PCI-6601 计数器/定时器设备

5 V，4通道计数器/定时器设备—PCI‑6601执行编码器位置测量、事件计数、周期测量、脉冲宽度测量、脉冲生成、脉冲串生成和频率测量。 该模块具有四个计数器/定时器、数字去抖动滤波器和兼容TTL/CMOS的数字I/O。PCI‑6601可执行一路高速DMA传输。

PCI-6601 （部件号： 777918-01） 执行编码器位置估计、事件检查、周期估计、脉冲宽度估计、脉冲生成、脉冲准备生成和频率估计。PCI-6601可以执行一次快速DMA交换。NI PCI-6601 是 一 款 定 时 和 计算机 化 I/ O 小 工具， 可 与 PC 兼容 PC、 PXI 框架 或 CompactPCI 机 体 中的 PCI 总 线 配合 使用 。NI PCI 6601 提供 32 个 双 向 数字 通道 和 多达 32 行 专门 可 配置 的 TTL/ CMOS 兼容 高级 I/ O。

PCI 6601 National Instruments 设备上的计数器在每个计数器上提供 8 倍和 2 倍的预缩放（预缩放可能会受到限制）。

每个预分频器都由一个小的基本计数器组成，该计数器计数为八个（或两个）并移动。此计数器专门用于此应用，可以记录比通用计数器更快的标记。广泛有用的计数器上的 CtrnSource 运动将是与简单计数器分离的标志。预缩放预计将用于两个计数器周期和频率估计，其中估计是在不断的、乏味的信号上进行的。无法仔细阅读预缩放计数器，因此用户无法确定自上次移动以来发生了多少条边。如果在使用 8 倍预缩放时最多有 7 个错误，或者在使用 2 倍预缩放时有多达 1 个错误，则用户可以利用预缩放来计算边缘。 PCI 6601 配备一个 68 针公头 SCSI-II 型 I/O 连接器。

计数器/定时器设备可以使用传统的NI-DAQ 7.4.4进行校准，该版本与LabVIEW、LabWindows/CVI、Microsoft Visual C++、Microsoft Visual Basic和Borland C++等软件包或应用开发环境（ADE）兼容。

PCI-6601 Counter/timer device

5 V, 4 channel counter/timer device - PCI‑6601 performs encoder position measurement, event counting, period measurement, pulse width measurement, pulse generation, pulse train generation, and frequency measurement. The module features four counters/timers, a digital dejitter filter, and TTL/CMOS compatible digital I/O. PCI‑6601 performs a high-speed DMA transfer.

The PCI-6601 (Part number: 777918-01) performs encoder position estimation, event checking, period estimation, pulse width estimation, pulse generation, pulse preparation generation, and frequency estimation. The PCI-6601 can perform a fast DMA exchange. The NI PCI-6601 is a timed and computerized I/ O gadget that works with a PC-compatible PC, PXI framework, or PCI wire in a CompactPCI body. The NI PCI 6601 offers 32 bi-directional digital channels and up to 32 lines of specially configurable TTL/ CMOS-compatible advanced I/ O.

Counters on PCI 6601 National Instruments devices offer 8x and 2x pre-scaling on each counter (pre-scaling may be limited).

Each pre-divider consists of a small base counter that counts eight (or two) and moves. This counter is specifically designed for this application and can record tags much faster than general-purpose counters. A CtrnSource movement on a wide range of useful counters would be a sign of separation from simple counters. Prescaling is expected to be used for both counter cycles and frequency estimates, where estimates are made on constant, boring signals. The prescale counter cannot be read carefully, so the user cannot determine how many edges have occurred since the last move. If there are up to 7 errors when using 8x prescaling, or up to 1 error when using 2x prescaling, the user can take advantage of the prescaling to calculate the edge. The PCI 6601 is equipped with a 68-pin male SCSI-II Type I/O connector.

Counter/timer equipment can be calibrated using traditional NI-DAQ 7.4.4, This version is compatible with packages or application development environments (ades) such as LabVIEW, LabWindows/CVI, Microsoft Visual C++, Microsoft Visual Basic, and Borland C++.
