- 寬廣的頻率範(fàn)圍：1uHz ~ 80/50MHz
AFG-3000系列 函數(shù)/任意波信號(hào)產(chǎn)生器採用直接的數(shù)位合成技術(shù)(DDS)來產(chǎn)生及輸出各種穩(wěn)定且精準(zhǔn)的波形，頻率*高可達(dá)80MHz(AFG-3081)或50MHz(AFG-3051)，且頻率解析度*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。 
*小1uHz解析度
- 支援多用途變動(dòng)信號(hào)應(yīng)用(調(diào)變, 掃描, Burst)
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)輸出埠讓信號(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等三種介面出發(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 ,週期次數(shù),週期時(shí)間與延遲時(shí)間等規(guī)格。 
- 200MSa/s 高速取樣率
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)*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範(fàn)圍 - 16位元振幅解析度
在16bit的解析下，因?yàn)槊總€(gè)點(diǎn)的振幅解析更為細(xì)緻，讓波形在呈現(xiàn)時(shí)較Smooth，而較低解析度的波形在顯示時(shí)可能就會(huì)有產(chǎn)生部份的鋸齒狀或者較不Smooth，對(duì)於信號(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)，由於16bit*小是0.15mV，所以切成1000等份的線條看起來就會(huì)接近於直線，而12bit*小解析度為2.4mV，無法達(dá)到1mV的解析度，在線條上就會(huì)有可能造成階梯狀的現(xiàn)象。
16 位元提供更好的解析度 - 可任意定義的1M記憶體深度
Long memory 可儲(chǔ)存更複雜、更多點(diǎn)數(shù)的波形資料。AFG-3000提供了1M的記憶體深度，除了具備高彈性的設(shè)定功能，可讓使用者在1M的範(fàn)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)存資料，也可提供記憶體的使用效率；除此之外，機(jī)器還能將所設(shè)定的輸出範(fàn)圍換算成輸出頻率，以減少使用者計(jì)算的時(shí)間。 
任意波形編輯/輸出 - 簡單操作與高彈性的任意波形編輯功能
AFG-3000提供四種方式產(chǎn)生自訂的任意波形, 編輯自訂/PC軟體/檔案載入(.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使用者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。 
支援CSV檔案載入 AFG-3000同時(shí)也支援CSV檔案編輯，CSV檔案格式可由許多方式取得；從EXCEL試算表, PC端軟體, 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軟體匯入到機(jī)器中也可快速取得波形。 
支援CSV檔案
可從從數(shù)學(xué)運(yùn)算軟體載入波形還原功能(DWR) AFG-3000支援直接與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，將所需的波形載入到AFG-3000的記憶體中。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系列示波器載入波形配備PC軟體 AFG-3000也配備了專屬的任意波形編輯軟體，PC軟體除了包含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，讓使用者能夠更靈活的設(shè)計(jì)所需要的波形。 
Sinc + 高斯雜訊的波形
數(shù)位訊號(hào) - 阻抗切換/線上幫助
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，這是由於阻抗不匹配的原因，但透過阻抗切換的功能，AFG-3000輸出的振幅將會(huì)與示波器的一致，能讓使用者在更容易進(jìn)行信號(hào)判讀。而內(nèi)建的Online Help功能可讓使用者在不了解AFG-3000的功能時(shí)，能夠透過Help讓使用者更容易了解各功能鍵的作用。
