Siglent SNA5000A two and four port VNA's

[tautech]

Thanks for the response EE-digger,

Yeah, having read this thread and similar elsewhere I’m aware the SA functionality is very basic.  I have sort of the inverse problem with my SVA1032 which is a nice SA but a very limited VNA.  But having properly working even limited SA capability in the SNA can eliminate the need to break configuration sometimes and that can be useful.

What I was hoping to hear from tautech is if the problems that have been reported are fixed.  Also, if he thinks Siglent is done doing whatever they ever intend to do with it at this point.

tautech ?

EE-digger has been in coms with my RF beta tester hendorog whom accompanied me to HQ recently where he has struck up a good working relationship with one of Siglents RF engineers.

EE-digger's comments are interesting in that there is some RF magic/tricks used for SA capability in SNA5000A.
I've been a bit outta the loop on latest discussions about any possible improvements.......

And just to be clear, when I refer to RF magic, I'm referring to what is likely a practical arrangement to a seasoned RF guy, but magic to me 

And to add a bit of positive here,  the power measurements by the SA and the source output levels are spot on across the entire range.

The ability to copy channels, then simply drag them back on top of the original as a reference, with colors automatically assigned, AND to have reference amplitude control that is independent for that channel copy, is freaking wonderful.  I should also mention that ALL colors can be changed within the THEME function, easily saved and easily defaulted back to standard.

The remote control interface was very well done and the ease of use of SCPI commands very helpful to semi-automate repetitive setups or tests.

Your last comment regarding your needs and the SVA1032 limitations hit home.  The SVA1032 is a nice little unit but the VNA side is limited.  OTOH, as I've mentioned, the SNA5000A was targeted (by me) to replace my venerable PNA.  To me the PNA is still a gold standard but the SNA5000A probably does 80 to 90% of what it can do, and maybe another 10 to 20% of newer functions that the PNA can't.  Couple it with a more modern interface and I think the SNA5000A is a winner in the VNA department.  I'm keeping my big PSA though and the SVA1032 will handle most of my EMI / EMC compliance testing needs on its SA side.  As I mentioned to you in a PM, the SVA1032 very closely matches the PNA on various channel measurements like Occupied Bandwidth, Channel Power and Adjacent Channel Power.

Hi EE-digger,

Thanks very much for this reply and for the PMs.  I just tried to send you a response PM.  The system said it was sent but I don't see it in my "Sent" folder so I don't know what's going on.  If you didn't receive it, please let me know and I'll try again.

Thanks !
Russ

I've received one PM from you.  The messaging system is funny sometimes.  Refresh the page you're on (inbox, sent messages, etc.).  Sometimes that will fix the status.
