456682
Starting an acquisition without clearing the previous acquisition causes a data overflow error.
The niRFSA Close VI does not automatically clear data. Acquiring data, then starting a second acquisition without explicitly clearing the data from the first acquisition, causes a data overflow error at the beginning of the second acquisition.
Workaround: Add code to your test to clear any data left at the end of an acquisition.

455741
Multi-Record Fetch in program using "localhost/DeviceName" and SFP Session Access Utility returns connection error
If you are using the SFP Session Access Utility and initializing a session with "localhost/DeviceName" in a program, if the program is performing a multi-record fetch, the first call to perform Multi-Record Fetch returns with the following error: Error -1074097835 occurred at niRFSA Fetch IQ (1D Complex WDT NRec 1Chan).vi Possible reason(s): A connection error has occurred. Ensure that the device session is still open with session access enabled. On subsequent runs, the error will not occur.

Workaround: Re-run the program that uses "localhost/DeviceName"

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. See corresponding article for more details. http://zone.ni.com/devzone/cda/tut/p/id/12818

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.

Using NI-RFSA with NI-TClk to synchronize multiple devices acquiring at different I/Q rates results in misaligned data.
When using TClk synchronization where two or more NI RF vector signal anayzers acquire at different I/Q rates, it is possible for the acquired data to 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.

Workaround: Since the skew does not vary with time, users can empirically determine the expected misalignment and correct the acquired data manually.

Upgrading from NI-RFSA 2.6 to NI-RFSA 2.7 causes Express VI to no longer launch.


Workaround: Repair NI-RFSA after upgrading to NI-RFSA 2.7.

395826
Scaling coefficients returned can differ by up to 1e-10.
For a single record IQ 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 multi-record IQ 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 rather small, this difference does not affect amplitude accuracy for any of the devices supported by NI-RFSA.

Setting an IQ Power Edge Trigger with an invalid minimum quiet time on the NI PXI-5661 produces a persistent error.
Setting an invalid minimum quiet time on the NI PXI-5661 will produce an error reporting that the quiet time is invalid. This error will persist even after setting the minimum quiet time to a valid value.

Workaround: Use the niRFSA Reset VI or the niRFSA_reset function to restore all properties or attributes to their default values and re-apply the desired settings.

Reported Version: 2.3    Resolved Version: N/A    Added: 11/15/2012
346251
Unsupported property or attribute error for the Contiguous Multirecord property or the NIRFSA_ATTR_CONTIGUOUS_MULTIRECORD attribute in NI-RFSA Soft Front Panel or missing extended error information.
When using the NI PXI-5661 through the NI-RFSA Soft Panel it is possible for invalid configurations to produce an error message that reports that the Contiguous Multirecord property or the NIRFSA_ATTR_CONTIGUOUS_MULTIRECORD attribute is not supported. Once the error condition is reported, the NI-RFSA Soft Front Panel acquisition will stop. At this point, the value change that caused the error can be changed to another invalid setting and back to the original to receive the correct error message. Correcting the invalid setting will allow the acquisition to continue.

Workaround: When using the NI-RFSA Soft Front Panel, revert the changes that caused the error and re-apply those same changes to get the correct error message. For LabVIEW and C clients of NI-RFSA, place the niRFSA Commit VI or the niRFSA_Commit function after configuration changes that come before a fetch. This will cause the correct error report to be produced. For C NI-RFSA clients, calls to niRFSA_GetError after a fetch call may still report an unsupported attribute error when the return code from fetch is VI_SUCCESS.

Routing signals across segment boundaries on the NI PXIe-1075 chassis can intermittently fail.
The NI PXIe-1075 chassis backplane has the following three trigger buses (segments) that you can use to route digital signals: Trigger Bus 1: PXI Slots 1, 2, 3, 4, 5, and 6 Trigger Bus 2: PXI Slots 7, 8, 9, 10, 11, and 12 Trigger Bus 3: PXI Slots 13, 14, 15, 16, 17, and 18 Backplane signal route requests may sometimes fail if the source and destination devices lie in different segments of the chassis. 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 such that both of them lie in the same trigger bus. Since this error is intermittent, first retry the same route because it may succeed. In LabVIEW, you can retry by conditionally detecting error -26981, clearing the error, and attempting to reserve the same route again.

Using NI-RFSA with NI-TClk to synchronize the PXIe-5663E with the PXIe-5665 or the PXIe-5667 results in misaligned data.
When using TClk synchronization with the PXIe-5663E and the PXIe-5665 or the PXIe-5667, it is possible for the acquired data to 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.

Setting the Mixer Level Offset property or the NIRFSA_ATTR_MIXER_LEVEL_OFFSET attribute to >0dBm and not setting the Mixer Level property or the NIRFSA_ATTR_MIXER_LEVEL attribute causes an error.
If your application sets the Mixer Level Offset property or the NIRFSA_ATTR_MIXER_LEVEL_OFFSET attribute to a value >0 dBm, and does not set the Mixer Level property or the NIRFSA_ATTR_MIXER_LEVEL attribute, the NI-RFSA driver will report an error.

Workaround: Set Mixer Level property or the NIRFSA_ATTR_MIXER_LEVEL attribute to its default -20 dBm value.

NI-RFSA may cause deadlocks on PharLAP when a new NI-RFSA session is initialized in parallel while closing a previously opened NI-RFSA session.
When the niRFSA Initialize VI and the niRFSA Close VI execute in parallel on a PharLAP system, the NI-RFSA driver can cause the OS to deadlock. The system will have to be physically rebooted to be used again.

Workaround: Sequence the niRFSA Initialize VI and the niRFSA Close VI so that they are not executed in parallel. One way to do this is to chain the error out coming out of the niRFSA Close VI into the error in terminal of the niRFSA Initialize VI.

Committing a configuration list with the Number of Records Is Finite property or the NIRFSA_ATTR_NUMBER_OF_RECORDS_IS_FINITE attribute set to false and the Contiguous Multirecord property or the NIRFSA_ATTR_CONTIGUOUS_MULTIRECORD attribute set to enabled will freeze NI-RFSA.
Committing a configuration list with the Number of Records Is Finite property or the NIRFSA_ATTR_NUMBER_OF_RECORDS_IS_FINITE attribute set to false and the Contiguous Multirecord property or the NIRFSA_ATTR_CONTIGUOUS_MULTIRECORD attribute set to enabled will freeze NI-RFSA when calling niRFSAGetAttribute methods, reading an NI-RFSA property in LabVIEW, or calling the niRFSA Commit VI or the niRFSA_commit function. During the freeze, NI-RFSA will be unresponsive and may throw an internal error after an indeterminate amount of time.

Workaround: Set the Number of Records Is Finite property or the NIRFSA_ATTR_NUMBER_OF_RECORDS_IS_FINITE attribute set to true. The Contiguous Multirecord property or the NIRFSA_ATTR_CONTIGUOUS_MULTIRECORD attribute is not supported with the Number of Records Is Finite property or the NIRFSA_ATTR_NUMBER_OF_RECORDS_IS_FINITE attribute set to false.

MAX collapses the Vector Signal Analyzer (VSA) device sub-tree after associating the downconverter with other modules.
MAX will show a sub-tree for each VSA device, which lists the downconverter along with the other modules that make up the VSA (digitizer, LO, RF conditioning (if applicable) and IF conditioning (if applicable) ). After associating the downconverter with the other devices in order to have a working VSA, MAX will collapse the device sub-tree.

Workaround: Manually expand the device sub-tree in order to see the modules that make up the VSA.

When the Number of Records is Finite propertry or the NIRFSA_ATTR_NUMBER_OF_RECORDS_IS_FINITE attribute is set to false and the Contiguous Multirecord property or the NIRFSA_ATTR_CONTIGUOUS_MULTIRECORD attribute is set to enabled, querying a property, an attribute or calling a commit take a long time.
When the Number of Records is Finite propertry or the NIRFSA_ATTR_NUMBER_OF_RECORDS_IS_FINITE attribute is set to false and the Contiguous Multirecord property or the NIRFSA_ATTR_CONTIGUOUS_MULTIRECORD attribute is set to enabled then calling niRFSAGetAttribute methods, reading an NI-RFSA property in LabVIEW, calling the niRFSA Commit VI or the niRFSA_commit function take a long time before returning an error. The same behavior above is observed when the Allow More Records Than Memory property or the NIRFSA_ATTR_ALLOW_MORE_RECORDS_THAN_MEMORY attribute is set to true instead of setting the Number of Records is Finite propertry or the NIRFSA_ATTR_NUMBER_OF_RECORDS_IS_FINITE attribute to false.

Workaround: Enabling the Contiguous Multirecord property or the NIRFSA_ATTR_CONTIGUOUS_MULTIRECORD attribute along with the Number of Records is Finite propertry or the NIRFSA_ATTR_NUMBER_OF_RECORDS_IS_FINITE attribute set to false or with the Allow More Records Than Memory property or the NIRFSA_ATTR_ALLOW_MORE_RECORDS_THAN_MEMORY attribute set to true is currently not support by NI-RFSA.

The Test Panels for NI-RFSG devices fail to load from MAX under certain installation scenarios.
Installing NI-RFSA 2.7 Runtime or higher after installing NI-RFSA 2.6 or lower causes the Test Panels for NI-RFSG devices to stop loading from MAX.

Workaround: Perform a full install of NI-RFSA 2.7 or higher when upgrading from NI-RFSA 2.6 or lower.

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. The connectors are configured once before and after execution where RF IN and RF OUT are reconfigured to their original states. 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 Self Calibrate Range VI or function only once for the entire frequency range so that device settling is minimized.
  • Configure and commit the NI-RFSA session to the desired frequency prior to calling the Self Calibrate Range VI or function to minimize the call time.

The niRFSA Abort VI and the niRFSA Close VI can corrupt recorded acquisition data 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:
    1. Call the Records Done property before the the niRFSA Check Acquisition Status VI.
    2. Wire the reference out output of the niRFSA Property Node to the instrument handle input of the niRFSA Check Acquisition Status VI.
    3. 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 (NI 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.
