The Marconi 2026 is a multiple source generator which offers two RF signal generators in one box with a third source available as an option. Each source is a fully functional RF signal generator with AM, FM, 2FSK, 4FSK and pulse modulation capability. The 2026 is ideal for use in R&D and manufacturing where there is a need for two or three combined sources for conducting tests such as intermodulation and selectivity performance of components on receiver assemblies.
