FEATURES
APPLICATIONS
Direct Digital Synthesis Signal Generator
Stable Signal Source
Low Distortion
SFG-1000 Series, an economic function
generator with high accuracy and high stability
output, is designed based on the DDS (Direct
Digital Synthesis) technology embedded in a
large scale FPGA. The frequency range of
3MHz and the output waveform selection as
Sine, Square, Triangle and TTL of
adequately provide the fundamental
features to ensure high confidence for the test
results. The DDS technology at an affordable
price gives a high-value solution to the users
who need a signal source for accurate but
unsophisticated measurement applications.
The frequency drift and the amplitude
instability of conventional signal sources
are fatal uncertainties to the high-accuracy
measurements. employs PLL
(Phase-Locked Loop) circuitry to generate
a stable waveform at 20ppm accuracy &
stability covering the frequency range from
0.1Hz up to 3MHz. When is
utilized to conduct experiments in the
laboratory, it secures the signal source
reliability, which is beyond the reach of any
traditional signal generators.
To most of the test engineers, it is always
an annoyance trying to get rid of the ringing
coming from the signal source being used
to stimulate the DUT. The high precision
measurements need to employ a signal
source without the existence of harmonic
components, which adhere to the oscillator
of conventional signal generator circuit.

User-Friendly Human Interface
All-Around Functionality
The thoughtful human interface of
SFG-1000 Series gives users a friendly
operation environment. There is no need to go
through a long and tedious learning curve to
get used to the operations of the product. The
key operation functions and the output on/off
control are the advanced features that could
only be seen on the high-end devices. You
could enjoy all these conveniences at a very
affordable cost.
A signal output with selectable waveform
among Sine, Square and Triangle, and an
additional signal output at TTL level are
included in SFG-1000 Series. The output
control features include frequency adjustment,
+/-5V DC offset and 40dB attenuation. All the
fundamental features of a signal generator are
well equipped on SFG-1000 Series with high
accuracy and stability. Combining convenience,
accuracy and economic cost, SFG-1000 Series
3 represents the beauty of GW Instek's design.
SFG-1000 Series, built over a DDS platform,
generates the waveform through high-
performance DAC and high-speed
comparator to effectively avoid the
generation of harmonic components.
Utilizing direct digital synthesis technology,
SFG-1000 Series provides an output waveform
with 55dBc low distortion ranging from
2mVpp to 10Vpp output level. At the press
of a button, you get a stable and high purity
output signal from SFG-1000 Series right away.
