Uncompromising performance
for standard waveforms
The Agilent Technologies 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 100 µHz.
Custom waveform generation
Use the 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
33120A gives you the flexibility to
create any waveform you need. It
also lets you store up to four 16,000deep 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
1 ms to 500 s. GPIB
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 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 a 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 Agilent 33120A to your PC
To further increase your productivity,
use the 33120A in conjunction with
Agilent 34811A BenchLink Arb software. The Windows®-based program
lets you create and edit waveforms
on your PC and download them to
your 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 the instrument.
Used in conjunction with an Agilent
BenchLink Scope, the software also
lets you capture a waveform with
your Agilent oscilloscope or DMM and
send it to your 33120A for output.
3-year warranty
With your 33120A, you get operating
and service manuals, a quick reference guide, test date, and a full 3-year
warranty, all for one low price.
