串列介面引擎-
The main chip of the usb interface circuit is a cypress semiconductor ' s product, cy7c64613, which has intergrated usb sie ( serial interface engine ) and enhanced 8051. the oscilloscope module is realized according to the real time sampling principle. it has two signal chunnels and a dual 8 - bit dual a / d converter whose most sampling rate is 40msps, so two signal acquisition can occurs in the same time
隨后介紹虛擬儀器測試平臺中各硬體模塊設計實現: usb介面的主晶元是cypress公司的cy7c64613 ,此晶元集成了usbsie和8051核;示波器模塊根據實時取樣原理實現,採用雙8位a / d轉換器,提供兩條信號通道,可以同時採集雙路信號,最高的采樣率為40mhz ;信號源模塊採用直接數字合成( dds )原理實現,它所能產生的信號頻率為10hz 5mhz ,最小頻率解析度為9 . 537hz 。
