Hp / Agilent 33250A The HP 33250A is an 80 MHz Function

The HP 33250A is an 80 MHz Function / Arbitrary Waveform Generator offers a full set of functions as well as versatile waveforms, with 12 bit resolution and a 200 MS/s sampling rate. In addition, the 33250A can generate waveforms up to 50 MHz with variable edge time. Built-in modulation capabilities (AM, FM, FSK, burst - all internal & external) and both linear and log sweeps further expand your test possibilities without requiring additonal generators. Plus, the external clock reference timebase increases the frequency stability while letting you generate precise phase-offset signals, phase-lock to another 33250A or to a 10 MHz frequency standard
