2 Fluke 280 and 290 Series
Universal waveform generators offering
superior performance and excellent value
Pulse generator
Waveform sequencing
The Fluke 280 Series and
290 Series Waveform
Generators combine a
true variable clock
arbitrary waveform
generator with a high
performance DDS function generator and pulse
generator in a single
instrument.
Wide model range
The Fluke 280 Series and
290 Series comprise of six models:
• 281 40 MS/s single-channel
waveform generator in 3U half
rack size case.
• 282 40 MS/s two-channel
waveform generator in 3U case.
• 284 40 MS/s four-channel
waveform generator in 3U case.
• 291 100 MS/s single-channel
waveform generator in 3U half
rack size case.
• 292 100 MS/s two-channel
waveform generator in 3U case.
• 294 100 MS/s four-channel
waveform generator in 3U case.
On multi-channel units, each
channel can be operated fully
independently, or multiple channels can be linked using simple
or complex relationships.
A true arbitrary generator
The 280 and 290 Series are
highly sophisticated 12-bit
arbitrary waveform generators
capable of recreating virtually
any waveform. True variable
clock architecture is used with
clock speeds between 0.1 Hz and
100 MHz (40 MHz on 280 Series
units). This architecture avoids
the clock jitter associated with
DDS arbitrary generators and
permits waveform linking,
looping and sequencing.
Waveforms may be defined
with up to 4096 vertical points
and from 8 M to 1 M horizontal
points (4 K to 64 K points on
280 Series units).
Arbitrary waveforms may be
replayed at a specified waveform
frequency, period or sample clock
rate. An external sample clock
can also be used on 290 Series
units allowing seamless on the
fly changes to output frequency.
The 290 series waveform
storage is on removable Compact
Flash cards, making waveform
management easy and effectively
unlimited.
Function generator
Each channel can operate as a
full DDS function generator. High
quality sine, cosine, haversine,
havercosine and square waves
are available between 1 mHz and
16 MHz (280 Series) or up to 50
MHz (290 Series). Triangle, ramp
and sine(x)/x waveforms are
available from 0.1 mHz up to
500 kHz.
Pulse generator
Each channel can generate not
just pulses, but also complex
pulse trains. A pattern of up to
10 pulses can be quickly defined,
with each pulse having its own
amplitude, width and delay.
The whole pulse train pattern
can then be replayed at a user
defined repetition rate. Where
variable rise time pulses are
required, the full arbitrary
function can be used.

Waveform creation
and editing
Waveform creation and editing
features are in corporated within
the instrument. These in clude
waveform insert, point edit,
line draw, amplitude adjust and
invert.
A wide range of standard
waveforms are avail able for
insertion within an arbitrary
waveform. Sections of existing
arbitrary waveforms can also
be inserted. For more sophisticated waveform creation and
editing, Waveform Manager
Plus soft ware for the Windows®
operating system is provided.
Waveforms created on a PC
can be down loaded to the
instrument via the digital interfaces (or memory card where
fitted).
Memory card storage
Fluke 290 Series units incorporate a CompactFlash memory
card, giving effectively unlimited stor age for waveforms and
setups. Waveform data can be
transferred directly from a PC to
the memory card using the USB
card reader/writer supplied.
GPIB, RS-232, USB
The 280 and 290 Series
incorporate both RS-232 and
GPIB (IEEE-488) interfaces as
standard. 290 Series units also
have a USB interface. These can
be used for loading arbitrary
wave forms and for remote
control of all the instru ment
functions.
Waveform sequencing
The variable clock architecture of the 280 and 290 Series
enables waveforms to be
se quenced. Up to 1024 arbitrary
waveforms may be linked in a
sequence (16 waveforms on 280
Series). Each waveform can have
a loop count of up to 32,768 and
the whole sequence can be run
contin uously or re peated more
than a million times.
For multi-channel models,
waveforms on dif ferent channels
can be ‘daisy chained’ and
looped. By summing the channel
outputs, multiple segments from
multiple channels can be used
to create highly complex waveforms.
Wide range sweep
All waveforms can be swept
over their full fre quency range
at a rate variable between milliseconds and minutes. Sweep
can be linear or logarithmic,
single or continuous. Single
sweeps can be triggered from
the front panel, the trigger input,
or the digital interfaces. Multiple
channels can be swept simultaneously.
4 Fluke 280 and 290 Series
Waveform Manager Plus software
Amplitude modulation
Amplitude modulation and
suppressed car rier modulation
are available for all waveforms.
Any channel can be used to
modu late another chan nel.
Alternatively, all channels can
be modulated simul taneously via
the modulation input.
Built-in trigger generator
All waveforms are available as
a triggered burst whereby each
trigger edge will produce one
burst of the carrier. Start and
stop phase is fully variable. Both
triggered and gated modes can
be op erated from the internal
trigger generator, from an
adjacent channel, an external
source or a key press or remote
command. The trigger generator
signal is available as a separate
output if required.
Tone switching
The Fluke 280 and 290 Series
can provide triggered switching
between up to 16 frequencies of
standard or arbitrary waveforms.
Tone switching modes can be
gated, triggered or FSK using
any trig ger source. By summing
two channels together, it is possible to generate precise DTMF
test signals.
Fast and easy to use
All of the main information is
clearly displayed on a backlit
80 character LCD. Eight soft keys
enable fast data editing. Parameters can be entered directly
from the nu meric keypad or
changed with the spin wheel.
On the 2 and 4 channel models,
a Copy Chan nel key enables
similar setups to be created
across multiple channels with
ease.
Multi-channel phase
locking
Any number of channels can
be phase locked with offsets
defined to a resolution of
0.1° (or 360°/waveform points
for arbitrary wave forms). For
applications requiring more than
four channels, multiple generators can be phase locked.
290 Series models can be phase
locked to an external clock and
offer phase continuous
fre quency changes.
All models, including the
281 and 291, have the facility
for phase synchonising to
another similar generator.
Multi-channel summing
Waveform summing sums the
waveform from any channel into
the next channel. Alternatively
any number of chan nels can
be summed with an external
signal. This permits com plex
modulations, such as noise
superim position, to be created.
Inter-channel triggering
and modulation
Because any channel can be
triggered by the previous or next
channel, waveforms on differ ent
channels can be “daisy chained”
and looped. By summing the
channel outputs, many segments
from different channels can
be used to generate the final
waveform. A channel can be
used to AM modulate or SCM
modulate another channel.
Digital modulation
Inter-channel modulation and
summing allows the simulation
of various telecom digital modulation systems.

Waveform building tools
Toolkit
Waveforms can be built in any number
of sec tions using any combination of
the following: standard waveforms,
mathematical expressions, drawn
waveforms, uploaded waveforms,
im ported waveforms (using clipboard),
existing stored waveforms.
Waveform section limits can be defined
via move able cursors, which can be
dragged or positioned numeri cally.
Standard waveforms
The following waveforms are available
directly from the Waveforms dialogue
box: Sine, square, triangle, pulse, ramp,
sinc [sin(x)/x], gaussian, exponent, noise.
The mathematical expression for any
standard waveform can be examined by
opening the expression editor window.
Expression editor functions
The following mathematical operators
are available within the expression
editor: add, subtract, multiply, divide, xn,
sin, cos, arcsin, arccos, abs, log10, loge,
en, square root, floor, ceiling, random,
pulse, in conjunction with constants and
waveforms.
The expressions used for each section
of a waveform are retained and can be
displayed in a drop-down window.
Expression libraries
The mathematical expressions used
for wave form creation can be stored in
libraries. A de fault library is created for
each project that includes a number of
useful examples, including waveshapes
and modulations.
Waveform drawing
functions
Waveforms can be created or edited
using free hand drawing and/or
point-to-point line drawing.
Smoothing
Waveforms can be smoothed using a
running average filter. Start and end
points can be spec ified as well as the
number of points to average.
