Japanese characters not allowed in waveform names or script names on PXIe-5413/5423/5433 waveform generatorsNI-DAQmx-based waveform generators allow waveform names with Japanese characters, but on PXIe-5413/5423/5433 waveform generators the NI-FGEN API will report error -1074101561 (0xBFFA82C7): "The script contains an invalid character or symbol. Replace the invalid character with a valid symbol or alphanumeric character." Workaround: Change waveform names to use only characters from the English alphabet. |

Synchronization between the PXIe-5413/5423/5433 and the PXIe-5442 does not work in Standard Function output mode and with the PXIe-5442 as the master deviceWorkaround: To synchronize the PXIe-5442 and a PXIe-5413/5423/5433 in Standard Function output mode, use the PXIe-5413/5423/5433 as the master device or read the TClk period and then set the minimum TClk period to a higher value by calling niTClk Synchronize. |

Device data underflow failure occurs when generating waveforms with a size of 196 or 200 in Arbitrary Sequence mode on the PXI-5422 waveform generatorThe PXI-5422 product documentation states that the minimum supported waveform size is 192 samples and that larger values that are multiples of 4 are also supported. However, a device data underflow error occurs when using waveform sizes of 196 and 200. Workaround: Double the number of samples on the host and double the sample rate. |

Write waveform function times out when streaming on PXIe-5413/5423/5433 waveform generators if the sample rate is below 256 kS/s or if the sample rate is below 4.5 MS/s and the allocated waveform size is below 1.2 k samplesWorkaround: Duplicate samples on the host and increase the sample rate of the waveform generator accordingly. |

Options String "DriverSetup=MemorySize:" doesn't simulate memory size correctly on PXIe-5413/5423/5433 waveform generatorsThe value passed for the MemorySize tag in the Driver Setup string is ignored in simulated instrument sessions. The simulation logic assumes 128 MB of usable memory per channel for PXIe-5413 and PXIe-5423 waveform generators, and 512 MB of usable memory per channel for PXIe-5433 waveform generators.
Workaround: There is currently no known workaround for this issue. |

PXIe-5413/23/33 Arb Sequence stepped trigger has poor alignment, compared to initial start trigger, varying as the arb sample rate is changedThe delay for a stepped trigger on the PXIe-5413, PXIe-5423, and PXIe-5433 to occur increases and has more jitter the lower the sample rate. Workaround: There is currently no known workaround for this issue. |

NI-FGEN devices may fail under Linux kernel DMA remappingAttempts to use NI-FGEN devices may fail on Linux kernels that have enabled DMA remapping. The Linux kernel logs will contain errors similar to the following: Linux distributions that enable DMA remapping by default include Ubuntu 22.04 with kernel 6.8 or higher and Ubuntu 24.04.
Workaround: Modify the Linux kernel DMA remapping configuration as outlined in https://www.ni.com/r/iommu-linux.
