SAFETY INSTRUCTIONS
This chapter contains important safety instructions that
you must follow when operating SFG-1000 series and
when keeping it in storage. Read the following before any
operation to insure your safety and to keep the best
condition for SFG-1000 series.
Safety Symbols
These safety symbols may appear in this manual or on SFG-1000 series.
Warning: Identifies conditions or practices that could

result in injury or loss of life.
Caution: Identifies conditions or practices that could
result in damage to SFG-1000 series or to other
properties.
Attention Refer to the Manual
Earth (ground) Terminal
Safety Guidelines
General Guideline
CAUTION
• Do not place any heavy object on SFG-1000 series.
• Avoid severe impacts or handling that leads to damage.
• Do not discharge static electricity to SFG-1000 series.
• Use only mating connectors, for the terminals.
• Do not block or obstruct cooling vent opening.
• Do not perform measurements at power source and
building installation site (Note below).
• Do not disassemble SFG-1000 series unless you are
qualified as service personnel.

Safety Instructions
• Pollution degree 1: No pollution or only dry, non-conductive
pollution occurs. The pollution has no influence.
• Pollution degree 2: Normally only non-conductive pollution
occurs. Occasionally, however, a temporary conductivity caused
by condensation must be expected.
• Pollution degree 3: Conductive pollution occurs, or dry,
non-conductive pollution occurs which becomes conductive due
to condensation which is expected. In such conditions,
equipment is normally protected against exposure to direct
sunlight, precipitation, and full wind pressure, but neither
temperature nor humidity is controlled.
Storage
Environment
• Location: Indoor
• Relative Humidity: < 70%
• Temperature: −10°C to 70°C
Power cord for the United Kingdom
When using SFG-1000 series in the United Kingdom, make sure the power
cord meets the following safety instructions.
NOTE: This lead / appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with the following code:
Green/ Yellow: Earth
Blue: Neutral
Brown: Live (Phase)
As the colours of the wires in main leads may not correspond with the colours marking
identified in your plug/appliance, proceed as follows:
The wire which is coloured Green & Yellow must be connected to the Earth terminal
marked with the letter E or by the earth symbol or coloured Green or Green & Yellow.
The wire which is coloured Blue must be connected to the terminal which is marked with
the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the terminal marked with the
letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment or contact the supplier.
This cable/appliance should be protected by a suitably rated and approved HBC mains
fuse: refer to the rating information on the equipment and/or user instructions for details.
As a guide, cable of 0.75mm2 should be protected by a 3A or 5A fuse. Larger conductors
would normally require 13A types, depending on the connection method used.
Any moulded mains connector that requires removal /replacement must be destroyed by
removal of any fuse & fuse carrier and disposed of immediately, as a plug with bared wires
is hazardous if a engaged in live socket. Any re-wiring must be carried out in accordance
with the information detailed on this label.

Technical background
Traditional
function
generators
DDS
methodology
SFG-1000 series uses the latest Direct Digital Synthesis
(DDS) technology to generate stable, high resolution
output frequency. The DDS technology solves several
problems encountered in traditional function generators,
as follows.
Constant current circuit methodology
This analog function generating method uses a constant
current source circuit built with discrete components
such as capacitors and resistors. Temperature change
inside the generator greatly affects the components
characteristics which lead to output frequency change.
The results are poor accuracy and stability.
In DDS, the waveform data is contained in and
generated from a memory. A clock controls the counter
which points to the data address. The memory output is
converted into analog signal by a digital to analog
converter (DAC) followed by a low pass filter. The
resolution is expressed as fs/2k where fs is the frequency
and k is the control word, which contains more than
28bits. Because the frequency generation is referred to
clock signal, this achieves much higher frequency stability
and resolution than the traditional function generators.

converts the digital data into an analog waveform. The

●
How can I get out of TTL/−40dB mode?
●
The device accuracy does not match the specification.
●
What are these error messages?
I pressed the Power switch on the front panel but nothing happens.
Make sure the AC source voltage is set at the rating
±10%, 50/60Hz. For power up sequence, see page17.
Otherwise the internal fuse might be blown out. For fuse
replacement procedure, see page35.
TTL does not activate (pressed Shift + Wave key)
You need to turn On the output first. Press the Output
key, then press Shift+Wave. For details, see page25.
How can I get out of TTL/−40dB mode?
For TTL: press the Shift key, then the wave key. For
details, see page25.
For −40dB mode, press the Shift key, then 3. For details,
see page22.
The device accuracy does not match the specification.
Make sure the device is powered On for at least 30
minutes, within +18°C~+28°C. This is necessary to
stabilize the unit to match the specification.
What are these error messages?
Several messages appear when trying to set the frequency
in irregular ways. Page37 summarizes the messages.
If there is still a problem, please contact your local dealer or GWInstek at
www.gwinstek.com.tw / marketing@goodwill.com.tw.
