National Instruments PCI-6703 模拟输出设备

PCI-6703 （部件号： 778316-01） 是一款静态 16 电压输出通道模拟输出设备， 具有 16 位分辨率， 可用于软件定时电压输出应用。用户 可以 在 输出 通道 上 将 浮 动 或 接地 负载 连接 到 NI PCI-6703 设备。无需使用外部浮动电源即可完成受控电流环路。用户可以控制 0.1 至 20.2 mA 的电流环路。本环路的一致性为 0 V 至 10 VDC。由于每个通道都与电压通道共用一条接地线，因此请限制来自电流通道的到达电流对电压通道上产生的电压的影响。例如，如果用户在通道上产生20 mA电流，并将该通道恢复到NI PCI-6703，则在阻抗为0.1 Ω的链路中，电压输出将在共享接地线的电压通道上下降2 mV。

该模拟输出器件具有用户定义的上电状态、±10 V 范围、8 条数字 I/O 线、直流输出耦合以及独立的用户定义的上电状态值。PCI-6703 可以连接多种信号类型，例如 LED、精密传感器的电压和电流激励、机电继电器、光隔离固态继电器和 I/O 模块安装机架。该 设备 可 与 NI- DAQ 7.4 或 更高 版本、 不 带 NI 应用 软件 的 .NET 语言、 LabVIEW for Windows、 不 带 NI 应用 软件 的 ANSI C、 Measurement Studio 和 LabWindows/ CVI for Windows 一起使用。它配备了一个 68 针公头 I/O 连接器。

用户应注意不要超过模拟输出设备上输出或输入信号的最大额定值，因为这可能会对计算机或设备造成损害。NI 设备尺寸为 3.9 x 6.9 英寸。在物理维度上。它具有 0 至 55 °C 的推荐工作温度范围，存储温度范围为 -20 至 70 °C.PCI-6703

该器件具有衰减同步功能，当几个计数器正在估计或处理类似的外部信号时，该器件非常有用。例如，假设计数器 0 和 1 设计用于激活脉冲生成，并且每个计数器都使用类似的外部触发器（此外部标志与 I/O 连接器上的 PFI 38 相关联，并且两个计数器选择 PFI 38 作为其 GATE）。在触发信号通过I/O焊盘激增后，信号达到ASIC内部每个计数器的GATE的理想机会可能会相差几纳秒。

National Instruments PCI-6703 analog output device

The PCI-6703 (Part number: 778316-01) is a static 16-voltage output channel analog output device with 16-bit resolution for software timing voltage output applications. The user can connect a floating or grounded load to the NI PCI-6703 device on the output channel. A controlled current loop is completed without the use of an external floating power supply. Users can control the current loop from 0.1 to 20.2 mA. The consistency of this loop is 0 V to 10 VDC. Since each channel shares a ground line with the voltage channel, limit the impact of the arrival current from the current channel on the voltage generated on the voltage channel. For example, if a user generates 20 mA current on a channel and restores that channel to NI PCI-6703, the voltage output in a link with an impedance of 0.1Ω will drop by 2 mV on the voltage channel sharing the ground wire.

The analog output device has a user-defined power-on state, ±10 V range, 8 digital I/O lines, DC output coupling, and independent user-defined power-on state values. The PCI-6703 can be connected to a variety of signal types, such as leds, voltage and current excitation for precision sensors, electromechanical relays, optically isolated solid-state relays, and I/O module mounting racks. The device works with Ni-DAQ 7.4 or later,.NET language without NI application software, LabVIEW for Windows, ANSI C without NI application software, Measurement Studio, and more LabWindows/ CVI for Windows is used together. It comes with a 68-pin male I/O connector.

Users should be careful not to exceed the maximum rating of the output or input signal on the analog output device, as this may cause damage to the computer or device. The NI device measures 3.9 x 6.9 inches. In the physical dimension. It has a recommended operating temperature range of 0 to 55 °C and a storage temperature range of -20 to 70 °C.PCI-6703

The device has attenuation synchronization, which is useful when several counters are estimating or processing similar external signals. For example, suppose the counters 0 and 1 are designed to activate pulse generation, and each counter uses a similar external trigger (in addition, the part flag is associated with PFI 38 on the I/O connector, and both counters select PFI 38 as their GATE). After the trigger signal surges through the I/O pad, the ideal chance of the signal reaching the GATE of each counter inside the ASIC may vary by a few nanoseconds.
