The Keysight/Agilent/HP 33250A is an 80 MHz function and arbitrary waveform generator employing Direct Digital Synthesis (DDS) technology to deliver stable, accurate waveforms for benchtop and automated test environments. It generates standard waveforms—sine, square, ramp, pulse, noise, DC, and Sin(x)/x—plus arbitrary waveforms with 12-bit vertical resolution, 200 MSa/s sample rate, and 64K memory depth. Four arbitrary waveforms can be stored in non-volatile memory with user-defined names for rapid recall.
