Demonstrating multi-site configuration
While the 4-port VNA is running, you can also create a different, fully-functioning VNA which would run at the same time
as the 4-port VNA. The only practical limit to the number of VNA instances is the CPU speed of the host controller. The
benefit of creating Multi-site VNAs is measurement throughput. You could test multiple devices at the same time.
In this demo we use multiple M937XA to demonstrate multi-site configuration. The key point of this demo is to show
flexibility of the setting.
The mainframe should have the latest version of the software for this demonstration. Refer to
In the following instructions, two pairs of 4-port operation are configured. Use these instructions as a general
guide if installing a different number of modules.
Install Modules
As seen in shown figure, install four modules. Install semi-rigid cables (M9370-20006 for LO In/Out, M9370-20018 for Trig
In/Out, M9370-20019 for Ref In/Out) to connect each module. Also, connect 50 ohm loads on LO In of the first module
and LO Out of the second module for each pair of 4-port configuration M957XA.
