2 Fluke 280 and 290 Series
The Fluke 280 Series and
290 Series Waveform
Generators combine a
true variable clock
arbitrary waveform
generator with a high
performance DDS func-
tion 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 chan-
nels 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.
Universal waveform generators offering
superior performance and excellent value
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 sophis-
ticated 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 inter-
faces (or memory card where
fitted).
Memory card storage
Fluke 290 Series units incorpo-
rate a CompactFlash memory
card, giving effectively unlim-
ited 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 architec-
ture 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 wave-
forms.
Wide range sweep
All waveforms can be swept
over their full fre quency range
at a rate variable between milli-
seconds 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 simulta-
neously.
