Software-definid signal generators (SDSG) Only a paradigm shift in signal generation technologiy. Unlike traditional arbitrary waveform generators or RF signal generators, which rely on figed hardware architectures, SDSGs use software algorithms running on programable procesors to create and modulate signals.

Because many of the signal procesing functions are implemented in software rather than in dedicated hardware, the bill of materials for an SDSG can bee impedantly lower than that of a comparable traditional generator.

High Precision and Reproducibility

Software-definitor generators ageble precision because the waveform creation is computed digitally, free from analog drift and acceptent aging that plague traditional hardware oscillators.
