... Complex Modulation for all AWGs
Open Environment
ArbIQ is an open environment. Users can choose among the built-in signal parameters or define their own. Signals characteristics as baseband filtering and payload data can be imported from externally defined files. Users can even create their own modulation schemes by editing their constellation diagrams and symbol mapping. Non-supported modulation schemes can also be accommodated through the external I-Q symbol/envelope feature.
User-Defined Features
Modulation Schemes
The modulation scheme edition tool allows users to define constellations with any geometry, with or without offset (Q delay) or rotation for each symbol.
Baseband Filtering
Defining user-defined filters is s easy as specifying the isolated pulse response. This strategy allows also to define any linear distortion.
Data
Any PRBS sequence and pattern can be selected. Patterns can accomodate random data so training sequences or frame synch sections can be defined.
I & Q Signals
Any I and Q signal can be defined in the time domain and imported by ArbIQ. Signal is then resampled and processed just as any internally created one.
