Dynamic Generation Wiring Considerations

You may need additional parallel termination resistance at the destination for optimal signal quality during dynamic generation, depending on the loading of the device under test (DUT). Refer to the NI Digital Waveform Generator/Analyzer Help for information about signal termination. The following figure shows how the NI 6555/6556 generates data through a matched impedance system.

2. 50 Ω source impedance (Rs)
3. 50 Ω cable
