| Missing documentation on reference level and mechanical attenuation limits when using the PXIe-5668 with PXIe-5698.
The NI RF Vector Signal Analyzers Help should include the following information:
- When using the PXIe-5668 with PXIe-5698, the Preamp Enabled property or the NIRFSA_ATTR_RF_PREAMP_ENABLED attribute, the reference level is limited to -35 dBm to limit the distortion in the system.
-
- When using the PXIe-5668 with PXIe-5698, the Preamp Enabled property or the NIRFSA_ATTR_RF_PREAMP_ENABLED attribute, the mechanical attenuation is locked to 5 dB. This improves the match between the PXIe-5698 and the mixer. Unlike the internal preamplifier on the PXIe-5668 that follows after RF attenuation, when a lower DANL is achieved by setting RF attenuation to 0 dB, the PXIe-5698 is before the RF attenuation and reduces the system noise figure to about 4 dB which reduces DANL to around -170 dBm/Hz.

When using the PXI-5661 through the NI-RFSA Soft Panel, invalid configurations may produce an error message that reports the Contiguous Multirecord property or the NIRFSA_ATTR_CONTIGUOUS_MULTIRECORD attribute is not supported. After the error condition is reported, the NI-RFSA Soft Front Panel acquisition stops.

| The niRFSA Self Calibrate Range VI execution time is greater than expected.
In some instances, calling the niRFSA Self Calibrate Range VI or the niRFSA_SelfCalibrateRange function takes much longer than expected because of device settling, which can occur each time the device is reconfigured. When the VI or function executes, the RF IN and RF OUT connectors are configured twice.

Extended execution time is most noticeable when you repeatedly call the Self Calibrate Range VI or function for a single point, varying the frequency slightly for each call.
Workaround: Perform either of the following options as a workaround.- Call the niRFSA Self Calibrate Range VI or the niRFSA_SelfCalibrateRange function only once for the entire frequency range so that device settling is minimized.

When using TClk synchronization with the PXIe-5663E and the PXIe-5665 or the PXIe-5667, the acquired data may be misaligned. The misalignment manifests itself as a skew where the data from one device appears to be leading/lagging the data from the other device. The time delay between the data acquired by the master and a slave is constant for the combination of the hardware settings configured on the two devices. This skew is repeatable and does not vary with time.

In that scenario, error -26981 A protocol violation was detected, is returned. This error is intermittent, and its frequency depends on the embedded controller or MXI interface device used in the chassis.
Workaround: There are two possible workarounds for this issue: Change the location of the source and destination devices for the hardware route so both of them lie in the same trigger bus.

| Low-power signals may appear at fixed intervals in power spectrum data.
Low-power signals may appear at fixed intervals when performing a power spectrum acquisition. When performing an acquisition narrower than the hardware instantaneous bandwidth, the signals can appear in the lower frequency bins and upper frequency bins of the acquisition. When performing a multispan acquisition, the signals can appear at the boundary of each single span spectral acquisition that makes up the total acquisition.
Workaround: The low power signals represent the dither signal on the digitizer. Although the dither signal is at a frequency that is outside the bandwidth of the equalized response, the power of the dither signal can leak into the equalized response, depending on the resolution bandwidth and the FFT window type. You can remove the dither signal from the power spectrum data through one of the following methods:- Using a narrower resolution bandwidth.
- Disabling the dither signal.
- Choosing a different FFT window type. This solution may be less effective than the previous solutions, depending on the resolution bandwidth.

| Installer built with LabVIEW Application Builder and NI-RFSA 2.7.5 fails.
An installer build with LabVIEW Application Builder fails when NI-RFSA 2.7.5 Full is included. The system returns an error about "Missing NI-RFSA_SFP" dependency.
Workaround: Include the NI-RFSA Full and Runtime as well as an NI-RFSA example in the installer.

| Scaling coefficients returned can differ by up to 1e-10.
For a single record I/Q acquisition, scaling coefficients obtained from the niRFSA Get Scaling Coefficients VI or the niRFSA_GetScalingCoefficients function could be different from the scaling coefficients obtained from the niRFSA Fetch IQ (1D I16) VI or the niRFSA_FetchIQSingleRecordComplexI16 function. Similarly, for a multirecord I/Q acquisition, scaling coefficients obtained from the niRFSA Get Scaling Coefficients VI or the niRFSA_GetScalingCoefficients function could be different from the scaling coefficients obtained from the niRFSA Fetch IQ (2D I16) VI or the niRFSA_FetchIQMultiRecordComplexI16 function. The difference in the scaling coefficients can be up to 1e-10.
Workaround: There is no workaround for this issue. However, since the difference in coefficients is small, this difference does not affect amplitude accuracy for any NI-RFSA devices.

| When using synchronization examples on PXIe-5663/5663E devices, the examples display a PLL Lock error.
When configuring the master and slave PXIe-5663 devices for the first time, the synchronization examples do not export the clocks correctly, resulting in a PLL lock error.
Workaround: Run NI-RFSA Getting Started Spectrum or NI-RFSA Getting Started IQ example on the master device prior to using the synchronization examples. This workaround is required after a system restart or a reset device is called on the master PXIe-5663/5663E.

| The niRFSA Abort VI and the niRFSA Close VI can return DSP overflow warnings if a record acquisition is in progress and RF list mode is aborted on VST devices.
Workaround: There are two workarounds for this issue:- Do not call the niRFSA Abort VI while a record acquisition is in progress. This workaround does not help for an infinite records case.
- Complete the following steps:
- Call the Records Done property before the the niRFSA Check Acquisition Status VI.
- Wire the reference out output of the niRFSA Property Node to the instrument handle input of the niRFSA Check Acquisition Status VI.
- If the done? output of the niRFSA Check Acquisition Status VI is TRUE, you can safely use the number of records that are returned upon fetching.

| When using a vector signal transceiver device, changing the Reference Clock source from PXI_CLK to OnBoardClk requires a ten second delay for stability.
When using a vector signal transceiver device (PXIe-5644R/5645R/5646R), changing the Reference Clock source from PXI_CLK to OnBoardClk requires the hardware to disable and then re-enable the onboard Reference Clock. Disabling and re-enabling the onboard Reference Clock is necessary to provide the PXIClk route enough isolation from the onboard clock. After being re-enabled, the clock requires ten seconds to reach stability.Workaround: N/A
