SPURPLOT

This graphical analysis software enhances the quality of system designs. SPURPLOT helps in the process of selecting a frequency plan, mixer and filter criteria necessary for frequency translation. It allows for the tuning of these parameters according to particular frequency specifications. New features for Version 2.0 include: dual-conversion analysis with an added second mixer output tunable filter; improved interface with Windows 95 and NT; independent mixer intermodulation tables with editable LO power; and input power and conversion loss parameters added to each mixer. Spurious analysis graphs display the reference power levels and mixer tables for harmonic numbers have been increased to 15 X 15, allowing the user to select the size of the table used for calculations and copy from 5 X 5 to 15 X 15 in any combination.
