To use the Signal Studio software in a multichannel configuration with M9381A PXIe VSGs, the following must be true to ensure the system works properly.
The Signal Studio software assumes the VSG follows the multichannel reference solution typical configuration, using the accompanying configuration tools. Refer to the LTE/LTE-Advanced Multi-Channel, Reference Solution Startup Guide for more information. Also refer to the “Multi-Channel Reference Solution Typical Configuration” section of the M9381A PXIe Vector Signal Generator Configuration Guide.
Multiple VSGs should be configured using the Multi-Channel PXIe Config Utility. This program configures the backplane triggering, alignments, self-test and 89600 VSA software-hardware configuration.
The VSGs are assumed to be used in a multichannel system, not as individual standalone VSGs.
For example, if you configure four VSGs using the Multi-Channel PXIe Config Utility, it is assumed that all four VSGs are used together all the time. There should never be a case where any one of the four VSGs is used individually.
