AFG-3000 Arbitrary Function Generator

New Product Announcement

Good Will Instrument is announcing an Arbitrary Waveform and Digital-Synthesized Function Generator, AFG-3000 Series, to the market. This is the new generation of GW Instek digital function and arbitrary waveform generator, migrating from the technology of its popular product, SFG-830, into an advanced arena.

The AFG-3000 Series is designed for industrial, scientific research and educational applications. The series comes with a bandwidth of 80MHz for AFG-3081 and 50MHz for AFG-3051.

The AFG-3000 Series, featuring 200Msa/s sampling rate, 16 bit vertical resolution and 1M point waveform length, is a very useful and flexible signal source to meet diversified application needs in the market today.

The user-friendly operation, the On-Screen Help, and the multiple ways of arbitrary waveform editing make AFG-3000 just a plug-and-play equipment. The point by point waveform data entry or standard waveform clip piling through front panel operation, the CSV file waveform data download, the direct waveform reconstruction through DSO waveform data import, and the PC software edited waveform download are the 4 ways available for arbitrary waveform editing.

A 4.3-inch high resolution TFT LCD in the AFG-3000 front panel is used to display waveform and setting parameters.

The large and high-resolution screen is especially useful when the arbitrary waveform construction is done through front panel operation. The impedance of AFG-3000 can be selected between 50 Ohm and Hi-Z to ensure right impedance compatibility between AFG and DUT.

WIDE FREQUENCY RANGE FROM 1μHZ to 80/50MHz

The AFG-3000 Series Arbitrary Waveform/ Function Generator employs direct digital synthesis (DDS) technology to generate and output a variety of stable and precise waveforms. The frequency operates at up to 80MHz (AFG-3081) or 50MHz (AFG-3051), with a maximum resolution of 1μHz for the entire frequency range. The built-in standard waveforms include sine, square, triangle, ramp, pulse, noise and other types of waveforms.

The Finest 1μHz Resolution

MODULATION, SWEEP and BURST FUNCTIONS

The Modulation functions, including AM, FM, FSK and PWM, are provided to cover a broad range of market requirements. A dedicated terminal for the modulating signal output is available in the front panel for modulation monitoring or other control purposes. Either an internal signal or an external signal can be selected to perform modulation.

FSK is a frequency modulation scheme in which digital information is transmitted through signal frequency variation. The BFSK (binary FSK) modulation, using two frequencies to represent data 1 and 0 respectively, is commonly applied for Call ID and Remote Metering applications.

PWM is a digital modulation scheme that can be used to adjust the output power level by controlling the pulse width of the driving signal. The examples include the speed control of motor rotation and the luminance control of LED lighting instrument. Changing the pulse width of driving signal via PWM, the rotating speed of motor and the luminance of LED will change accordingly.

PWM to Control & Test the Motor Speed

The Sweep function supports three trigger modes: INT, EXT and manual, and two sweep modes: LOG and LIN. Each time a sweep signal is perceived, the function generator will start to sweep through the user-defined frequency range by the frequency variation of either Log curve or Linear curve.

The Burst function supports two modes, “Gate” and “N Cycle”. To run burst function, the burst repetitive rate has to be set first, then the time duration of each burst has to be defined under Gate mode, or the number of the waveform cycles in each burst has to be set under N Cycle mode.

Under both Gate mode and N Cycle mode, the burst waveform polarity and phase can be controlled.

The profile of arbitrary waveform is composed of a series of data. The frequency of arbitrary waveform is derived from sampling rate divided by the number of points constructing a complete waveform, i.e. frequency = sampling rate / the number of points in a waveform. Based on the above, the higher the sampling rate, the higher the arbitrary waveform frequency can be available. At a specific waveform frequency, AFG-3000 gives a 5ns horizontal resolution for the output waveform, better than that a low sampling rate unit can provide.

The 16 bit amplitude resolution can display smooth waveforms, while a lower bit resolution will display only jagged or less smooth waveforms. To generate the maximum level of 10V Ramp Waveform as an example, AFG-3000 with

16 bit D/A converter gives a 0.15mV resolution. Whilst a signal source with 12 bit D/A converter will give only a

2.4mV resolution. The advantage of 16 bit resolution is to provide straight line waveform with fine resolution.

However, the lower bit resolution can only provide a ladder shape waveform under the same output setting.

16 bit Allows Greater Details

OUTPUT FROM ANY SECTION OF 1M-POINT-LONG WAVEFORMS

The AFG-3000 Series provides 10 sets of memory for user save and recall applications. Each set of memory is able to store a set of front panel setting and a set of 1M-point arbitrary waveform data. With 1M long memory, AFG-3000 can store more complex waveforms consisted of more data.

Furthermore, any section of waveform within each 1M memory can be edited or output independently. This is a unique feature allowing users to do waveform storage and extraction with more flexibility, and at the same time giving users the maximum utilization of the overall memory capacity.

Arbitrary Editing / Output

EASY OPERATION AND FLEXIBLE ARBITRARY WAVEFORM EDITING

The AFG-3000 presents four methods of Arbitrary Waveforms generation, including direct front panel operation,

PC software editing and download, CSV file download, and GDS-2000 Series oscilloscope direct input.

Front Panel Operation

Everything from waveform editing, I/O configuring, to panel setting storage and recall, can be completed directly through front panel operation. The point by point waveform data entry and standard waveform clip piling are both feasible. Front panel operation allows users to edit arbitrary waveform, which is correspondingly updated on the screen. A feature of "What

You See is What You Get".

Panel Operation

CSV file uploading

AFG-3000 supports CSV file editing for arbitrary waveform generation. The CSV file can be created in many ways, including using EXCEL spreadsheet, PC client software, front panel editing or math computing software. The computing result of math software, Octave for example, can be saved into CSV file. Edited CSV file can be downloaded from either USB flash or PC to AFG-3000 for arbitrary waveform output.

Direct Waveform Reconstruction (DWR) Capability

The AFG-3000 can be directly connected to a GW Instek

GDS-2000 Series DSO with USB cable for waveform data download. Under "DSO Link" mode of AFG-3000, the DSO will transfer the captured waveform data from its memory to AFG-3000 for creating a correspondent waveform output.

From Math Computing Software, Program and Result in CSV File

Arbitrary Waveform Editing PC Software

A PC software for AFG-3000 waveform editing is supported. The software contains not only waveform drawing tools but also a wide variety of waveform editing functions, such as waveform arithmetic operations. The most commonly used waveforms, including Rayleigh, Gaussian, Normal Noise, Pseudo Ternary, Bipolar AMI,

Manchester, Differential Manchester, RS-232, and NRZ etc., are available in the library for user to tailor specific waveforms as needed.

AFG-3000 allows users to select the suitable impedance between 50 ohm and High-Z, ensuring right impedance compatibility between AFG-3000 and DUT.

The built-in On-Screen Help allows users to understand the AFG-3000 operations and the definition of each function key easily.
