content: Exciting newsSiglent has released product information on their chinese website for a real-time spectrum analyzer with 5 and 7.5GHz range, 40MHz bandwidth.https://www.siglent.com/products-overview/ssa3000xr/It also looks like the SSA3000X Plus and SVA1000X series are getting 7.5GHz versionsI think 2020 is going to be a exciting year for Siglent :-)

content: Really nice news to see, now the inexpensive SA players have broken into the higher bandwidths. I hope they have a VNA version on the way too, even if only a single port like their current lower bandwidth offerings.Looks like it's got 40MHz realtime bandwidth too!

content: Yes this new SSA3000X-R range is not to be confused with the recently updated SSA3000X Plus range which will have only a 7.5 GHz version coming early-mid 2020 to add to the existing 2.1 and 3.2 GHz versions.

content: Looks pretty interesting. Slightly worse phase noise than the Rigol and no IF output though. More expensive too, possibly? (although I guess it depends on what options are included and how they are priced).These two making a mockery of the Keysight and R&S pricing though.

content: Quote from: 0culus on December 20, 2019, 03:22:07 amThey've changed it. It was there yesterday. However, that's Keysight's lowest benchtop model that supports Real Time analysis, so seems like a reasonable comparison. Without all the options enabled, its not that different. E.G. frequency range can be just 10MHz to to 3GHz. DANL is worse (-164) without NFE option. But even with just the basic options, you need to spend 5 times as much to get RTSA. I don't know why they require you to have the 80MHz b/w option before supporting RTSA.

So, why Siglent need compare they products with Rigol. Is Rigol some kind of "reference" level for Siglent. No.Much better ones need be "reference" just as is also with audiophiles, reference quality speakers or amplifiers and then compare all others to these. So...

The series params are striking similar.

I see the data on screen in the video. A number of VSAs have that ability. But I would like to output that demodulated bitstream from the instrument in real time, either via a dedicated TTL port, or via LXI. I looked at the programming manual and it was not apparent how to get at the demodulated data.

IDK.But I know 2 beta testers that maybe can take this up with the product managers to see how this might be accomplished however maybe not in real time.

content: Hi everyone,I have some questions and I’m sure some of you can answer them easily …I am comparing the specs of two spectrum analyzers – the Siglent SSA3032X-R and the Rohde & Schwarz FPC1500 (in the COM2 kit version). In terms of VNA and reflection measurements, R&S states “The R&S FPC is a vector network analyzer that utilizes an integrated VSWR bridge to achieve one ­port vector network analysis, with a Smith chart display available.” Crystal clear.For the SSA3032X-R, I feel confused. Like others, I came across two sets of datasheets for this device, labeled E01A and E02A.In datasheet E01A there is no notion of VNA at all, and for VSWR measurement, an optional, external reflection bridge is needed.In datasheet E02A, VNA with s11 and s12 is mentioned as a standard. The device provides a "1-path-2-port vector network analyzer and a distance-to-fault locator for S-parameter measurement, cable and antenna testing". Its VNA specs specify Lin Mag, Log Mag, Phase, Group Delay,SWR, Smith Chart, and Polar Chart. Were the reflection measurements are discussed in detail (VSWR, Return Loss, Reflection Coefficient), on page 13, the note (still present in E01A) that this requires an option isremovedfrom this version of the document. Yet, on page 23, the reflection bridge is again listed as an option.Adding to the confusion, the international Siglent website page for this device refers includes a reference to the E01A (old?) datasheet.Also, the international Siglent site doesnotlist the reflector bridge as an accessory for the SSA3032X-R, but the European Siglent site does.So, my questions are:How can I know when I purchase a device that it meets the E02 datasheet? Is it certain hardware, or a certain software version?A device that meets the E02A should have VNA (including s11 and s21) as a standard, according to the datasheet. I understand that CSVW is closely related to s11. But would I need additional hardware or software to perform VSWR, Return Loss, and Reflection Coefficient measurements?Any other thoughts on Siglent SSA3032X-R vs. Rohde & Schwarz FPC1500 (FPC-COM2 kit) are also welcome...Thanks!

Despite this manual has "E02A" in its file name, it says both for the "Vector Network Analyzer Mode" and the "Distance-To-Fault Mode" that these are "only available on SVA1000X series.". Am I missing something? They should be available as well for the SSA3000X-R, right?!?QuoteI see you write "in the VNA mode'. Just to be sure: does this VNA mode do the VSWR, Return Loss, and Reflection Coefficient measurements as mentioned in the datasheet (there they are not listed under VNA but under Reflection)? Do you get a screen like the shown screenshot?And just to be sure: do I understand properly the fact that the reflection bridge is listed accessory in datasheet E02A is an error?Sorry I keep on asking, but before committing to any purchase, I'd like to be sure what's included, and what is optional...

content: Quote from: RBBVNL9 on February 28, 2021, 10:26:51 pmYes it is not clear however VNA and DTF modes have certainly been added to X-R models a few FW versions ago.QuoteQuote from: RBBVNL9 on February 28, 2021, 10:26:51 pmYes, no.VNA mode certainly offers VSWR, Return Loss, Smith charts and Phase measurements however Reflection Coefficient measurements are only in SA mode where indeed you need an additional bridge and in order to use it correctly it needs be Normalised before connecting the DUT.Bridges connect between TG and RF IN however for VNA work they're not required as the stimulus comes from the TG port and their reflections bounce back in for single port VNA S11 measurement types.S21 measurements require the use of RF IN also for pass through DUT measurements.No as in the screenshot is for Reflection Coefficient measurements in SA mode.Quote from: RBBVNL9 on February 28, 2021, 10:26:51 pmNo it's not an error but an optional accessory for SA mode and can be used on any of the current Siglent SA's or combo units; SVA or X-R.Quote from: RBBVNL9 on February 28, 2021, 10:26:51 pmThe options are listed here below accessories:https://www.siglenteu.com/spectrum-analyzers/ssa3000x-r/There are 5 SW options for X-R and of note is the EMI software licensing which is currently offered in a promotional package with a nice set of near field probes when purchased with any Siglent SA:https://int.siglent.com/info/detail-40.htmlAll SW licenses are active and free for 120hrs before you need consider any you might chose to purchase later as they each can be added at any time by the owner.

With latest 3.2.2.5.1R1 firmware upgrade installed.I'm encountering what seems to be a glitch when I'm in the RTSA mode. I've been working with Ohio to troubleshoot the problem, but they've been unable to duplicate my symptoms on their instruments.The problem has to do with the Max Hold function in the RTSA/Density mode. It doesn't work on my RTSA unless the Averaging is first set to a value other than 1!I'm not sure if it is appropriate to discuss this topic on the forum?Regards,Nelson - Seattle

content: Hi tautech,a question to the SSA3032X-R specs:What is the effective bandwidth in digital modulation analysis mode? The specs state a Symbol Rate of up to 25Msps * Points/Symbol --> max. 150Msps (approx. 100MHz eff. analysis BW), unlike the comment in same specs about: "The analysis BW is same with real-time BW in RTSA mode" --> so only max. 40MHz?Furthermore, does the SSA really "manage" a 256 QAM with 4096 length data analysis? How fast does it?Could you clarify and maybe show some modulation analysis testings - to get an idea of "real" analysis BW limits?Many thanks!

content: Quote from: nh-sea on July 18, 2022, 09:02:31 pmHi Nelson,congratulations for your SSA3000X-R unit - I am evaluating the purchase of one, too.Could you share your experience with some screenshots of Digital Modulation Analysis (i.e. 64QAM, 25Msps Symbol Rate, 4 Points/Symbol, 2048 length) with max. BW available?As far as I have understood from the specs, the unit should have total <150Msps in that mode.So, a 100MHz BW should be feasible. However, I found a note in the specs saying that max. analysis BW is limited to 40MHzIn addition, is the unit still workable (or far too slow) in Digital Modulation Analysis with setting of 256QAM, 25Msps and 4096 meas. length?Many thanks!Rob

Please look at the marker, i would have thoght is should show the same level at a given frequency.Is there some option did i not activate?

content: Hello all!First, thanks for all the information on this forum! Very, very helpful indeed.I consider buying a SSA3032X-R or a SVA1032X and would like to hear your opinion.I really like the RT functionality and for me it's worth the additional money.According to the specifications, the 3032X-R is better on several points. TOI is better, VNA dynamic range is 90 dB vs 80 dB, the TG has 40 dB range instead of 20 dB, the digital modulation supports 25 MS/s (!) instead of 2.5MS/s. All fine.However, it also has a few (unexpected) drawbacks compared to the SVA1032X:the DANL between 1 and 10MHz is 10dB lower and the lowest RBW when using the VNA/TG 3kHz, vs 100Hz! This was mentioned before in this thread. Could someone (@Tautech ?)confirm if this is still the case?Also, the performance between 0 and 10MHz is important to me. I had a SSA3021X+ which showed ~3% EVM at 10MHz (and a lot of phase noise, I guess this was the root cause). This made the DMA far less usable to me.I wonder if the SSA3032X-R also suffers from such behavior. Did anyone check the phase noise at 10MHz?And, is there any news regarding the issue reported by the Amar87?Cheers!

content: QuoteI know, and I did study the datasheets.I have owned/used SSA3021X+/3032X+. One device showed higher phase noise and worse EVM at lower frequencies, the others were fine. So with a bit of luck, a new SVA1032X is fine as well. For all other specs and features, these instruments are really good (for me)!I have no experience with the X-R hardware, that's why I'm curious how they perform at low frequencies.The datasheet only specifies the DANL at different frequencies, phase noise is at 1GHz only.I worked with a Rigol RSA5032 so I have some experience with a comparable RT SA as well. The Rigol is fine at low freqs and has slightly better (noise) specs as the Siglent, and no remarkable rbw limitations afaik. (Howe er, I don't want a Rigol, I don't like the look and feel. It also lacks the DMA).The X-R's RBW during TG/VNA is not mentioned in the release notes (already checked these), so probably it's still the same? If so, it's a pity as this is s serious limitation imho.

This has always been a limitation in the SSA/SVA range.I'm not in front of it at the moment, but will check how RBW works in SA mode with the TG and report back.I hardly use that feature, I would use the VNA mode first.

According to spec, and indeed different from the 3021X+/3032X+/1032X.I also realized that, although the WDMA in the X-R handles a higher symbol rate, the lowest EVM that can be measured is limited by the phase noise anyway. Phase noise spec is the same for all devices and quite low..Oh, regarding front end protection: I nearly always had a 10dB attenuator screwed on the input of my analyzer, only removed it when really needed. Can recommend that...

content: I got an SSA3032X-R! Very nice, super fast compared to the non-R 3.2GHz models.Noise between 0-10 MHz is somewhat better as from hendorog. Phase noise is according to spec, depends a bit on the frequency.The unit shows strange behavior when using the 1Hz RBW filter. With no input and no pre-amp, an (almost) straight line is produced.Steps to reproduce: turn on the unit (default settings), set span to 100 Hz, set ref level to -70 dBm. The RBW is then set to 1Hz, and my unit shows an image as shown below.When some noise is applied, or the preamp is activated, a normal trace shows up. See the second image, here I measure the phase noise of a test signal. The test signal is disabled and enabled again, causing the trace to fall to a straight line for some time.I really hope (and assume) that this is a firmware issue?! Could anyone confirm this?

content: Today I found another interesting anomaly!While playing a bit with my generator I found that some additional 'static noise' appears on the left side of the spectrum, regardless of the center frequency, but depending on the span and RBW.For example, it appears in the first 20kHz on the screen when using the 300Hz RBW filter, and in the first 200kHz on the screen when using the 1kHz RBW filter.Of course it can be hardware, but I guess that this is also a software/FPGA issue... Maybe an FFT initialization/windowing effect or whatsoever.(The generator is a TinySA, by the way, and no, it's not the cause of this effect, I tried it with another source as well).

So, I'm still with 3.2.2.6.0R10.But after reading this, and having a second look at the version nr, I assume that it's safe to 'upgrade' to 3.2.2.6.2R5.

content: QuoteI'll do that, but I really hope that Siglent will fix both the 1Hz RBW and the 'static noise' problem.This forum is amazing, by the way! So much useful information... I read another thread in which user IM3 ran into the same phase noise issues as I, exchanged his unit for an 3032X-R, then reported the 'leading noise' issue as well... this was in March 2024. I assume that these issues exist since the first launch of the R-series, 5 years ago?Interesting, also because the same issues exist in the 11...12k euro SSA3075X-R.Especially the 1Hz RBW issue can't be missed ihmo, just turn it on, then reduce the span to see the noise floor...Really a pity imho, as the analyzer works like a charm, I really love it and for me it's worth the extra money, on top of the price of the SVA1032X. It is faster, the RF part is a bit better and the RTSA mode enables measurements that were impossible with a non-RTSA.The DANL at the first 10 MHz is considerably better as specified, and also compared to Hendorogs unit (seehttps://www.eevblog.com/forum/testgear/siglent-ssa3000x-r-57-5ghz-real-time-spectrum-analyzer/msg5815087/#msg5815087). I'll add a screenshot with the same settings.I had the opportunity to play some time with a Rigol RSA5032N, which is comparable to the SSA3032X-R, on paper. It has better phase noise numbers, and these are specified over the full range, even with a graph. Siglent should really do this as well! It also has nice features such as HDMI out. However... I wouldn't want to trade! I think the Rigol 'UX' is far worse. When I turned it on for the first time, I thought I broke it! It hangs in a splash screen for 2..3 minutes before it starts! Weird. The screen is super reflective, useful for combing your hair while waiting until it's up, but annoying when using it. See attached image below. Also, some interactions feel a bit strange/slow, such as changing the mode (slow!).Anyway, I'll keep checking the Siglent firmware site on a daily base for updates!

content: QuoteI have an update regarding this.The supplier of my analyzer contacted Siglent, and they asked me to try the V3.2.2.6.2R5 version from the web. They also supplied a (private) download link to the version which was in my device when I bought it (3.2.2.6.0R10), so I could revert to this version when needed.Of course I tried, and as expected (because it was confirmed by user henderog already) the problem with the 1 Hz RBW filter still exists. (Turn it on -> press 'Span' -> type '100Hz' -> press 'Amplitude' -> type '-70dBm' -> be surprised).Regarding the other issue, the 'static noise' at the beginning of the trace,there seems to be some improvement compared to 3.2.2.6.0R10this is, after some more experiments, still the same (as Tautech already mentioned). The screenshot shows less noise but was made with sligthly different settings.However, what surprised me greatly was that the screen update rate was way lower! With both versions, the sweep rate is shown on the screen as 1ms when using the default power-up settings (full span, 3 MHz RBW). However, with V3.2.2.6.2R5, the screen was updated approx. 5 times per second, where 3.2.2.6.0R10 shows a much, much higher update speed. I'd say ten times faster, or even more? I added a (zipped) movie of the screen just after power-up. The actual screen looks even faster as in the movie, the frame rate of my camera apparently interferes with the display update rate.For me, the high update frequency is one of the cool features of this analyzer. So, although some useful fixes seem to be made in the 6.2R5 (the Preset button doesn't immediately overwrite your settings!), I decided to revert to 3.2.2.6.0R10 after my tests.--> however, when testing tonight on my ADF4350 board, the SA showed a superior phase noise of -122 dBm @ 5kHz! Can't be true... I quickly realized that this was due to a bug in the SA SW... the noise marker does not work correctly in delta-mode. I saw that this problem is fixed in 3.2.2.6.2R5. So for now I'm back at 3.2.2.6.2R5, one bug fixed at the cost of a less livid display.I wonder what else am I going to run into the next months?

content: Ok, to summarize, in version 3.2.2.6.2R5 improvements are made and issues are solved (the delta noise marker now works...), but 1Hz RBW at the lowest amplitudes still fails and the strange 'noise' at the beginning of the trace still exists.And, there is a regression, the screen update rate is lower! A higher update rate helps to find rare occurences. Of course the RT mode is superior here, but its bandwidth is limited to 25 MHz.In the previous post I attached a movie from the screen directly after boot to show the update rate for 3.2.2.6.0R10. I'll add one for 3.2.2.6.2R5 as well. Both are made with the default power-on settings. See the attachments.I get the feeling that the code is mainly tested on the SSA3000X+/VNA1000X series... Hopefully there'll be another update, as this beautiful machine deserves impeccable software!

content: I just wanted to add a little teardown detail that wasn't clearly visible in the earlier board photos.My SSA3032X-R has recently developed the problem described inthis blog post and video. The price Siglent is quoting for a fix is absolutely ridiculous, so it feels like its worth at least attempting a go at it myself before sending it off to them for what's gotta be a wholesale module or unit replacement.Anyways, I do want to be 100% sure of what components are actually in the input stage of the unit before ordering them, since we've seen a few slightly different revisions of the RF board across various Siglent spectrum analyzer models. And those components aren't clearly visible in the posted photos.So I just took mine apart, and took a closeup (attached). Due to the contrast of the picture, its still not that clearly visible. So I went ahead and put it under my microscope, and took some notes:RF input is J20First IC section after the input, Z26, marked H1118 (most likely an HMC1118)Second IC section after the input, Z27 and Z28, both are marked H1118.Third IC section after the input, U132, marked 424A (most likely an HMC424ALP3E).Fortunately its exactly the part I expected to find, based in info elsewhere. But I still had to check, because you never know, and because the trigger board photos show a PE42553 switch IC being used there instead.
