B in Appendix A.
