Analog Function Generators
The function generator is a particularly versatile instrument. It can generate a variety of precision wave shapes
over a range of frequencies from mHz to MHz with a wide range of controlled amplitudes from a low-impedance
source, and maintain constant amplitude as the frequency is varied.
Although digital function generators may offer more features, analog function generators have advantages that
can make them more appropriate for certain applications.

Function generators fall into two basic categories,
analog and digital.
Analogue generators use a voltage controlled
oscillator to generate a triangular waveform of
variable frequency. Sinusoids and square waves are
generated from this.
Digital generators use a digital to analog converter
(DAC) to generate a wave shape from values stored
in memory. Normally such generators only offer
sine and square waves up to the maximum generator frequency. Triangle waves and other waveforms
are limited to a much lower frequency.
Analogue generators offer several advantages:
1. They provide simple and instantaneous manual
control of frequency and amplitude.
2. They do not have the high frequency limitations
for non-sinusoidal waveforms such as triangles and
ramps that digital generators do.
3. The starting price for an analog generator is
considerably lower than for a digital generator.

Generators 4.
Digital Function Generators
Digital function generators
can be divided into three
broad categories:
1. DDS* Function Generators
without Arbitrary - these
perform a similar function to
an analog function generator,
but with the advantages
of DDS based stability,
resolution, and sinewave
purity. The TG2000 falls into
this category.
2. DDS Function/Arbitrary
Generators - these have the
ability to produce arbitrary
waveforms in addition to
standard waveforms, but
within the limitation imposed
by using a DDS system. The
TG1010A and TG5011 fall
into this category.
3. Universal Arbitrary
Waveform Generators
- these combine a DDS
function generator with a
variable-clock* arbitrary
generator. Typically these
generators incorporate more
sophisticated systems for
the production of arbitrary
waveforms. The TGA1240
and TGA12100 series (see
page 17 ) fall into this
category. The TG4001 also
has a similar architecture.

7. Arbitrary Generators - waveform generation
Measurably better value
ARB generator types
Arbitrary generator describes a class of digital
generator potentially capable of reproducing any
waveform shape. There are two distinctly different
ways in which arbitrary waveforms can be produced
- DDS and Variable Clock *.
Because each manufacturer may choose a different
description for their product, it is not easy to know
which underlying technology is being used.
There are three broad classes of arbitrary waveform
generator:
1. Generators that use DDS (direct digital synthesis)
for the production of both standard waveforms
(function generator mode) and arbitrary waveforms.
These are most commonly described as either
Function/Arbitrary Generators or Arbitrary/Function
Generators (AFG).
2. Generators that use a variable clock architecture
for the production of both standard waveforms and
arbitrary waveforms. Within these generators a
standard waveform is simply a specific instance of
an arbitrary waveform.
These are most commonly described as Arbitrary
Waveform Generators (AWG)
3. Generators that use DDS for the production of
standard waveforms (function generator mode) and
variable clock for generating arbitrary waveforms.
These may be described as Universal Arbitrary
Waveform Generators or simply Arbitrary Waveform
Generators (AWG) as in category 2.
* See the TTi web site for more information about
arbitrary generator architectures.
TGA overview
TTi generators with the TGA prefix are universal
arbitrary waveform generators offering a choice
of one, two or four channels.
Two series are available; the TGA1240 which
has a maximum clock speed of 40MHz, and the
TGA12100 which has a maximum clock speed of
100MHz, greater waveform memory length, and
a number of additional features.
A key feature of both series is the universal
architecture which combines the advantages
of true variable clock arbitrary waveform
generation with the benefits of DDS (direct
digital synthesis) when acting as a function
generator.
The two and four channel models offer
exceptional flexibility with channels that can
be fully independent or linked. In independent
mode each channel is a completely separate
generator offering not just differing frequency,
amplitude and waveform but different
operational modes.
For example one channels could be used as a
function generator while another is used as
an arbitrary generator and a third as a pulse
generator.
The channels can be set to provide inter-channel
triggering, modulation or summing. Alternatively
they can be linked to offer multi-channel phase
controlled signals.

Arbitrary, function and pulse
Each channel of a TGA series generator can be used as an
arbitrary generator, function generator, or pulse pattern
generator.
As a pulse generator
a pattern of up to
ten pulses can be
defined with each
pulse having its own
amplitude, width and
delay. The complete
pattern can then be
replayed at a user
defined repetition
rate.
Multi-channel phase locking
Multi-channel TGA series generators can be used to
generate multi-phase signals
Any number of
channels can be phase
locked with offsets
defined to a resolution
of 0.1 degrees.
TGA12100 models can
also be phase locked
to an external clock
and provide phase
continuous frequency changes with a varying external
signal.
Waveform
sequencing
Multi-channel
modulation
Sequencing enables
complex waveforms
to be constructed by
sequencing simpler
elements.
Inter-channel
modulation and
summing allows the
creation of complex
modulation systems for
simulation and testing.
