87. Press the Marker main menu button and then Peak Search submenu button.
88. Record the Marker amplitude reading into the Measured Value column for 2821 MHz to 2823 MHz in
Table A-15 on page A-6 for MS2034B or Table A-40 on page A-19 for MS2035B in Appendix A.
89. Calculated the input related spurious level using the formula below:
Input Related Spurious dBc = Marker 1 Reading – Amplitude Reading of 1500 MHz
90. Record the calculated value into the Calculated IRS column for 2821 MHz to 2823 MHz in Table A-15 for
MS2034B or Table A-40 for MS2035B in Appendix A and verify that it is <
–52 dBc.
