Up for sale is a used HP/Agilent 8904A DC-600kHz Multifunction Synthesizer / Generator.

It has been tested and is in good working condiiton.

Original Manufacturer Description:

The Keysight 8904A multifunction synthesizer generates accurate sinewaves from 0 Hz to 600 kHz with 0.1 Hz resolution. The 8904A also has five other standard functions: square, triangle, ramp, from 0 Hz to 50 kHz plus dc, and Gaussian white noise. All waveform values in the 8904A are digitally calculated in real time by Keysight Technologies' Digital Waveform Synthesis IC yielding 12-bit digital accuracy. Full GPIB programmability is also included standard on the 8904A. Sine to 600 kHz, square, ramp, triangle to 50 kHz
