Sony Tektronix AFG2020 Arbitrary Function Generator 250MS/s 100MHz Option 02

Sony Tektronix AFG2020 Arbitrary Function Generator 250MS/s 100MHz Option 02

The Sony Tektronix AFG2020 is a DDS (Direct Digital Synthesis) Synthesized Arbitrary Function Generator capable of outputting standard waveforms, modulated signals, swept signals, and user-defined arbitrary waveforms. Equipped with a built-in high-resolution monitor and graphical user interface, it functions as a self-contained signal source for both benchtop lab use and system integration via GPIB. This unit is equipped with Option 02, which adds a fully independent second output channel.

Applications

The AFG2020 is a mid-1990s benchtop arbitrary function generator from the Sony/Tektronix joint venture, a collaboration that produced test and measurement instruments for the Japanese and international markets during roughly 1990–2000. DDS-based generators like this one were a significant step up from earlier analog generators, offering highly stable, low-distortion outputs with digital frequency resolution and the ability to download custom waveforms directly from a DSO — eliminating the need for a PC or controller in many bench setups. The AFG2020 is used in electronics development, component characterization, communications testing, and educational lab environments wherever a stable, programmable signal source with modulation and arbitrary waveform capability is needed. The built-in GPIB interface makes it well-suited for automated test systems running HP-IB or IEEE-488 instrument buses, a standard configuration in production test and R&D labs of its era that remains common in legacy ATE environments today. Option 02's dual independent channel capability extends its usefulness to phase-relationship testing, two-tone intermodulation measurements, and differential signal stimulus.
