Product Description:
Unmatched performance, versatility, intuitive operation, and affordability make the AFG3000C Series of Function, Arbitrary Waveform, and Pulse Generators the most useful instruments in the industry.

Superior Performance and Versatility:
Users can choose from 12 different standard waveforms. Arbitrary waveforms can be generated up to 128 K in length at high sampling rates. On pulse waveforms, leading and trailing edge time can be set independently. External signals can be connected and added to the output signal. Dual-channel models can generate two identical or completely different signals. All instruments feature a highly stable time base with only±1 ppm drift per year.

Intuitive User Interface Shows More Information at a Single Glance:
Color TFT LCD screen on all models shows all relevant wave form parameters and graphical wave shape at a single glance. This gives full confidence in the signal settings and lets you focus on the task at hand.Shortcut keys provide direct access to frequently used functions and parameters. Others can be selected conveniently through clearly structured menus. This reduces the time needed for learning and relearning how to use the instrument. Look and feel are identical to the world's most popular TDS3000 Oscilloscopes.

Arb Express™ Software Included for Creating Waveforms with Ease:
With this PC software waveforms can be seamlessly imported from any Tektronix oscilloscope, or defined by standard functions, equation editor,and waveform math.

Direct Digital Synthesis Signal Generator
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 3 MHz and the output waveform selection as Sine, Square, Triangle and TTL of SFG-1000 Series 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.

Stable Signal Source
The frequency drift and the amplitude instability of conventional signal source sare fatal uncertainties to the high-accuracy measurements. employs PLL(Phase-Locked Loop) circuitry to generate a stable waveform at 20 ppm 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 sourcere liability, which is beyond the reach of any traditional signal generators.

Low Distortion
To most of the test engineers, it is always an annoyance trying to get rid of the ringing coming from the signal source being usedto 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.
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 55 dBc low distortion ranging from 2m Vpp to 10 Vpp output level. At the pressof a button, you get a stable and high purity output signal from SFG-1000 Series right away.

User-Friendly Human Interface
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. Thekey 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.

All-Around Functionality
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 40 dB 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 Series3 represents the beauty of GW Instek's design.
