MIMO Introduction
Multi-channel and MIMO transmitter and receiver testing may require synchronization of multiple signal gen-
erators and/or signal analyzers in time and frequency. For example, wireless LAN transmitters can be meas-
ured by multiple receivers operating at the same frequency and with acquisition timing aligned, and
receivers can be tested using synchronized signal generators.
The M9381A VSG and M9391A VSA can be configured to operate in multi-channel configurations with a
shared 100 MHz frequency reference, and an independent local oscillator (synthesizer) for each channel.
This allows them to operate at the same frequency for MIMO operation, and at different frequencies for
modes in which multiple carriers are used, but baseband timing alignment is still required.
The arbitrary waveform playback of the M9381A VSG can be synchronized using a common external trigger
on the backplane of the PXIe chassis. The IQ acquisitions made by the M9391A PXIe VSA for demodulating
MIMO waveforms can be synchronized using a synchronization technique using the backplane of the PXIe
chassis. Refer to the
Keysight M9391A PXIe Vector Signal Analyzer and M9381A PXIe Vector Signal Gen-
erator Programming Guide
The scope of this document is to present the processes of receiving and verifying operation of the Keysight
MIMO PXI Test Solution (see www.keysight.com/find/pxi-mimo). The overall process is:
1. Unpack and inspect your solution.
2. Verify the contents of each box in your shipment matches the respective box content list.
3. Install and cable the modules.
4. Install the software.
5. Redeem your software licenses.
6. Complete the configuration of your MIMO solution and verify operability.
7. Installation is complete. Proceed to use the MIMO Demo Tool, and develop your control programs with the help of
the MIMO Demo Tool source code and the product drivers.
