This product note explains using the DDS mode of Spectrum Instrumentation AWGs in detail. The product note explains the usage in a generic way and can be used for any Spectrum Instrumentation AWG product that has a DDS mode implemented or available as an option. All examples are done for the M4i.66xx AWG series but will also work with other models.
