Note If you are creating your own accessory to use with your device, you can purchase the mating connector for the VHDCI cable from NI (part number 778914-01). Whether you use NI cables and accessories or design your own, you should properly terminate cables to avoid improper measurements due to signal reflections, overshoot, and undershoot. Refer to the NI Digital Waveform Generator/Analyzer Help for more information about signal termination. Wiring for Common Measurements Dynamic generati
