Uncompromising performance
for standard waveforms

The HP 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 rise­and fall-time square wave, and
linear ramp waveforms down to
10 mHz.

Custom waveform generation

Use the HP 33120A to generate
complex custom waveforms such
as a heartbeat or the output of a
mechanical transducer. With 12-bit
resolution, and a sampling rate of
40 MSa/s, the HP 33120A gives you
the flexibility to create any
waveform you need. It also lets
you store up to found 16,000-deep
waveforms in nonvolatile memory.

Easy-to-use functionality

Front-panel operation of the
HP 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 500s. HP-IB and RS-232
interfaces are both standard,
plus you get full programmability
using SCPI commands.

Optional phase-lock capability

The Option 001 phase lock/TCXO
timebase gives you the ability to
generate synchronized phase-offset
signals. An external clock
input/output lets you synchronize
with up to three other HP 33120As
or with an external 10-MHz clock.

Option 001 also gives you a
TCXO timebase for increased
frequency stability. With accuracy
of 4 ppm/yr, the TCXO timebase
make an HP 33120A ideal for
frequency calibrations and other
demanding applications.

With Option 001, new commands
let you perform phase changes on
the fly, via the front panel or from a
computer, allowing precise phase
calibration and adjustment.

Link the HP 33120A to your PC

To further increase your
productivity, use the HP 33120A in
conjunction with HP 34811A
BenchLink Arb software. The
Windows®-based program lets you
create and edit waveforms on your
PC and download them to your
HP 33120A with the click of a mouse.
Create complex waveforms in a
math or statistics program--or use
the freehand drawing tool--then pass
them into HP BenchLink Arb. Use in
conjunction with HP BenchLink
Scope, the software also lets you
capture a waveform with your HP
oscilloscope or DMM and send it to
your HP 33120A for output.

3-year warranty

With your HP 33120A, you get
operating and service manuals, a
quick reference guide, test date,
and a full 3-year warranty, all for
one low price.
