Agilent / HP 33120A Function Arbitrary Waveform Generator

Description

This 33120A generator has been in my lab storage over the last several years
, and is in excellent condition--see photos.  Scope photos are of this unit.  Fan is quiet, display is bright, virtually no dings or scratches.  I checked it out before listing it and it works great.  It comes with a 30 day return if not abused or opened.
Great for audio equipment evaluation:  Total Harmonic Distortion (THD) measures only 0.025%, 20 to 20 kHz on my Audio Precision.
This is an amazingly flexible function generator and AWG.  Many waveforms, noise and pulse types are already included.  Square waves have a fast risetime (about 22 nS), and are pretty square up to 5 MHz.
Manuals are available on the Keysight and other web locations.
Here's what Keysight says:
The 33120A function generator has a proven legacy, 15 MHz bandwidth, arbitrary waveforms & modulation capability. DDS technology provides precise adjustment and frequency stability.
15 MHz sine & square waveforms
Ramp, triangle, noise & DC waveforms
12-bit, 40 MSa/s, 16,000 points arbitrary waveforms
AM (int/ext), FM (int), FSK (internal/external), burst (int/extl)
Linear & logarithmic sweeps and burst operation
Uncompromising performance for standard waveforms
The Keysight Technologies, Inc. 33120A Function/Arbitrary Waveform Generator uses direct digital
-
synthesis techniques to create a stable, accurate
output signal for clean, low distortion sine waves. It also
gives you fast rise-
and fall
-
time square wave, and linear ramp waveforms down to 100 μHz.
Custom waveform generation
Use the 33120A to generate complex custom waveforms such as a heartbeat or t
he output of a
mechanical transducer. With 12-bit resolution, and a sampling rate of 40 MSa/s, the 33120A gives you
the flexibility to create any waveform you need. It also lets you store up to four 16,000-deep waveforms in
nonvolatile memory.
Easy-
to-use
functionality
Front
-panel operation of the 33120A is straightforward and intuitive. You can access any of ten major
functions with a single key press or two, then use a simple knob to adjust frequency, amplitude and offset.
To save time, you can enter voltage values directly in Vp-p, Vrms or dBm. Internal AM, FM, FSK and
burst modulation make it easy to modulate waveforms without the need for a separate modulation source.
Linear and log sweeps are also built in, with sweep rates selectable from 1ms to 500 s. GPIB and RS
-232
interfaces are both standard, plus you get full programmability using SCPI commands.
