Parameters, such as number ofsegments in sequence list, maximum number of waveformsin memory, and number of samples available for waveformstorage, are flexible and user defined.—OnboardMemory Size8 MB standard:8,388,608 bytes32 MB option:33,554,432 bytes256 MB option:268,435,456 bytes512 MB option:536,870,912 bytes—Output Modes Arbitrary Waveform mode and Arbitrary Sequence mode —ArbitraryWaveformModeIn Arbitrary Waveform mode, a single waveform is selectedfrom the set of waveforms stored in onboard memory andgenerated.—ArbitrarySequenceModeIn Arbitrary Sequence mode, a sequence directs the NI 5422to generate a set of waveforms in a specific order. Elementsof the sequence are referred to as segments. Each segment isassociated with a set of instructions. The instructionsidentify which waveform is selected from the set ofwaveforms in memory, how many loops (iterations) ofthe waveform are generated, and at which sample in thewaveform a marker output signal is sent.—MinimumWaveformSize(Samples)TriggerModeArbitraryWaveformModeArbitrarySequenceModeThe MinimumWaveform Sizeis sample ratedependent inArbitrarySequence mode.Single 16 16Continuous 32 192 at >50 MS/s96 at ≤50 MS/sStepped 32 192 at >50 MS/s96 at ≤50 MS/sBurst 32 192 at >50 MS/s96 at ≤50 MS/s
