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 pos-
sible 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. Param-
eters 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 genera-
tors can be phase locked.
290 Series models can be phase
locked to an external clock and
offer phase continuous
fre quency changes.
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 modu-
lation 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.
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.
Full waveform building tools includ-
ing standard waveforms, mathemati cal
expressions, and freehand drawing

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.
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.
