Scalar Network Analyzer

I would like to measure the Return loss of an antenna at Ka Band. My VNA doesn't go that high, but I do have an Agilent SA that will using an external mixer. If I have a tracking generator I believe that I can accomplish this and use the external mixer as my detector. Has anyone used a tracking generator with the Agilent E4407B? I don't have the option installed, but don't see why I wouldn't be able to use an external one. A little help?

why don't you just use max hold, and sweep it once?

Yep that worked.

Thanks
