Dynamic Generation

Dynamic generation is a clocked operation where binary data is sent from the NI digital waveform generator/analyzer to the DUT across multiple digital channels.

The NI 655x can generate complex digital patterns up to 20 bits wide at a variety of voltage levels synchronous to any of several clock sources. The data can be generated as simple waveforms or based on complex scripts. External triggers can control the data generation, and the Pattern Generation Engine can export several types of events to indicate the progress of the generation.

In addition, the NI 655x allows for precise subperiod timing control between the generated data and the exported Sample clock. All these options make the NI 655x a versatile digital pattern generator.

NI 655x devices support the open collector drive type, which means that they can set the configured data channels to a high-impedance (Z) state when the channels are configured to drive the Generation Voltage High Level.
