Safety Summary

The following safety precautions apply to both operating and maintenance personnel

and must be observed during all phases of operation, service, and repair of this

instrument. Before applying power, follow the installation instructions and become

familiar with the operating instructions for this instrument.

If this device is damaged or something is missing, contact the place of purchase

immediately.

This manual contains information and warnings that must be followed to ensure safe

operation as well as maintain the meter in a safe condition.

GROUND THE INSTRUMENT

To minimize shock hazard, the instrument chassis and cabinet must be connected

to an electrical ground. This instrument is grounded through the ground conductor of

the supplied, three-conductor ac power cable. The power cable must be plugged into

an approved three-conductor electrical outlet. Do not alter the ground connection.

Without the protective ground connection, all accessible conductive parts (including

control knobs) can render an electric shock. The power jack and mating plug of the

power cable must meet IEC safety standards.

DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE

personnel. Disconnect the power cord before removing the instrument covers and

replacing components. Under certain conditions, even with the power cable removed,

dangerous voltages may exist. To avoid injuries, always disconnect power and

discharge circuits before touching them.

DO NOT SERVICE OR ADJUST ALONE

Do not attempt any internal service or adjustment unless another person, capable of

Introduction of SFG-20X Series

ThemanualcoversthefollowingtwotypesofSFG-20XSeriesFunction/Arbitrary

Waveform Generators: SFG-210 and SFG-205.

SFG-20X Series Function/Arbitrary Waveform Generators adopt the direct

digital synthesis (DDS) technology, which can provide stable, high-precision,

pure and low distortion signals. Its combination of excellent system features,

easinessinusageandversatilefunctionsmakesthisgeneratoraperfectsolution

for your job now and in the future.

SFG-20XSeriesFunction/ArbitraryWaveformGeneratorhasaclearandsimple

front-panel. The user-friendly panel layout and instructions, versatile terminals,

direct graph interface, built-in instructions and help system have greatly

simplified the operation process, with the help of which, users do not have to

spend a great deal of time learning and familiarizing the operation of the

generator before they can use it proficiently. The built-in AM, DSB-AM,FM, PM,

ASK, FSK and PWM modulation functions generate modulated waveforms at

ease, without the help of a separate modulating source. USB I/O is a standard

accessory, while GPIB is optional. Remote instructions meet the SCPI

specification requirements.
