數字信號採集卡 M4i.7725-x8 LVDS 250 Ms/s
數字I/O 板卡可用於數字波形的採集和回放。數字波形發生器通常也稱為碼型發生器或流模式發生器。輸入/輸出的電平要麼為特定的（如TTL），要麼電平可以由用戶透過軟體編程。虹科Spectrums的數字I/O 卡可以在內部同步到A/D 卡和D/A 卡以形成混合模式系統。碼型發生器的主要優點是可以作為集成FIFO模式輸出的流模式碼型發生器工作。

一、產品概述
M4i.77xx-x8 系列數字波形採集（邏輯分析儀）卡包括具有 32 個同步通道的版本，可以是具有可編程閾值電平的單端通道，也可以是差分通道。大容量板載內存可以分段記錄不同的波形序列。雖然 M4i.77xx 卡採用最新技術設計，但它們的軟體仍與早期 Spectrum 數字採集卡的驅動程序相容。因此，現有客戶可以使用他們為已經有 10 年歷史的 60 MS/s 數字輸入卡開發的相同軟體，也可以用於 M4i.77xx 系列 720 MS/s 邏輯分析儀。
