AFG-2100/2000 Series Arbitrary Function Generator
New Product Announcement
The AFG-2100/2000 Series Arbitrary Function Generator
The AFG-2100/2000 Series Arbitrary Function Generator is a DDS (Direct Digital Synthesized) based signal
generator designed to accommodate the Educational and Basic Industrial requirements for an accurate and
affordable signal source covering the output of Sine, Square (Pulse), Ramp (Triangle), Noise and Arbitrary
waveforms. The 20M Sa/s sampling rate, 10 bit vertical resolution and 4k point memory of the AFG-2100/2000
Series provide user with a flexible environment for creating the specific waveform output as needed. The
0.1Hz resolution of Sine, Square and Triangle waveforms and the 1% ~ 99% adjustable duty cycle of Square
(Pulse) waveform are the remarkable features to greatly extend its application range in various fields.
The AFG-2100/2000 Series includes 6 models in three frequency bands of 5MHz, 12MHz and 25MHz.
Besides the basic features of the whole AFG2100/2000 Series, AFG-2100 also carries additional features
of AM/FM/FSK Modulation, Sweep, and Frequency Counter.
The friendly human interface of AFG-2100/2000 Series allows user to set waveform parameters, including
waveform type, frequency, amplitude, DC offset, modulation type, and duty cycle, through keypad entry and/or
the knob selection, and display the set parameters on the 3.5” LCD screen. The AFG-2100/2000 Series is
equipped with a USB Device interface for remote control and waveform editing through a PC. A waveform
editing software is provided to facilitate the waveform creation on the PC. After the waveform editing is done,
the user is able to download the waveform data from PC to the AFG-2100/2000 Series for signal output.

Arbitrary Waveform Function
Other than the high accuracy and high stability DDS Function Waveforms-Sine, Square and Triangle, the
AFG-2100/2000 Series also provides the feature to generate Arbitrary Waveforms as what user wants. The
20MS/sa sampling rate, 10 bit vertical resolution and 4k point waveform memory allow user to create the
needed waveform point by point through keypad entry on the front panel, or to do waveform editing on the
PC and download the waveform data to the AFG-2100/2000 Series, for arbitrary waveform output. A C

software is available to facilitate the editing of complicated and irregular waveforms, which fulfill the
requirements of various applications in the real life scenarios.
Adjustable Duty Cycle
The adjustable duty cycle of square waveform is a commonly used feature of a Function Generator. For a
conventional Function Generator, however, the adjustable duty cycle mostly falls in a limited 20% ~ 80%
range, which may not fit the demands of specific applications. The AFG-2100/2000 Series is able to
provide a 1% ~ 99% variable duty cycle for its square waveform output. This feature allows the
AFG-2100/2000 Series to be used as a Pulse Generator to create pulse waveform simulating a spike
signal or a transient signal in most of the generic applications.
Parameter Setting
The keypad entry and/or knob selection for waveform parameter setting is a unique feature of the
AFG-2100/2000 Series. The conventional analog knob, which is commonly adopted in the AFG design, is not
accurate enough for precision setting of waveform parameters, and may generate noise to interfere the system
operation. The keypad entry design of AFG-2100/2000 Series improves the setting uncertainty of conventional
Function Generator and therefore significantly increases the accuracy of its
waveform output. Besides keypad entry, the AFG-2100/2000 Series also offers the knob selection convenience
with a digital knob design, which allows user to see the parameter value change in detail on the 3.5” LCD
screen when the adjustment is in progress.

Waveform Amplitude & DC Offset
Besides output waveform frequency, the AFG-2100/2000 Series is able to show output waveform
amplitude, DC offset and other key setting information on the LCD screen simultaneously. This provides
the convenience for user to know what signal is being sent out at the output terminal without the need to
check the waveform through an oscilloscope. Further more, the waveform amplitude value can be shown
in one of the three units, including Vpp, Vrms and dBm, depending on user’s selection. This saves time for
tedious math conversion among various units of waveform amplitude.
AM/FM/FSK Modulation, Sweep & Frequency Counter
All AFG-2100 models are equipped with additional AM/FM/FSK Modulation, Sweep & Frequency Counter
functions. The AM/FM modulated signal provides a means for basic modulation circuit tests and experiments.
Whereas, the FSK modulated signal is offered as a convenient source for the performance evaluation of
digital modulation circuits. The Sweep function, with accurate frequency sweep range & sweep time,
adequately fits a lot of basic applications in the market, such as sweep-tone test of the speaker in a 20Hz ~
20kHz sweep range. The built-in frequency counter of AFG-2100 is able to measure the frequency of an
external signal up to 150MHz. This add-on value saves for user an additional cost of purchasing a
standalone frequency counter.
USB Interface
The AFG-2100/2000 Series provides a USB Device Interface, which allows the programming of remote
control or ATE of the product. An arbitrary waveform editing software is available to facilitate the waveform

creation task. After the waveform editing is completed on the PC, the waveform data can be downloaded
through USB Interface to the AFG-2100/200 for arbitrary waveform output.
Arbitrary Waveform Editing PC Software
The arbitrary waveform editing software contains not only waveform drawing tools but also a wide variety of
waveform editing functions. 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. Besides, this software can import
CVI format file as waveform data which is created by the other tools. The editing software will stretch
AFG2100/2000 to more applications.

1.
AFG-2100/2000 Series is the clear price leader in the low cost Arbitrary Function Generator market
today. There are many low cost function generators, either analog or digital function generators,
available in the market, however, only AFG-2100/2000 Series has the “Arbitrary Waveform” feature
in this price range.
2.
The numeric keypad operation, the all-parameters display on LCD panel, the USB Interface, and the
waveform editing software support make AFG-2100/2000 the highest value product in the low cost
AFG market.
3.
The AFG-2100/2000 Series is not only suitable for Educational applications. With good features of
Arbitrary Waveform, 1% ~ 99% adjustable duty cycle for Square Waveform, and the programmability
through USB Interface, the AFG-2100/2000 Series is also suitable for the basic Industrial
applications.
4.
The AFG-2100/2000 Series, with far better features and same price level as SFG-2100/2000, will
fully replace the existing SFG-2100/2000 Series in the future.
