IQ Origin offset result for multicarrier configurations is reported in Subblock IQ Origin Offset Mean result property
Quadrature error and IQ Gain Imbalance results are not supported for multicarrier configurations
Updated nominal spacing definition for carrier aggregation cases as per Rel 15 Specification June 2019 v 15.6.0. For waveforms compliant to previous Rel 15 releases, use user-defined spacing definition.
Composite EVM result does not include the EVM of DMRS and PTRS. You must set ModAcc Composite Results Include DMRS and ModAcc Composite Results Include PTRS properties to True to include the respective EVMs in the Composite EVM result
Dropped support for ModAcc EVM Exclusion Period property for Downlink measurement as per the 3GPP NR specification Rel 15 June 2019
Dropped support for Cleaner Spectrum property on PXIe-5830 and 5831
Obsoleted RFmxNR Analyze (IQ) and RFmxNR Analyze (Spectrum) APIs. Use RFmxNR Analyze (IQ, 1 Wfm) and RFmxNR Analyze (Spectrum, 1 Wfm) APIs instead
When you set the Frequency Range property to Range 2 , the new enums, FR2 Category A , FR2 Category B , added to the gNodeB Category property are the only valid enums.

Automating the Installation of NI Products
You can automate the installation of most NI products using command-line arguments to suppress some or all of the installer user interface and dialog boxes.
If the NI product you are installing uses Microsoft .NET 4.0, the .NET installer may run before any NI software installs and may require a reboot before the installation of NI software begins. To avoid a .NET reboot, install .NET 4.0 separately before you install NI software.
For more information about automating the installation of NI products, refer to the following KnowledgeBase articles:
For more information about silent installations of individual NI products, refer to Customize and Automate Installation of a Single Installer .
For more information about silent installations of NI products in a suite, such as NI Developer Suite, refer to Customize and Automate Installation of a Suited Installer .
To determine what version of NI Installers your product contains, refer to Determine Type and Version of My National Instruments Installer .
