这PXI国家仪器公司-6713(零件号:777795-01, 185860-01)模拟输出模块可以利用其内部20 MHz时基或通过RTSI总线接收的时基。此外，如果用户想要设计利用内部时基的小工具，他们可以对小工具进行编程，以通过RTSI总线将其内部时基驱动到另一个被修改以获得该时基信号的小工具。这个时钟源，不管是在附近还是来自RTSI公共汽车，都被这个小工具直接用作基本的重复源。启动时的默认设计是利用内部时基，而不驱动RTSI总线时基信号(该时基可由软件选择)。零件号码185860-01仅适用于主板版本的PXI 5713号。

该器件有8个模拟输出通道，分辨率为12位，最大更新速率为1 MS/s，模拟输出电压范围为-10 V至10 V。PXI-6713是DAC0OUT、AOGND和EXTREF。DAC0OUT是模拟输出通道0的电压输出信号，EXTREF是所有模拟输出通道的外部基准电压输入。用户可以利用该输入来减小DAC输出的电压摆幅，同时保护动态范围。

I/O连接器上的两个棒通过自复位线从PC控制电源供电+5 V。过电流情况消失后，电线会自然复位。这些引脚被称为DGND，可以用来控制外部计算机硬件。对时序的所有外部控制PXI-6713模拟输出模块通过10个名为PFI0至PFI9的可编程电容输入来控制。这些PFI是双向的。作为输出，它们是不可编程的，反映了许多DAQ、波形产生和通用定时信号的条件。NI设备的尺寸为6.3 x 3.9英寸。在物理维度上。它的推荐工作温度范围为0至50°C，储存温度范围为–20至70°C。

The National Instruments PXI-6713 (Part Number: 777795-01, 185860-01) Analog Output Module can utilize its inside 20 MHz time-base or a time-base received over the RTSI bus. Furthermore, if the user wants to design the gadget to utilize the inside time-base, they can program the gadget to drive its interior time-base over the RTSI bus to another gadget that is modified to get this time-base signal. This clock source, regardless of whether nearby or from the RTSI bus, is utilized straightforwardly by the gadget as the essential recurrence source. The default design at startup is to utilize the inner time-base without driving the RTSI bus time-base signal (this time-base is software selectable). Part number 185860-01 is for the board only version of the PXI-5713.

The device has 8 analog output channels with a resolution of 12 bits and a maximum update rate of 1 MS/s. It has an analog output voltage range of -10 V to 10 V. The analog output signals on the PXI-6713 are DAC0OUT, AOGND, and EXTREF. DAC0OUT is the voltage output signal for analog output channel 0 and EXTREF is the outside reference input for all analog output channels. The user can utilize this input to diminish the voltage swing on the DAC outputs while protecting the dynamic range.

Two sticks on the I/O connector supply +5 V from the PC control supply by means of a self-resetting wire. The wire will reset naturally a couple of moments after the overcurrent condition is evacuated. These pins are referenced to as DGND and can be utilized to control outside computerized hardware. All external control over the timing of the PXI-6713 Analog Output Module is directed through the 10 programmable capacity inputs named PFI0 through PFI9. These PFIs are bidirectional. As outputs they are not programmable and mirror the condition of numerous DAQ, waveform generation, and general purpose timing signals. The NI device measures 6.3 x 3.9 in. in physical dimensions. It has a recommended operating temperature range of 0 to 50 °C, and a storage temperature range of –20 to 70 °C.
