Entry-level signal generation often equals limited functionality and flexibility. The new AFG2021 arbitrary/function generator from Tektronix however changes that equation with features including 20 MHz bandwidth, 14-bit resolution, 250 MS/s sample rate and an intuitive user interface. A PC software tool lets users create and import waveforms into the instrument to meet custom stimulus requirements. A 3.5 inch color TFT screen shows relevant parameters in both graphic and text formats. The generator includes 12 standard waveforms, modulation capability, and a built-in noise generator to thoroughly exercise designs.


The generator is targeted at cost-sensitive education and manufacturing applications but also offers the versatility to meet many R&D requirements. As a result educators are no longer forced to choose a signal generator that can only be used in entry level classes. The AFG2021's performance supports development of advanced course material involving more complex concepts such as serial data streams and modulated waveforms.
