Introduction
Overview
Introduction
To support higher order Multiple-Input Multiple-Output (MIMO)
implementation, the characterization of the design becomes more
complicated. Therefore, the tests become even more complicated.
The MIMO modulation analysis measurement enables engineers to
characterize their MIMO designs by providing signal formats demodulation and
the EVM performance results for multiple channels, cross-channel and
streams. It can also display the results in time-domain or frequency-domain.
The measurement provides simultaneous measurements for multiple channels
when connecting to multiple instruments.
This MIMO measurement guide is to demonstrate the WLAN and 5G NR MIMO
measurement (4x4) capabilities in M9410A/M9411A VXT PXIe Vector
Transceiver.
In the case of MIMO, which is most often used in R&D, the M9410A/M9411A
modules with M9010A/M9019A chassis provides the multiple transceivers
needed for simultaneous test of all MIMO channels. The multiple transceivers
for simultaneous test of all MIMO channels provide full and complete set of
MIMO metrics and the test speed is fast since each channel is captured in
parallel.

Option MMO supports 2x2, 3x3, 4x4 MIMO measurement. For 4x4 MIMO
measurement, 4 M9410A/M9411A modules are needed to conduct 4x4 MIMO.
Please refer to the following procedure to setup all the hardware for 4x4 MIMO
measurement.
1. Refer to M9410A/M9411A Getting Started Guide to install M9037A
controller, M9300A reference and 4 M9410/M9411A modules into the
M9019A chassis. Make sure the M9300A reference is installed in timing slot.
For M9019A chassis, the timing slot is slot 10.
2. Connect the M9300A Reference 100 MHz Out port to each
M9410A/M9411A 100 MHz In port with SMB to MMPX cable
(M9410-60009) as figure below.
3. Connect the DUT according to your test need with SMA cables.
4. Connect a mouse and a keyboard to the controller or use a PC to remote
control.
To use MIMO function properly with option MMO, all the M9410A/M9411A
modules must be installed in one chassis.

Launch ModularTRX Application for MIMO Measurement
Launch ModularTRX Application for MIMO Measurement
To use this feature with M9410A/M9411A, you need enable MIMO function
before launching the Modular TRX application. The MIMO configure tool is
needed to enable the MIMO feature, the MIMO configure tool is located in
"C:\Program
Refer to the procedures below to launch the TRX application for MIMO
measurement. Please ensure all the needed modules have been installed
properly before the operation below.
1. Double-click MimoTurnOnTool.exe, a window will pop up as below:
Files\Keysight\X-Series\VXT2".
2. Click OK and restart the controller to make the virtual memory configuration
take effect.
If your ModularTRX application is launched in normal mode previously, the
first two steps are required for MIMO measurement. if your ModularTRX
application is launched in MIMO mode previously, please skip the first two
steps and launch the application directly from step 3.
Click Input/Output > RF Source Tab to check the current status of your
ModularTRX application. If the Source Sync sub-menu is accessible, the
application is in MIMO measurement status. If the Source Sync sub-menu is
invalid, the application is in basic mode.
3. Click to start the application launcher. All the installed modules will
be shown as "Idle" status in the launcher window as below. Select all the
needed modules for MIMO measurement in the launcher. Click Run
Selected and the TRX applications of all the selected modules will be
launched immediately.
