The VIAVI Solutions 3025 Digital RF Signal Generator is a 3U PXI modular instrument engineered for automated RF test systems in development and manufacturing environments. Originally designed by Aeroflex and later produced by Cobham, the 3025 generates complex RF signals across a wide frequency spectrum and integrates with Aeroflex PXI RF synthesizer modules to deliver complete signal generation solutions for wireless communications, broadcasting, and military applications.
