Equivalent Dual-Channel Provides Augmented Value for Customers
'-SW lnstek is launching AFC-2225, its first basic level dual-channel arbitrary function generator, which provides superior features in its
class. Eloth channels are equipped with same characteristics to adapt dual-signal applications such as differential signaling or IQ
modulation. The outstanding cost-performance value makes the AFC-2225 a practical instrument to accelerate the development process.
The major features for both channels include 'lD‘v'pp output amplitude; 25MHz frequency bandwidth with 'lj.r Hz resolution; built-in
waveforms of Sine, Square, Ramp [Triangle] and Noise. As to the 'l%~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, AFC.-2225 carries
features ofi'IiMfFM_r'PM,iFSI<I,r’SUM Modulation, Sweep, Burst and Frequency Counter, which can be applied to various communication fields
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 AFC-2225 with other devices, which
provide the fieriibility ofwaveform generation for more practical usages. With link to CW lnstek EDS-series Digital Storage Oscilloscopes
[D505], the waveforms ofinterest can be captured and reconstructed. User can also use the arbitrary waveform PC software to edit the
waveform and then send to AFC-2225 directly, or save the waveform into flash drive and then transfer to AFC-2225.

and vehicle electronic simulation signals, the similar or identical
waveform capabilities are required for both channel outputs. Unlike
other dual-channel AFC in this class, AFC-2225 is fully equipped
with Equal ‘53P3PlllilE5 P" dual '?"~*tP“i5- ii-’lP5t Pm‘-'3l‘¢h3""El
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.

Correlated Functions of Dual-Channel
Differential Signals
The two channels can be used in either independent or correlated
configuration. AFC-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. Cine oftwo signals with adjustable offset frequency is
an errample 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,
equal-amplitude but inverted phase can be produced. Examples
Cruadr'atur*e {Sine and Cosine} Signals
such as PECL, L‘v'PECL 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
E-I'D degrees in the Phase function. In conclusion, compared with
other arbitrary function generators only equipped with phase
function, AFC-2225 provides great convenience to fulfill the
various challenges coming from modern electronic industries.

Direct Waveform Reconstruction [D"rill'Rj Capability
AFC-2225 provides l2DMSa,ls sampling rate, ID-bit vertical
resolution, 4k-point waveform length, and the mariimum waveform
repeated rate of 6DMHz, 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 CS‘v' file
and loading the captured waveform from Cwlnstek 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
CS‘v' file loading capability allows AFC,-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 CS‘v' format to AFC}-2225. With the link to Cwlnstek
CD5-Series Digital Storage Oscilloscopes [DSOsj, the waveforms
of interest can be captured by DSO and then reconstructed by
AFC-2225. User can capture the waveform during the operation
and then reconstructed by AFC--2225 for further analysis or
diagnosis in the laboratory. Thus, plus the dual-channel feature,
numerous derivative applications of capturing signal can be
achieved.

such as simulating pulse and transient signals without purchasing
eritra advanced function generator and pulse generator.
AFC-2225 provides friendly panel operation setting as well as
