Ok - I will try adjusting the adjusting the number of data points or averaging (I know the VNA has an averaging feature).
However, I'm still not clear how I measure the impedance of this cable. I think my questions are:
- Which S-parameter should I be set on for the channel? I believe this is...
Ok. So in the attached picture I have two graphs with markers at 2, 5, and 8 GHz plotting S11. One has the graph type set to Log Magnitude and the other has the graph type type to set to Smith Chart.
I think the log mag. graph doesn't tell me much. So in the Smith Chart, for example, at 5 GHz...
Hello,
I have a Wiltron 37269A Vector Network Analyzer (w/ Time Domain capabilities).
The DUT is a cable that has one connector at each end (SMA typically) and can vary in length from a few inches to several feet. Typically we plot S11 (VSWR) and insertion loss (S21) over a certain frequency...
