content: Dear EEVBlog members,I would like to start a discussion in order to clarify the hw differencesinside one group of devices like the mentioned in the subject above (SSA, SVA and SNA).The idea was born due to the fact that e.x. SSD5034X differs from SSD5054X in hwso that if you like to upgrade the SSD50xxX model to a SSD5104X model you have tochoos the SSD5054X and not the lower ones.Is this the case for the listed devices below too?Which one to take to upgrade ex. to SSA3075X Plusor to SSA3075X-R and so on.Have someone the corresponding information's or couldpoint to a related thread if already exist.Price according to Batronix pageSiglent SSA30xxX Plusxx: 15, 21, 32, 75price: 1.4, 1.5, 2.7, 7.7kESiglent SSA30xxX-Rxx: 32, 50, 75price: 4.8, 8.9, 10.8kESiglent SSA508xAx: 3, 5price: 10.0 22.3kESiglent SVA10xxX VNAxx: 15, 32, 75price: 1.6 3.5 9.1kESiglent SNA50xxAxx: 02, 12, 22, 32 (two port)price: 7.9 17.5 29.9 35.8kExx: 04, 14 (four port)price: 15.1 25.8 kEMany thanks in advance for your effort.Markus

content: Dear tautech,thanks for your reply, but could you please clarifyhow you could know that all four versions listed belowdiffer in such way that someone could not tweak alower version like SSA3032X+ to a SSA3075X+.by a hack like from SAS3021X to SAS3032X in the past.But perhaps you could not give officially this informationto the community as this will decrease the Siglentprofit - I understand this totally.Hope that someone else could give same info's on thisissue and is not in a relation ship to the Siglent company.Siglent SSA30xxX Plusxx: 15, 21, 32, 753 different HW's.ByeMarkus

content: Quote from: markus_jlrb on July 01, 2023, 01:32:03 pmRelease dates.For all Plus models, SVA1015X was the first released however VNA capability was an option therefore = SSA3015X+ we know today. Later the SVA1015X was increased in price and VNA capability became standard.SSA3021/32X+ was released next and as mentioned, study of datasheets reveals some specs identify they are slightly better spec'ed than the 1.5 GHz models = different HW.SSA3075X+ and all 5.0/7.5 GHz models came later so from simple deduction, if earlier HW could meet their spec, they would've been released at the same time as 2.1/3.2 GHz capable models.

content: Sorry Tautech,perhaps my question was not clear enough.What for my as a private customer and userof Siglent devices is interesting, how to savemoney by tweaking an upper model of thesame device group to a more powerful model.In order to achieve this someone has to knowwhich model could be tweaked, not to purchasethe wrong one that is restricted in capabilities.Like already mentioned the SDS5034X vers theSDS5054X model. If someone decide to buythe SDS5034X device he could not upgradeto SDS5104X due to hardware restrictions.So to reach the 1GHz BW you have mandatoryto buy a SDS5054X device.So for me the same question arise what concernsthe SSA, SVA and SNA devices and what totake into consideration when purchasing sucha type with the intention to upgrade it.This could not be decided by looking into the specas someone have to look inside the deviceto see if there are differences between themodels of the same device class.Thanks to the guys that post this findings in thisforum.I have a bunch of Siglent devices in my labwhere such upgrade was possible in the pastEx.SSA3021X => SSA3032XSDS1104X-E=> SDS1204X...But I would like now to know hw to reach the7.5GHz boarder by a SSA and/or SVA modelwith reduced costs for private usage, not fora professional purpose.Hopefully you could now better understand myintention of writing this thread and I hopesomeone else could benefit of the findingswhat concerns this topic.So if someone have already this information,would be fine to share it with the communityif not already done in an other thread.Many thanks in advanceMarkus

content: Quote from: markus_jlrb on July 02, 2023, 06:33:59 amClear as crystal.Quote100% correct, this info is in the SDS5000X thread.QuoteGet at least a 5 GHz model however the cheapest option is SSA3075X Plus but not possible to convert it to a SSA3075X-R realtime analyser as they have different HW but do have VNA capability.Then the focus comes back on SSA3032X-R andifthey can be improved.^ This is where you need concentrate your efforts.QuoteLike I said, I always understood what you are looking for and clear as crystal !Hopefully after 10 years dealing I have some detailed understanding of the model structures and how they relate to release dates/product development.
