Discovered the following two items I wanted to leave somewhere regarding usage.
1. the SVA now supports saving in SNP, or S parameter format. It saves as S1P. This is very handy for bringing the VNA sweep of a network to an external program for massaging. This is not in Siglent docs nor in firmware revision guide.
With a quality cable attached and calibrated to the end, attached a small antenna eval board for a response plot, with or without markers. When saved as STA or CAL, neither one could load back the working state and screen appearance.
2. Enter the CSA save format. This is not in Siglent docs nor firmware revision guide. CSA saves calibration AND state combined. When you load a CSA file, you will return to where you left off, with cal in place, entire setup in place including markers, etc.
Also, if you find something that is not in Siglent docs, look at their manual for their higher end model, the SNA5032A.
If there is a thread dedicated to usage, please move this there.
