This VBScript program shows how to send commands that allow you to view specific 'custom' windows, and sweep specific channels, during a UI (Cal Wizard) or remote calibration.
This VBScript (*.vbs) program can be run as a macro in the VNA. To do this, copy the following code into a text editor file such as Notepad and save it on the VNA hard drive as CalWindow.vbs. Learn how to setup and run the macro.
These commands are used to show and sweep specific windows and channels:
The following command sweeps the Cal Windows before remote acquisition:
