3-7 Input Related Spurious (IRS) Signals Spectrum Analyzer Performance Verification
3-18 PN: 10580-00307 Rev. D MS20xxC MM
111. Record the Marker M1 amplitude reading into the Measured Value column for 14719 MHz to 14721 MHz
in Table A-61.
112. Calculated the input related spurious level using the following formula:
Input Related Spurious dBc =
Marker M1 Amplitude Reading – Amplitude Reading of 15000 MHz
113. Record the calculated value into the Calculated IRS column for 14719 MHz to 14721 MHz in Table A-61
and verify that it is ≤ –60 dBc.
