HP / Agilent 33250A Function / Arbitrary Waveform Generator, 80 MHz

The HP/Agilent 33250A is an 80 MHz Function/Arbitrary Waveform Generator delivering direct digital synthesis with 1 µHz frequency resolution and exceptional signal purity. This instrument generates standard waveforms - sine, square, ramp, triangle, sin(x)/x, noise, and DC - across its full bandwidth, with pulse outputs up to 50 MHz featuring sub-8 ns rise/fall times. Arbitrary waveform generation operates at 200 MSa/s with 12-bit vertical resolution and 64K-point memory depth; up to four arbitrary waveforms can be stored in non-volatile memory with user-defined names.
