Agilent 33220A/33250A Arbitrary Waveform
Generators
Quick Reference Guide
Main Controls
Selection of basic functions is through the
waveform buttons and softkey menu items below the
display. Once a main key and a softkey are
activated, you can enter numeric data on the
keypad concluded by units (e.g. Vpp) on the
softkey buttons. The display indicates which
softkey is active. Pressing that softkey again
switches to an alternate item (e.g. Period vs
Freq).

• Output When lit, the selected waveform is being
  output. Waveform can be toggled on and off using
  this button.
• Graph This button brings up an
  oscilloscope-type display with a summary of the
  waveform currently set up.
• Utility Provides access to the output impedance
  assumed by the instrument. See the third bullet
  in the overview section to the left for an
  important warning and additional info about this.
• Sine, Square, Ramp, Pulse These invoke the
  basic built-in waveforms and the softkeys which
  allow their parameters to be setup.
• Noise Turns waveform generator into a noise
  generator. Noise is flat from DC through the
  upper limit of the generator (20 MHz or 80 MHz
  depending on unit).
• Knob and arrow keys Provides the ability to
  change the active softkey numeric value via knob
  rotation. The arrow keys select which digit will
  be varied.

Overview

• These instruments are function generators with
  additional arbitrary waveform generation
  capabilities. The basic functions (waveforms)
  include random noise in addition to sinewaves,
  squarewaves, and pulse-trains.
• The primary difference between the two models is
  the frequency range. The 33220 generates
  waveforms and noise to 20 MHz, while the 33250
  works to 80 MHz and has improved edge speeds on
  squarewaves and pulsed waveforms.
• Note that both instruments assume a 50 Ohm load
  is attached unless the output is reconfigured
  through the Utility menu (see top unit in photo).
  This means that if you program the unit to
  output 5V, it will actually be outputting 10V
  into a high-Z load (if it is in its default 50
  Ohm output mode). Since this can be dangerous to
  equipment, it is important to understand and
  verify what load is assumed (use IO Config
  softkey under Utility button).
