This application allows to provide the multi-port S parameters measurement solution with the switch matrix module.
The application software controls the calibrations and measurements for VNA and Switch matrix and gets the data from actual VNA application.
Then the measurement data is converted and transferred to a VNA viewer. The VNA viewer pretends as a multi port VNAs.
In the following example, you can make a S parameter measurement as if you work on a 16 port VNA.
M9164A/B
M9165A/B
P9164A/B
P9165A/B
Up to four 2x16 PXI switch modules are supported.
Note: Only 4 or 2 port ECal is supported. Mech cal and N756xA multiport Ecal are not supported.
The console panel handles the following tasks.
Define the port configuration
Specify the number of measurement channel
Actives the VNA viewer
Activates the calibration wizard.
Save the measurement setting.
See Sample Measurement Procedure
The VNA viewer handles the following tasks
Configure the measurement setting excepts the number of channel.
Make a measurement
Observe the test result
VNA viewer has "Keysight Network Analyzer" as the title of application.
Actual VNA application measures the actual measurement in background and transfer the data to the VNA viewer after a conversion. It will be hidden after the console panel is launched. When you want to see the actual VNA application works, click File > Settings > Set measurement visible. Do not change any settings on it.
The VNA viewer has the product number and port as the title of application.
On the console panel, click File > Settings to show he Settings dialog box.
Address: VISA address for an actual VNA application. Do not use this address to remote for this application. See Remote Control.
Connected to: The product information of the actual VNA.
Set measurement visible: Activate the actual VNA application in order to monitor the operation.
Fixed low gain by default: The setting for receiver gain is set at low for all ports automatically in order to reduce time for the calibration. When you need to set it at high, uncheck this.
Note: These settings remain after the application reboot.
You can control the virtual VNA (VNA Viewer) with SCPI commands for VNAs. Use HiSLIP connection at address 30 (default).
TCPIP0::<PXI controller name pr localhost >::hislip30::INSTR. ("hislip" is case-sensitive)
The address can be changed in the Stimulus Tab of console panel.
The *IDN? returns the product and serial numbers of VNA viewer. On the VNA viewer, click System > Help > About NA to confirm its product information.
Note: Do not send the corresponding commands whose softkey is grayed out in the VNA viewer.
