mmWave OTA Validation Test Software 1.0 Known Issues

An Error Occurs when Executing the Simulation Sequence Due to External References in the Configuration File

Executing the simulation sequence located in the TestStand Examples folder results in a error message stating a TCP error during the Positioner Initialize step.

The error occurs because the configuration file for the simulation sequence defines the BojayEthercat positioner instead of the simulation positioner. The attempt to communicate with the positioner causes this communication error.

Workaround:

1. Open the the following configuration file: C:\Users\Public\Documents\National Instruments\TestStand 2019 (64-bit)\Examples\OTA Test\Sequences\Simulation Sequence.csv
2. Change Line 17 from {Locals},Positioner.Type,BojayEthercat to {Locals},Positioner.Type,SimulationPositioner

Increased Memory Consumption for Long Test Sequences

Executing long OTA measurements with TestStand uses a large amount of memory, which may cause Windows to quit working.

Workaround:

1. Go to Configure»Station Option and select Disable Result Recording for All Sequences. This reduces the memory consumption to a normal 1 GB to 2 GB range. However, keep in mind that this is a global station option so it not only effects this sequence but other sequences as well.
2. Go to Configure»Result Processing and select Disable Report Generation.

Unexpected Behavior Occurs When the Move Home button is Selected in the mmWave OTA Test Positioner SFP

When the Move Home button is selected in the mmWave OTA TestPositioner SFP, the positioner moves to the current offset that specifies the new home then moves back to the actual home. This unexpected movement can lead to tangled cables and may cause things to fall off the positioner if not properly fixed or removed, for example the antenna or spirit level. 

Workaround: There is currently no known workaround for this issue.

An error message displays when opening the mmWave OTA Test Visualizer from a remote desktop connection.

If you connect to a system using a remote desktop and open the mmWave OTA Validation Test Visualizer, an error message may appear that states a DLL cannot be loaded. The error occurs because there is a windows problem when running OpenGL hardware-acceleratedprograms through remote desktop (RDP) sessions.

Workaround:

• Disable hardware acceleration in you program or graphic card driver, if the option to disable is available.
• For ATI E6460 (PXIe-8880)/E4690 (PXIe-8135) and Windows 10:
  • Uninstall the ATI/AMD drivers until only the Microsoft compatibility drivers are in use, as this driver does not seem to have hardware acceleration support, or
  • Rename the following driver file found at C:\windows\system32 that is responsible for the OpenGL support: atig6pxx.dll to atig6pxx.bak

The Cut Plane Setting is not Applied to Cut Analysis (all beams) Graphs in the mmWave OTA Test Visualizer

It is not possible to select the Elevation Plane when Cut Analysis (all beams) is selected as the measurement visualization.

Steps to reproduce:

1. Select Cut Analysis (all beams).
2. Select the Cut Analysis tab.
3. In the Cut Settings window, select Elevation Plane.

Note that the graph still shows the Azimuth Plane.

Workaround: There is currently no known workaround for this issue.
