Chapter 1 Introduction you do not need the RTSI cable for system triggering and timing on the PXI. In addition, a phase-locked loop (PLL) circuit accomplishes the synchronization of multiple NI PXI-6115/6120 devices or other PXI devices which support PLL synchronization by allowing these devices to all lock to the same reference clock present on the PXI backplane. Refer to the Phase-Locked Loop Circuit section of Chapter 3, Hardware Overview, for more information. Detailed specifications o

Chapter 1 Introduction Route the analog lines separately from the digital lines. When using a cable shield, use separate shields for the analog and digital halves of the cable. Failure to do so results in noise coupling into the analog signals from transient digital signals. Mating connectors and a backshell kit for making custom 68-pin cables are available from NI. The parts in the following list are recommended for connectors that mate to the I/O connector on the device: Honda 68-pos
