同步至 GPS/IRIG/1588 时间基准
要将PXIe机箱同步至以上提到的三种时间基准,你需要用到“多设备PXI_Clk10 驯服构架”。这将使用到PXI-6682H来接收信号,继而将其转换至一时钟源,PXIe-6674T可以使用设疑时钟源来对齐PXI_Clk10.这些设备作为“用于PXI Express的NI PXI_Clk10的驯服”的设备一同出售。
多机箱同步的配置
通常来说,当要同步多个PXI或者PXI Express机箱时,你需要一个主机机箱和多个从机机箱。然而,当要同步至一个外部标准信号时,推荐在每个机箱搭配使用PXI-6682H与PXIe-6674T,并且分别将每个机箱的PXI-6682H和PXIe-6674T与原始的信号源相连。如果无法使用多个6682H,此时系统可以设置成默认的主/从模式,主机箱中配有能够完全驯服PXI_Clk10的硬件设备。
