Please excuse my ignorance but ...

Why isn't the "SIGLENT SVA1032X 3.2GHz 2-port VNA with Spectrum analysis" combined with the "SIGLENT SSA3032X-R Real-time Spectrum Analyzer 9kHz~3.2GHz" ??

Is it just essentially a marketing exercise ?

What can't I do on one machine or the other ?

Is there a technical reason why you would not combine the two machines ?  (This would be backed up by seeing companies buying the two machines I assume.)

Cheers.

Apart from BW all these models have identical SA capability: SSA3000X Plus, SVA1000X and SSA3000X-R.

Look here.

Basically it shows you that the SVA doesn't have the realtime capability, because it doesn't have the necessary HW.

If you are willing to pay the X-R price, I think Siglent can create a "special" SVA for you.

Look here where I posted the inside of a SSA X-R. For those that have seen SVA/SSAX+ you can see that the HW is different.

Apart from BW all these models have identical SA capability: SSA3000X Plus, SVA1000X and SSA3000X-R.

Well, maybe SSA3075X+ is a X-R inside...  ::)

The SVA/X+ can't be licensed from 3.2GHz to 7.5GHz. But the X-R can.

OK.

So essentially, the market might get to a point where it would demand the two instruments be combined.  Or perhaps we have two legacy product lines that will naturally be combined as technology advances.

I think the VNA has a more sensitive front end or lower noise but I could be wrong.

Thanks for the replies so far.

Well the combination is already here as the X-R does the whole job. Of course the technology advances will bring the price down.

BTW, a few years ago I was asking myself this same question that you did.

Off-topic curiosity: A Rigol RSA3015N can be "upgraded" to a RSA5032N and costs only 2.500€, while a Siglent SSA3032X Plus which costs 2.900€ can be converted to a SVA but has no realtime capabilities.

Thinking more on this idea...    ::)  >:D

I wonder if one can convert a SSA3032X-R into a SVA1075X VNA or, at least, a SSA3075X+.

I know that we would loose the realtime capability BUT we would gain the BW increase for several k€ less!  :popcorn:

A ballsy & knowledgeable volunteer is needed...

Adding it to the TO DO LIST.  :)

There are subtle differences in DANL between model ranges.....suggests different HW.

Hi tv84,

I am considering buying a Rigol RSA3015N. Can you point me to the instructions on how to "upgrade" it?
Thanks in front :)
