Introduction
Overview
This manual describes the features and operation of t
he Fluke models 281, 282 and 284
single-, two- and four-channel arbitrary waveform generators.
The physical differences between the two and four-channel generators are
straightforward: the two-channel instru
ment has no set-up keys or output connections for
channels three and four.
The single-channel instrument has essentially the sa
me keys but they are arranged quite
differently to suit the half-rack case. There are drawings of all three models at the end of
this manual.
The set-up and operation of an individual channel in any of the instruments is identical
and therefore no distinction is
made between the different models when describing the
functions associated with any single channel.
Those features associated with multi-channel operation (inter-channel summing, phase-
locking, etc.)
self-evidently apply only to the multi-channel instruments; the relevant
chapters are mostly grouped together towards the end of the manual (but before Remote
Operation) although some mention of multi-channel operation is made when appropriate
in earlier sections. To avoid repetition specific reference is not always made to two- and
four-channel instruments in the text; it is obvious when the description applies only to a
multi-channel instrument.
Features
These synthesized programmable arbitrary waveform generators have the following
features:
• 1, 2
or 4 independent 'arb' channels
• Sam
pling frequency up to 40 MHz
• Sine waves and square waves up to
16 MHz
• 12-bit vertical
resolution
• 64K poi
nts horizontal resolution per channel
• 256K point non-volatile waveform
memory
• Waveform
linking, looping and sequencing
• Inter-channel triggering, summing,
modulation and phase control
• GPIB and RS232 i
nterfaces
A combination of direct digital synthesis and phase lock loop techniques provides high
performance
and extensive facilities in compact instruments. These instruments can
generate a wide variety of waveforms between 0.1 mHz and 16 MHz with high resolution
and accuracy.
You can define arbitrary waveforms with 12 bit vert
ical resolution and from 4 to 65,536
horizontal points. In addition a number of standard waveforms are available including
sine, square, triangle, ramp and pulse.
You can replay arbitrary waveforms at a user specified waveform
frequency or period, or
you can define the sample rate in terms of period or frequency.
The instruments provide extensive waveform editing features bet
ween defined start and
end points, including waveform insert, point edit, line draw, amplitude adjust and invert.
