Equivalent Dual-Channel Provides Augmented Value for Customers
GW Instek is launching AFG-2225, its first basic level dual-channel arbitrary function generator, which
provides superior features in its class. Both channels are equipped with same characteristics to fit dualsignal applications such as differential or IQ signaling. The outstanding cost-performance value makes
the AFG-2225 a practical instrument to accelerate the development process.
1% ~ 99% Adjustable Duty Cycle for
Square Waveform
Friendly User Interface for Easy
Parameter Setting and Parameters Display
The major features for both channels include 10Vpp output amplitude; 25MHz frequency bandwidth with
1uHz resolution; built-in waveforms of Sine, Square, Ramp (Triangle) and Noise. As to the 1%~99%
adjustable duty cycle of Square waveform can be used as pulse signal sources. For the arbitrary waveform,
user can edit the 66 built-in waveforms or create a whole new one. Moreover, AFG-2225 carries features
of AM/FM/PM/FSK/SUM Modulation, Sweep, Burst and Frequency Counter, which can be applied to
various communication fields.
Multiple Editing Methods to Edit
Arbitrary Waveform Easily
In addition to the intuitive and friendly user interface, the 3.5-inch color LCD displays the comprehensive
operation information including the true waveform presented at the output. USB Host and Device
interfaces are equipped to link the AFG-2225 with other devices, which provide the flexibility of waveform
generation for more practical usages. With link to GW Instek GDS-series Digital Storage Oscilloscopes
(DSOs), the waveforms of interest can be captured and reconstructed. User can also use the arbitrary
waveform PC software to edit the waveform and then send to AFG-2225 directly, or save the waveform
into flash drive and then transfer to AFG-2225.

Full-Functions equipped Dual-channel Signal Output Capability
In most two-channel signals applications, such as digital modulation and vehicle electronic simulation
signals, the similar or identical waveform capabilities are required for both channel outputs. Unlike other
dual-channel AFG in this class, AFG-2225 is fully equipped with equal capabilities on dual outputs. Most
of dual-channel arbitrary waveform generators in this basic level cluster offer one major channel and one
minor channel, in which the minor channel only provides less functions or inferior performances. This
sort of non-full-function dual-channel AFGs can not meet the requirements of reality.
Correlated Functions of Dual-channel Outputs
The two channels can be used in either independent or correlated configuration. AFG-2225 provides three
correlated functions which are Couple, Tracking and Phase functions. For Couple function, two signals
with a ratio or offset in amplitude or frequency can be generated. One of two signals with adjustable offset
frequency is an example which can form the two-tone signals for testing the third order inter-modulation
distortion of an amplifier. With Tracking function, two differential signals with equal-frequency, equalamplitude but inverted phase can be produced. Examples such as PECL, LVPECL and LVDS digital signals
or automotive sensors like temperature, speed signals are all able to be simulated by tracking function.
The Phase function is designed to create two signals with specified phase offset. When user wants to
create two quadrature (sine and cosine) signals, the phase offset is set to be 90 degrees in the Phase
function. In conclusion, compared with other arbitrary function generators only equipped with phase
function, AFG-2225 provides great convenience to fulfill the various challenges coming from modern
electronic industries.
High-flexibility of Arbitrary Waveforms Editing
AFG-2225 provides 120MSa/s sampling rate, 10-bit vertical resolution, 4k-point waveform length, and the
maximum waveform repeated rate of 60MHz, regarded as an outstanding arbitrary waveform capability.
There are four ways for AFG-2225 to generate customized arbitrary waveforms, which are editing waveform
via PC software, point-by-point editing on the panel, loading CSV file and loading the captured waveform
from GW Instek GDS-Series Oscilloscopes.
The PC software editing and point-by-point editing particularly provide the way to create the user-defined
and post-modification waveform. CSV file loading capability allows AFG-2225 to produce the waveforms
with complicated math operation result. Engineer can use PC math software to process the integral and
then send the results in CSV format to AFG-2225. With the link to GW Instek GDS-series Digital Storage
Oscilloscopes (DSOs), the waveforms of interest can be captured by DSO and then reconstructed by
AFG-2225. User can capture the waveform during the operation and then reconstructed by AFG-2225 for
further analysis or diagnosis in the laboratory. Thus, plus the dual-channel feature, numerous derivative
applications of capturing signal can be achieved.
