Thanks for the video Shahriar. I was hoping to see you demo the Gore cables and show the amplitude and phase stability of a Metrology grade cable when moved etc. If possible please consider showing us the various grades of cable in a future network analyzer video.

Those fancy cables look like Audiophool cables...

Hah - except in the case of RF it would be pretty easy to prove they are better.

I assure you they are not. Not every application needs them, but they are needed in some circumstances. :)

Sorry I didn’t get to do that. My Gore cables are very rigid and long and it made it difficult to setup on my bench.

Great video and very informative. Looks like a nice machine and I totally agree on the benifit of the short depth. I used to use an enoumous HP machine came in two sections and needed its own trolley.

Does the ZNLE have TDR and gating modes btw?

Those features exist in the ZNL model (as options) but sadly not in the ZNLE model. :(

Just wondering what sort of stuff can you do with TDR at 6GHz?
Is that a high enough frequency to see the effect of an end launch SMA on a PCB for example or does that require a higher frequency?

It can still be handy. You can find damaged cables for instance.

With gating you can detect and remove the effect of external reflections when measuring antennas outside of a anachoic chamber.

As far as I know it doesnt really need hardware mods. I guess if you can export a touchstone file you can just run an FFT on the frequency data to calculate it yourself.
