AFG-3000系列 函數(shù)/任意波信號(hào)產(chǎn)生器采用直接的數(shù)字合成技術(shù)(DDS)來產(chǎn)生及輸出各種穩(wěn)定且精準(zhǔn)的波形，頻率zui高可達(dá)80MHz(AFG-3081)或50MHz(AFG-3051)，且頻率分辨率zui高可達(dá)1uHz。內(nèi)建標(biāo)準(zhǔn)波形有Sine, Square, Triangle, ramp, pulse, noise等種類的波形。

zui小1uHz分辨率

內(nèi)建的調(diào)變波形可建構(gòu)在Sine, Square, Triangle, Ramp等波形上，且可調(diào)整透過INT/EXT來進(jìn)行信號(hào)調(diào)變功能，且提供專屬調(diào)變信號(hào)輸出端口讓信號(hào)更容易取得輸出信號(hào)。 accordingly.

PWM to Control & Test the Motor Speed

內(nèi)建的掃描功能可設(shè)定為INT/EXT/manual等三種接口出發(fā)，且可設(shè)定LOG/LIN兩種掃描方式。

Burst功能提供了Gate與N Cycle兩種設(shè)定模式, Gate模式可設(shè)定內(nèi)建標(biāo)準(zhǔn)信號(hào)(Sine, Square, Triangle, Ramp)的On/Off時(shí)間比例，且可透過控制極性(Polarity)或相位(Phase)來進(jìn)行控制, N cycle模式則可設(shè)定相位角度 ,周期次數(shù),周期時(shí)間與延遲時(shí)間等規(guī)格。

任意波的波形是透過一串的數(shù)據(jù)點(diǎn)數(shù)所組成，輸出的頻率可用取樣率除以波形點(diǎn)數(shù)來取得，輸出頻率=取樣率/波形總點(diǎn)數(shù)。對(duì)zui大取樣率為200MSa/s的AFG-3000來說，如果透過兩個(gè)點(diǎn)來表示波形，可以產(chǎn)生100MHz訊號(hào)，同理，如果取樣率為100MSa/s，則產(chǎn)生的波形為50MHz。舉例來說，當(dāng)訊號(hào)透過100個(gè)點(diǎn)來組成，當(dāng)取樣率越高，所組成的波形頻率也會(huì)越高。

越高的取樣率能提供更高的頻率范圍

在16bit的解析下，因?yàn)槊總€(gè)點(diǎn)的振幅解析更為細(xì)致，讓波形在呈現(xiàn)時(shí)較Smooth，而較低分辨率的波形在顯示時(shí)可能就會(huì)有產(chǎn)生部份的鋸齒狀或者較不Smooth，對(duì)于信號(hào)的判讀也會(huì)有一定的影響。例如1V切成1000個(gè)等份(每等份1mV)，由于16bitzui小是0.15mV，所以切成1000等份的線條看起來就會(huì)接近于直線，而12bitzui小分辨率為2.4mV，無法達(dá)到1mV的分辨率，在線條上就會(huì)有可能造成階梯狀的現(xiàn)象。

16 位提供更好的分辨率

Long memory 可儲(chǔ)存更復(fù)雜、更多點(diǎn)數(shù)的波形數(shù)據(jù)。AFG-3000提供了1M的內(nèi)存深度，除了具備高彈性的設(shè)定功能，可讓用戶在1M的范圍內(nèi)取任意的點(diǎn)數(shù)進(jìn)行編輯或輸出，除了能提供更多/更長的儲(chǔ)存數(shù)據(jù)，也可提供內(nèi)存的使用效率；除此之外，機(jī)器還能將所設(shè)定的輸出范圍換算成輸出頻率，以減少用戶計(jì)算的時(shí)間。

任意波形編輯/輸出

AFG-3000提供四種方式產(chǎn)生自定義的任意波形, 編輯自定義/PC軟件/檔案加載(.csv)/從GW GDS-2000示波器輸入

前面板編輯操作

AFG-3000提供強(qiáng)大的面板操作設(shè)定，提供WYSIWYG (What You See Is What You Get)的操作方式，從編輯到輸出都可直接透過面板設(shè)定完成，除了具備高彈性的編輯方式外，在儲(chǔ)存/輸出等設(shè)定下，都可透過立即的圖表顯示讓用戶更容易了解目前波形的狀態(tài)與所想要輸出的波形內(nèi)容。

支持CSV檔案載入

AFG-3000同時(shí)也支持CSV檔案編輯，CSV文件格式可由許多方式取得；從EXCEL電子表格, PC端軟件, 或者從AFG-3000儲(chǔ)存。只要將編輯好的CSV檔案透過USB隨身碟或者PC軟件匯入到機(jī)器中也可快速取得波形。

支持CSV檔案

可從從數(shù)學(xué)運(yùn)算軟件加載

波形還原功能(DWR)

AFG-3000支持直接與GW GDS-2000系列示波器連接，在不需要PC控制的情況下，直接透過USB Cable將示波器上看到的波形存到AFG-3000的任意波形功能上，且可選擇不同的通道，將所需的波形加載到AFG-3000的內(nèi)存中。這樣的功能能讓工程師更容易進(jìn)行波形分析。

可直接從GDS-2000系列示波器加載波形

配備PC軟件

AFG-3000也配備了專屬的任意波形編輯軟件，PC軟件除了包含AFG-3000面板上所有的功能外，更包含了更多種類的應(yīng)用波形，如Rayleigh / Gaussian / Normal Noise, Pseudo ternary, Bipolar-AMI, Manchester, Differential Manchester, RS232, NRZ等，且提供數(shù)種波形計(jì)算與檢視功能，讓用戶能夠更靈活的設(shè)計(jì)所需要的波形。

Sinc + 高斯噪聲的波形

數(shù)字訊號(hào)

從AFG-3000輸出信號(hào)到示波器中往往會(huì)發(fā)生振幅準(zhǔn)位放大約兩倍的情況，這是由于阻抗不匹配的原因，但透過阻抗切換的功能，AFG-3000輸出的振幅將會(huì)與示波器的*，能讓用戶在更容易進(jìn)行信號(hào)判讀。而內(nèi)建的Online Help功能可讓用戶在不了解AFG-3000的功能時(shí)，能夠透過Help讓用戶更容易了解各功能鍵的作用。

阻抗切換

在線幫助功能

AFG-3000配備了標(biāo)準(zhǔn)的通訊接口，GPIB, RS-232, 以及USB接口，且當(dāng)用戶如果需要進(jìn)行系統(tǒng)整合應(yīng)用，AFG-3000也提供了符合IEEE 488的標(biāo)準(zhǔn)Command List，方便使用者進(jìn)行程控。

AFG-3000所設(shè)計(jì)的4.3“ LCD屏幕，擁有著480x272的高分辨率，除了能將所有的設(shè)定顯示在屏幕上之外，圖形顯示功能也能讓用戶快速且輕松了解目前的設(shè)定狀態(tài)。
