I just wanted to share, that my SSA 3021XP must have a reflection bridge built in. I'm not sure if all owners know that?
And if I'm right, why do they sell the Siglent Bridge as mandatory for the SSA series when it is just about a license?
It costed me several hours to find the feature, when my self built bridge was not working as I expected at S11 mode. I thought I have to produce the same behavior as the RB3X25 with my bridge.
When I checked what happens when I terminate the TG output with 50 Ohms and I directly a plausible S11 response in Smith chart. After calibration everything worked perfectly without external bridge.

So I see no need to buy an expensive RB3x25 reflection bridge or to play around with self made bridges.
By the way, everything works fine with my upgraded SSA3021XP, but I cannot get the SVA1032X screen as capt bullshot has (SVA firmware seems to be on and also many features as useable). It still looks like an SSA.
As I cannot access the device any more because the "Telnet Acsess Frimware" is not working in this state any more.
Has anyone the same problem and a solution?
