I realize this is similar to a recent topic but a bit different.
As the "TDR" function in the nanovan is not actually a time-domain process, is there a wat to differentiate between a short or open fault in a cable?
I have previously built a generator which can produce a very short pulse or a step with fast risetime. I have used it in conjunction with a scope as a TDR. It works reasonable well and you can clearly see an open or short in a cable.
Is there a way to replicate tis with a nanovna?
It should work identically - short and opens have 180 degree difference in the phase of the reflection, and that shows up in the synthetic TDR from the frequency sweep.
