摘要
针对组建虚拟仪器时不可缺少的硬件部分及仪器与PC间的接口问题,依据USB1.1规 范,采用USBN9604接口芯片和C8051F007单片机,开发了基于USB总线12bits字长的数据采 集/信号发生器.该数据采集/信号发生器具有12位的分辨率,A/D转换速度100 kbps,D/A转换时 间10μs,经实验测试,设备运行稳定可靠.
Aiming at interface problem between pc and parts essential in setting up virtual instrument system, according to USB1.1 bus specification, the 12bits data acquisition/signal generator based on USB is designed by using a USBN9604 and a C8051F007 chips. It has been proved by test that the equipment has 12bits resolution, 100kbps A/D converting time, 10μs D/A converting time and running stable.
