Price for the base model seems to be 69980 CNY so appr. 10700 USD.

Nice use of Lecroy Waver-surfer 4000HD case work 

[joeqsmith]

Would like to see the actual documentation for it when it becomes available.   

The marketing sheet and video show mechanical calibration.  Do they offer an ecal for it?

No eCal is available.

IIRC one was hinted at in a disabled menu option on the SVA firmware a while ago. But there have been some changes to the cal menu since and that option is not there anymore.

4 new models of 2 and 4 port VNA's of 4.5 and 8.5 GHz.

Price and release date unknown at this time.
More info as it comes to hand.

Forecast release is July 20 2021.
English datasheet now attached in the OP.

[Sighound36]

TT have you preformed a direct comparsion between the 2 and for port models at all?

[tautech]

TT have you preformed a direct comparsion between the 2 and for port models at all?

Not got my hands on one yet and as the special distributor price is still pretty steep not sure I will. 

AFAICT from the datasheet there are no performance differences between 2 and 4 port models.

Web link added to the OP. Further info to come shortly.

[tautech]

Do they offer an ecal for it?

Not yet in my pricelist however one may be coming or maybe other eCal will be supported if this image from a 8MB PPT presentation is anything to go by:

[tautech]

Price for the base model seems to be 69980 CNY so appr. 10700 USD.

Sub 7.5k 8.5k actually.

Hi Tautech

Pricing for EU is available here. Ships EU
https://www.eleshop.nl/testen-meten/vector-network-analysers.html

This is my Siglent dealer here in NL, i had some barrows from them (some stayed as you know) 
i have asked a demo, so lets see, hope it happens, can't wait

[tv84]

A Siglent costing 26k€ ? ? 

Siglent is turning A-brand... at least in price.

[tautech]

A Siglent costing 26k€ ? ? 

€21700 is list plus options if any.......

And I know more expensive are coming.....
Eg: https://www.eevblog.com/forum/testgear/siglent-ssa5000a-spectrum-analyzers-coming/
https://www.eevblog.com/forum/testgear/siglent-ssg5000a-13-6-and-20-ghz-rf-sig-gens-coming/

Just wish we had these a year ago but instead our customer went for a 26 GHz KS SA @ $250k NZD ! 

[djhatton]

Any news with these things? I am in the market for a VNA and it looks like a half decent product. But they can't actually be serious with the pricing? A us$20k premium for the extra channels and a bw unlock? 

I don't get it. They could totally own the entry level, do that market disruption thing they are trying to be good at. There is a hole there, for sure. But who in their right mind would buy a Siglent for KS/R&S money? Pfft.

Maybe they won't sell many, then drop the price many percents, then sell many

[luudee]

Hi Guys,

two questions regarding the SNA5000A:

1. Can it work as a standard Spectrum analyzer with a TG? Where is the TG output in that case? Any limitations it would have over a SSA3032X Plus?

2. Do the standard old hacks work with this baby?

Many Thanks,
luudee

[1design]

It would be interesting to see the thought process that someone goes through that results in buying one of these

It is slow, with mediocre performance, limited capabilities and non competitive pricing. We are talking serious corner cases here. Maybe Chinese universities or countries with embargoes?

OK, so which units would you recommend instead?
What is better and cheaper?

Thank you
rudi

[1design]

Hi Rudi,

which SNA were you looking at? Each unit has a different alternative to it. It depends on the functionality and performance that you are looking for.
What will you be using the instrument for? Simple filter design, maybe amplifier design, frequency converter design, etc...

The SNA doesn't support frequency offset, so no miyer testing or Transmitter/receiver testing. It has a slow sweep speed that limits manual filter tuning, similar to TTR500 units from Tek. Maybe this is not a issue for you if you do not perform such tasks.

Once you share more details, I can give you some better or cheaper alternatives.

[luudee]

Hi 1design,

thank you for your reply.

My consideration is for all of the above, filter design, amplifier design, frequency converter design, Transmitter/receiver testing ...

My application will most likely be below 3Ghz for now, at some point in the future, I might need to go to 5 GHz.
I do not consider myself a serious user ... thinking of it as a adult toy, to expand my capabilities ...

To be honest, I haven't looked very far at all as to what is available. I have to admit that I am a big Siglent
fan, I like their equipment, and the price seems to be right, and they are hackable ...

Who else makes a comparable/better unit in the same price range?

Many Thanks !
rudi

[1design]

Based on you reply, the SNA5000 family would not suffice to your requirements as it does not support frequency offset measurements.
Nevertheless, of your hart is set on Siglent than my answer might be in vain altogether.

Baseline: SNA5002A(4.5GHz) for $8,499: https://www.tequipment.net/Siglent/SNA5002A/Network-Analyzer/?search=true
Sweep: 150us/point fully called 2 port
Dyn,. range: 125dB (30MHz to 4.5GHz)
Noise fl.:-125dBm/Hz


In your price and frequency range there are a few alternative options:
Tek TTR503(3GHz) for $6,000: Slow sweep speed, no offset freq. options, similar performance to SNA https://www.tek.com/datasheet/vector-network-analyzers
Pico VNA 106(6GHz) for $6,500: 185us/point fully called, no offset freq. option, has AM to PM measurement, lower performance than SNA https://www.tequipment.net/Pico/VNA-106/Network-Analyzer/?b=y&v=99940#description
Copper Mountain M5045(4.5GHz) for $7,895: 70us/point fully called, no offset freq. option, has AM to PM measurement, higher performance than SNA https://online.fliphtml5.com/pbaab/xzks/#p=13
Copper mountain S5054(4.5GHz) for $10,995.00: The same as the M5045 with added frequency offset capabilities.

At the end of the day, if all you want to do is learn and do basic measurements with reasonable accuracy, than a LibreVNA or NanoVNA might be a much smarter way to spend your hard earned cash

LibreVNA: https://www.amazon.com/Analyzer-AURSINC-100KHz-6GHz-Measuring-Parameters/dp/B092Q6W2Z6
NanoVNA: https://nanorfe.com/nanovna-v2.html

When looking at VNA data, there is a lot to compare, I did a VERY rough comparison. The trace noise, dynamic range, uncertainties, calibrated/uncalibrated directivity etc. are all very important when doing precise measurements.
Making sure to check the resBW at which each company specifies their parameters so you compare apples to apples is very important.

If you want to do PA measurements, the Output power range is important together with its accuracy specifications.

Hopefully this helped a bit Personally I would go with Copper mountain for 2 ports.

[tautech]

For the last few days a buddy in the US has said his was coming and no sooner than it had arrived and booted he FaceTime'd me. 
All I could hear while watching him fiddling with it was expletive, expletive, expletive this thing is so fast !
A couple of us in NZ had a small while with webserver control then had to pack it in as the poor US fella had to get some sleep.

~4 weeks and we'll have one to play with. 

[Sighound36]

The SNA5084 is rather good, nice intuitive features, multiple screen presentation, packed with features that are useable and useful. Plus Time domain, TDR and SA modes.

Really nice 12.1" high resolution touch screen, good file management and its just great to use. so far have been quiety impressed, it has a place on the test bench not much equipment gets to stay there, the SNA5084 does.

[egonotto]

Hello,

I can not find a SNA5084 do you mean a SNA5014A?

Best regards
