国家仪器 CDA-2990 时钟分配装置
NI CDA-2990(部件编号:784305-01, 784306-01, 140001B-03L)是National Instruments的时钟分配设备.该设备具有8个通道和AC输入/输出耦合.CDA-2990广泛用于通过共享时钟源构建多通道系统.这个8路分配配件使用完全集成的时钟源.NI CDA-2990可以同时在时间和频率上同步多达八个USRP设备.这个时钟分配设备在前面板上带有PPS和10 MHz输入.然后将这些输入分配到八个PPS SMA和八个10 MHz输出.该设备的参考时钟输入功率范围为0 dBm到20 dBm.为了保持信号完整性和电平,每个生成的输出信号在被分割后进一步放大.
The Clock Output on the National Instruments CDA-2990 Clock Distribution Device operates at 10 MHz frequency and provides up to 10 dBm power in regular conditions. The PPS output of the NI CDA-2990 can operate at 5 V maximum and can generate a logic-level pulse waveform. You can power this device through a 6 VDC to 15 VDC power supply with a maximum input power of 6 W. The NI CDA-2990 Clock Distribution Device accepts 10 MHz reference inputs and 1 pulse-per-second reference inputs from Rubidium standard or another compatible external source. These signals are amplified by active component for the generation of matched-length streams to eight output signals.
