The Keysight (formerly Agilent / HP) 33250A is a high-performance 80 MHz function and arbitrary waveform generator. It offers standard waveforms, pulse generation with variable edge times, and arbitrary waveforms powered by a 12-bit, 200 MSa/s architecture with 64 Kpoints of memory. It includes built-in AM, FM, and FSK modulation, linear/logarithmic sweep, and burst operation.
