content: 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.

content: 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?

content: Quote from: Hugoneus on February 25, 2018, 10:41:52 pmJust 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?

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.
