問題: 有很多不同種類的 SMB(SubMiniature B) 接頭，包含：50歐姆，75歐姆，75歐姆高密度(high-density)，與 mini SMB(75歐姆)。哪一種是由NI硬體裝置所使用的？

解答: SMB 接頭用在多種 NI 硬體裝置上，包含：

• 動態資料擷取裝置(Dynamic Signal Acquisition) - 447x and 446x
• 高速示波器(High-Speed Digitizers)
• PXI 控制器(Controller) - TRIG connectors

這些裝置上的 SMB 為 50 ohm 接頭，接頭外殼大小直徑約為 0.250 英尺。NI 提供多樣的 SMB 連接性與連接線可供選擇：

• SMB-100 - SMB plug 轉 BNC jack cable
• SMB-110 - SMB plug 轉 BNC plug cable
• SMB-120 - SMB plug 轉 BNC jack 內建 10 dB 衰減
• SMB-200 - SMB plug 轉 SMB plug
• SMB-300 - SMB plug 轉 alligator clip
