Re: Measuring Phase with Agilent E5062A ENA

Hi Dave. The machine does actually have quite a bit of capability and I find it vastly superior to the older HP VNA's I have had in the past.? The problem is it is so poorly documented or not documented at all (at least in the operators manual) it makes using it or learning about it frustrating and very time consuming.

Like in the case of Expanded Phase......turns out that does exactly what I want it to do but you will find nothing useful describing the function or how to use it or any of it's limitations etc. Hard to believe that Agilent would put out such a powerful "VNA" and not tell people how to use many of it's common commands for making all sorts of neat measurements. I would have assumed there was some kind of app note of other documentation that detailed such things.

Anyway, thanks for the ideas but for now at least in this case I have found what I need.

You could save the data as a Touchstone file the import it into the software used for the VNWA.



and display as "c. phase" which is the phase unwrapped - I assume the c is for continuous.

Does your ENA support any sort of macro/programming? If so, you might be able to program something in there to unwrap phase.

There's no doubt the ENAs are pretty poor compared to the PNAs. The ENAs were developed in Japan and the PNAs in the USA. Support on the older ENAs on the Keysight forums is almost nonexistent.? The latest ENAs run the same firmware as the PNAs, so things are different.

I have the firmware of an ENA running on a PC (actually a virtual machine) as an emulator, but the ENA software is quite poor.
