特 點
2 5 M H z 基礎型等性能雙通道任意波產生器
正 面
一台抵兩台，等性能雙通道任意波型產生器
AFG-2225在任意波的功能中提供了120MSa/s取樣率、10位元的垂直解析度以及4k點的記憶體深度以及高達
60MHz的波形重複率這樣的規格一般都是在在中階任意波產生器才比較會具備的，更何況在AFG-2225上面
的任意波功能是雙通道都可各自獨立設定任意波形，並且提供所見及所得(WYSIWYG)的面板編輯方式、
表格(CSV)檔案載入、透過GDS系列數位式示波器進行波形重建以及透過任意波形編輯軟體等四種方式來
獲得任意波形。
AFG-2225提供在雙通道使用模式下可進行耦合(Couple)、跟蹤(Tracking)、組合(Combine)以及相位(Phase)
等四種模式，有別於一般的雙通道大部分僅能進行相位(Phase)測試或者不具任何關聯能力，這樣的設計對
於需要測試臨界信號或者失真信號是一大便利。
具備高性能任意波功能
雙通道可關聯性信號輸出
真實等性能雙通道信號輸出
AFG-2225是固緯電子第一台雙通道的任意波函數信號產生器產品。本產品是一台以DDS技術為基礎，
結合任意波功能的信號產生器，提供25MHz頻段，且提供全頻段1uHz的頻率解析度。標準內建正弦波
、方波、三角波(鋸齒波)、雜訊信號以及任意波信號等波形。在任意波部分提供120MSa/s取樣率、10
位元解析度、4k點記憶體深度的任意波編輯功能，並在任意波編輯模式中內建了高達66種函數波形，
讓使用者可以依照所需要的函數進行選用。而在方波的工作週期上也提供了1%~99%的寬度調整，可
作為脈衝波信號源。另外此機種還提供AM/FM/PM/FSK調變、掃描(Sweep)以及計數器(Counter)功能
，以因應不同的種類應用。
目前在市面上大多數的基礎型雙通道函數波形產生器通常僅有其中一個通道的功能較完善，另外一個通道
所具備的功能都會有所折扣甚至於僅具備傳統DDS信號輸出的能力。AFG-2225特有的等性能雙通道信號輸
出功能，就好比將兩台等性能單通道的任意波函數信號產生器放在一起使用，而不是其中一個通道僅有少
數的功能可使用，AFG-2225也是目前業界中在基礎型的任意波產生器中，唯一具備等性能雙通道的機種。
頻率範圍可達1μHz ~ 25MHz

在編輯時更是採用所見及所得(WYSIWYG)的編輯方式，讓使用者非常方便就可以知道目前的所有編輯
狀態。而在通訊介面部分，AFG-2225配備了USB Host/Device通訊介面，透過USB Host可與GW Instek
所有的GDS系列示波器進行直接波形重建的功能與隨身碟的存取，而透過USB Device則可進行電腦端
的遠端控制或者透過專屬的PC端任意波編輯軟體將使用者編輯後的波形傳送到機器中。

SPECIFICATIONS
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 dual-
signal applications such as differential or IQ signaling. 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; 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.
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, equal-
amplitude 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.

特 點
2 5 M H z 基礎型等性能雙通道任意波產生器
正 面
一台抵兩台，等性能雙通道任意波型產生器
AFG-2225在任意波的功能中提供了120MSa/s取樣率、10位元的垂直解析度以及4k點的記憶體深度以及高達
60MHz的波形重複率這樣的規格一般都是在在中階任意波產生器才比較會具備的，更何況在AFG-2225上面
的任意波功能是雙通道都可各自獨立設定任意波形，並且提供所見及所得(WYSIWYG)的面板編輯方式、
表格(CSV)檔案載入、透過GDS系列數位式示波器進行波形重建以及透過任意波形編輯軟體等四種方式來
獲得任意波形。
AFG-2225提供在雙通道使用模式下可進行耦合(Couple)、跟蹤(Tracking)、組合(Combine)以及相位(Phase)
等四種模式，有別於一般的雙通道大部分僅能進行相位(Phase)測試或者不具任何關聯能力，這樣的設計對
於需要測試臨界信號或者失真信號是一大便利。
具備高性能任意波功能
雙通道可關聯性信號輸出
真實等性能雙通道信號輸出
AFG-2225是固緯電子第一台雙通道的任意波函數信號產生器產品。本產品是一台以DDS技術為基礎，
結合任意波功能的信號產生器，提供25MHz頻段，且提供全頻段1uHz的頻率解析度。標準內建正弦波
、方波、三角波(鋸齒波)、雜訊信號以及任意波信號等波形。在任意波部分提供120MSa/s取樣率、10
位元解析度、4k點記憶體深度的任意波編輯功能，並在任意波編輯模式中內建了高達66種函數波形，
讓使用者可以依照所需要的函數進行選用。而在方波的工作週期上也提供了1%~99%的寬度調整，可
作為脈衝波信號源。另外此機種還提供AM/FM/PM/FSK調變、掃描(Sweep)以及計數器(Counter)功能
，以因應不同的種類應用。
目前在市面上大多數的基礎型雙通道函數波形產生器通常僅有其中一個通道的功能較完善，另外一個通道
所具備的功能都會有所折扣甚至於僅具備傳統DDS信號輸出的能力。AFG-2225特有的等性能雙通道信號輸
出功能，就好比將兩台等性能單通道的任意波函數信號產生器放在一起使用，而不是其中一個通道僅有少
數的功能可使用，AFG-2225也是目前業界中在基礎型的任意波產生器中，唯一具備等性能雙通道的機種。
頻率範圍可達1μHz ~ 25MHz
全頻段1μHz解析度
內建120MSa/s，10位元，4k點數的
任意波形編輯功能
提供CH1/CH2等性能雙通道信號輸出
雙通道功能提供耦合(Couple)，
追蹤(Tracking)，組合(Combine)以及
相位(Phase)運算能力
方波的工作週期可達1% ~ 99%

AFG-2225在介面的設計上，除了採用全數位的操作設計搭配旋鈕進行微調外，所提供的3.5吋LCD螢幕
在編輯時更是採用所見及所得(WYSIWYG)的編輯方式，讓使用者非常方便就可以知道目前的所有編輯
狀態。而在通訊介面部分，AFG-2225配備了USB Host/Device通訊介面，透過USB Host可與GW Instek
所有的GDS系列示波器進行直接波形重建的功能與隨身碟的存取，而透過USB Device則可進行電腦端
的遠端控制或者透過專屬的PC端任意波編輯軟體將使用者編輯後的波形傳送到機器中。
