A protocol violation error occurs when using an NI PXIe-1075 chassis

When routing triggers across segments on the NI PXIe-1075 chassis, a protocol violation error may occur. The NI PXIe-1075 has three bus segments: slots 1 through 6, slots 7 through 12, and slots 13 through 18. If the devices are located in different segments, this issue may occur. Some features, such as NI-TClk, when used for synchronization applications, internally route triggers.

Last value is held for a few samples before jumping to idle value when Wait Behavior is set to "Hold Last Value" and Idle Behavior is set to "Jump To Value", only if waveform size is not a multiple of 2 (PXIe-5413/5423) or multiple of 4 (PXIe-5433)

The PXIe-5413/5423/5433 waveform generator firmware will incorrectly be in the "Wait Behavior" state, instead of the "Idle Behavior" state, for a few extra samples at the end of the waveform if the waveform size is not a multiple of 2 (PXIe-5413/5423) or multiple of 4 (PXIe-5433). By default, both wait behavior and idle behavior are configured for the same "Hold Last Value" option. This issue is only noticeable if the wait and idle behaviors are configured to be different.

The issue is in the ni5433k.sys kernel library and the instrument firmware.

Workaround:

Configure wait and idle behaviors to be the same.

Use a waveform size that is a multiple of 2 (PXIe-5413/5423) or multiple of 4 (PXIe-5433).

Japanese characters not allowed in waveform names or script names on PXIe-5413/5423/5433 waveform generators

NI-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 device

Workaround:

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 generator

The 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.

Channels do not stop at the same time when aborting arbitrary waveform generation on two-channel PXIe-5413/5423/5433 waveform generators

When aborting generation on a session that is controlling two channels on the same waveform generator, the abort message is sent by NI-FGEN at two different times: once for channel 0 and then again for channel 1. In standard function mode, the output signal will transition to the "Idle Behavior" state when the abort message for the first channel is applied, but this is not the case for arbitrary waveform mode.

The issue is in the ni5433k.sys kernel library and the instrument firmware.

Workaround:

Switch to a flat DC waveform before aborting or modify the application to not require an abort. Abort is not necessary on scripts that do not repeat forever or in single trigger mode for arbitrary waveforms or arbitrary sequences.

Workaround:

Arbitrary waveform download feature of the NI-FGEN Soft Front Panel fails on PXIe-5413/5423/5433 waveform generators

The NI-FGEN Soft Front Panel can only write arbitrary waveform data to one channel at a time, which is not supported on PXIe-5413/5423/5433 Waveform Generators.

Workaround:

You can use standard function mode in the NI-FGEN Soft Front Panel or use an arbitrary waveform mode example in LabVIEW, LabWindows/CVI, or Visual Studio.

Options String "DriverSetup=MemorySize:" doesn't simulate memory size correctly on PXIe-5413/5423/5433 waveform generators

The value passed for the MemorySize driver setup option is ignored in the simulated session. 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. The issue is in the ni5433NIFgenPlugin.dll library.
