PCI-6541 模块化仪器 数字I/O处理

PCI-6541是一款用于连接数字电子产品的高速PCI模块化仪器，具体功能和应用如下：
它提供了32通道的高速数字I/O处理，每通道的最高传输速率可以达到50MB/s，并且通道的方向是可控的。此外，其高容量的板载内存具有触发和模式编列的功能，并能通过NI-HSDIO驱动器配置5.0V、3.3V、2.5V或1.8V的逻辑电压。
PCI-6541可以通过同步内存核心（SMC）不仅利用数字化仪、任意波形生成器和其他数字波形生成器/分析仪，创建混合信号测试系统；还可以通过同步多种数字设备建立低失真（low-skew）、多通道系统，非常适合应用于高速量测之环境及需求，如IC逻辑讯号量测、平行数据传输及高速输入输出量测与控制等。
同时，PCI-6541提供的样式比对（Pattern Match）功能，可以用来监控重要的数字输入讯号，当发现数据状况改变时，系统会立即呼叫中断进行警急状况处理。

PCI-6541

Pci-6541 is a high-speed PCI modular instrument for connecting digital electronics with the following functions and applications:
It provides 32 channels of high-speed digital I/O processing, with a maximum transfer rate of 50MB/s per channel, and the direction of the channel is controllable. In addition, its high-capacity onboard memory has trigger and mode scheduling capabilities and can be configured with 5.0V, 3.3V, 2.5V or 1.8V logic voltages via NI-HSDIO drives.
The PCI-6541 enables the creation of mixed-signal test systems using a synchronous memory core (SMC) that leverages not only digitizers, arbitrary waveform generators, and other digital waveform generators/analyzers; It can also build low-skew, multi-channel systems by synchronizing multiple digital devices, ideal for applications in high-speed measurement environments and requirements, such as IC logic signal measurement, parallel data transmission, and high-speed input and output measurement and control.
At the same time, the PCI-6541 provides a Pattern Match function, which can be used to monitor important digital input signals, and when the data status changes, the system will immediately call an interrupt for emergency processing.
