Uncompromising performance for functions

and waveforms

The Agilent Technologies 33220A Function/Arbitrary

Waveform Generator uses direct digital synthesis

(DDS) techniques to create a stable, accurate

output signal for clean, low distortion sine waves.

It also gives you square waves with fast rise and fall

times up to 20 MHz and linear ramp waves up to

200 kHz.

Pulse generation

The 33220A can generate variable-edge-time pulses

up to 5 MHz. With variable period, pulse width, and

amplitude the 33220A is ideally suited to a wide

variety of applications requiring a flexible pulse signal.

Custom waveform generation

Use the 33220A to generate complex custom

waveforms. With 14-bit resolution, and a sampling

rate of 50 MSa/s, the 33220A gives you the flexibility

to create the waveforms you need. It also lets you

store up to four waveforms in nonvolatile memory.

The Agilent IntuiLink Arbitrary Waveform software

allows you to easily create, edit, and download

complex waveforms using the waveform editor.

Or you can capture a waveform using IntuiLink

for Oscilloscope and send it to the 33220A for

output. To find out more about IntuiLink, visit

www.agilent.com/find/intuilink.

Easy-to-use functionality

Front-panel operation of the 33220A is straight-

forward and user friendly. You can access all major

functions with a single key or two. The knob or

numeric keypad can be used to adjust frequency,

amplitude, offset, and other parameters. You can

even enter voltage values directly in Vpp, Vrms, dBm,

or as high and low levels. Timing parameters can be

entered in Hertz (Hz) or seconds.

Internal AM, FM, PM, FSK, and PWM modulation

make it easy to modulate waveforms without the

need for a separate modulation source. Linear and

logarithmic sweeps are also built in, with sweep

rates selectable from 1 ms to 500 s. Burst mode

operation allows for a user-selected number of

cycles per period of time. GPIB, LAN, and

USB interfaces are all standard, plus you get

full programmability using SCPI commands.

External frequency reference (Option 001)

The 33220A external frequency reference lets you

synchronize to an external 10 MHz clock, to another

33220A, or to an Agilent 33250A. Phase adjustments

can be made from the front panel or via a computer

interface, allowing precise phase calibration and

adjustment.
