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 adapt dual-signal applications such as differential signaling or 1Q
modulation. The outstanding cost-performance value makes the AFG-2225 a practical instrument to accelerate the development process.
The major features for both channels include 10Vpp output amplitude; 2SMHz frequency bandwidth with 1p Hz resolution; built-in
waveforms of Sine, Square, Ramp (Triangle) and Noise. As to the 19%6~99% 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.
Ih 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.

The Equivalent Function in Dual-Channel
Wide Frequency Range 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
frequency is 25 MHz and offers full-range 14 Hz frequency other dual-channel AFG in this class, AFG-2225 is fully equipped
resolution. The built-in functions include Sine, Square, Ramp/ 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 cannot meet the requirements
of reality.
AFG-2225 offers signal output by DDS technique. The maximum

Correlated Functions of Dual-Channel Differential Signals Quadrature (Sine and Cosine) Signals
The two channels can be used in either independent or correlated such as PECL, LVPECL and LVDS digital signals or automotive
configuration. AFG-2225 provides three correlated functions which sensors like temperature, speed signals are all able to be simulated

an example which can form the two-tone signals for testing the 90 degrees in the Phase function. In conclusion, compared with
third order inter-modulation distortion of an amplifier. With other arbitrary function generators only equipped with phase
Tracking function, two differential signals with equal-frequency, function, AFG-2225 provides great convenience to fulfill the
equal-amplitude but inverted phase can be produced. Examples various challenges coming from modern electronic industries.
D. HIGH-FLEXIBILITY OF ARBITRARY WAVEFORMS EDITING
Direct Panel Operation
Direct Waveform Reconstruction (DWR) Capability
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 GWlnstek 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.

Arbitrary Waveform Editing PC Software
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 GWInstek
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.
