AFG300 Series Delivers Five Functions in One Tool

Function Generator

The AFG300 Series is an excellent 16 MHz function generator with built-in arbitrary waveform, burst, sweep, and modulation capabilities. The instruments support standard waveforms including sine, square, triangle, ramp, pulse, DC and noise. Its sweep function includes Linear and Logarithmic (up or down) while operating in the Continuous, Triggered, and Burst modes.

Arbitrary Waveform Generation

With a sample rate of 16 MS/s, 12-Bit vertical resolution and a non-volatile memory that holds four 16,384-point waveforms, the AFG300 Series are powerful tools for simulating complex waveforms. Waveforms can be downloaded directly from selected Tektronix oscilloscopes and arbitrary waveform generators via GPIB, created with the standard ArbExpress™ waveform editing software package, or entered via the front panel.
