If they are going to keep making these instruments taller and slimmer to get the nice big screens most of us prefer, maybe they need to start thinking of instrument design more like monitor design. It looks like this instrument has little flip out feet to make is more stable, but that's a pretty weak solution. It looks like pressing the uppermost buttons is going to be pretty annoying.

Somebody with experience please compare real time (fft based) and standard (heterodyne sweep type) spectrum Analyzers in terms of accuracy?

IMHO it would make more sense to come up with a 'cheap' network analyser.

The price is most agreeable ;D
Seriously, though, has anyone seen actual prices somewhere?
-
I think they are still loading the data into the website.
Prices for EU (US?) are not defined yet, looking at the products I would say between euro 5000 to 15000 (basic 3.2 to full opt 6.5) but this is a guess only.
We will all know more around end of January.

We have tried the beta unit at the beginning of the year in China during the introduction of the new chipset, the unit seemed to be pretty stable (it is touch screen). The unit weights almost 5kg.

Why does it give a complex trace without any input plugged in ?
have they got that young lady from Tek to give her opinion on it ?

Sorry, I'm bored....................................................

It will all be up to the VSA SW they will offer. Once you have those 40 MHz of real time BW it is all down to what you can do with it, how you can present and process that data. So we should be looking for WiFi, LTE, Bluetooth, Pulse(Radar), FDD demodulation etc. Until those are presented and reviewed, it is more or less useless, it makes nice screenshots :-DMM
The only really good VSA SW is still the Keysight VSA. TEK is doing good work in that region with their VSA SW, but still it is far from being as robust and reliable as the Keysight tools.

I hope, Rigol will send one unit to Shahriar from The Signal Path so he can do a review on it.
I always appreciate his reviews on testgear. :) :-+

Ah, the great car comparison. Anyone with an expensive hobby knows this one. Tell people how much your <insert expensive tool used for your hobby> costs and the commonest response is "I could buy a used car for that". :)

It doesn't make it any less true :( I wish I could afford all that gear, as I definitely have uses for it, but for now I have to improvise.

The fun part is that cars can be bought for almost any amount, in varying states of disrepair. Saying "you could buy a car for that" is as valid for a $100 piece of kit as it is for something costing a million bucks.

So let's continue in the same tone:
Repeat after me : " we need to solder capacitors to the board too.. It seems that you cannot do that in firmware update... and stupid users are bothering us about this.. lets just send them some in mail, they can solder them themselves if it so important to them, them spoiled brats.."
What do you call that, Siglentcastrophy ? Siglentmagedon? LOL.
I usually enjoy your quality contributions to the forum, good information about Siglent equipment, and your help to many forum users. It is appreciated and is something to be proud of.. I respect that.
But this, seriously, don't get offended, but this was a bad form and in this topic nothing called for it.
Also, that very user that coined that phrase, is the one that is known for racist, xenophobic, sinophobic, homophobic and all kinds of hate statements on this forum.. And don't you worry, the hates your "Chinese shit Siglent" with same passion.... And probably you for "peddling that Chinese shit "
P.S. unfortunately, my sense of humor is not very good, and not for the lack of trying.. I tried to strike a humorous note.. I probably failed, sorry..

Many people suggest there is a clear gap between Chinese and EU/US brands in terms of quality. I think it's proven many times this is just wrong. No vendor is ideal, all major manufacturers do mistakes. One may say western companies handle problems "differently", but I'd say there is a big variation from case-to-case basis. Srsly, how problems with jitter on a 4-5-years old model can be used to extrapolate on yet-unrelease gear?
So, for me no matter where the new product comes from, only thorough reviews and can show the quality (still no protection from bad batches). So, I don't look at labels anymore, it is quite pointless nowdays (esp. with all that rebranding stuff when western companies just sell rebaged good).
Also, it looks like Chinese companies are catching up with more established brands. Let's see the market situation in 10 years...

Currently, the main difference seems to be the way problems are handled indeed. According to some of the Chinese members here, the idea of building a reputation isn't natural to many Chinese manufacturers.
That being said, I've purchased two devices made by GW-Instek and have been very suprised by their solid build quality. I know they're Taiwanese and not actually Chinese, but you get the idea.

Is that three front panel USB ports, a headphone jack and a vent for an electret microphone? Or maybe that's a vent for a beeper/buzzer? Why three USB ports... and a headphone jack?
If it IS a microphone, could this be the world's first voice-controlled spectrum analyzer? :-DD

Well, let me put it this way: hardware wise, quality is just fine. It is very good in comparison, with many recent flops from big brands, trying to compete in (to their perception) low margin part of market.
On software side, on the other hand, is a lot of room for improvement.
Problems range from software that is clumsily design (be it user interface or choice of options), generally lacking features, to simple implementation problems. All in all, functional but far from polished, easy to use and quick to accomplish tasks.. And firmware side is not worst. I personally find most Rigol products I tried, is to be honest devices that work quite well, but their PC software is simply useless...
Siglent seems to create good platforms, but rushes them to market half finished (hardware and software) and has reputation to abandon devices too soon, moving on to new ones..
I in that regard, I find Rigol to be more professional. On the other hand Siglent approach will in theory more capable device, if you're willing to wait for a year to iron out basic operation..
And I don't think 10 years.. I think it is starting this year. RIGOL's new series of RT spec analysers mentioned here are start, new series of scope based on their new chipset etc...
If they gonna attack mid range they will have to become competitive on look and feel and software side.. And support..
And they will.. And it will be interesting..

The software side of things often is horrible even in very expensive equipment. Dave's review of a logic analyser showed this in some detail and that's not by any means an exception.

Mouse + keyboard + USB stick would be my guess, Wifi-dongle possibly, provide power and possibly control to some external device perhaps. The headphone jack is most likely for audio-output (demodulated RF signal). No idea what the mic would be for. Voice Control is one option, might be the first spectrum analyzer but not the first piece of T&M gear.

Very mature and professional approach from a distributor of a compeeting brand.
Everyone here knows you prefer Siglent but comments like that just makes you look like an idiot in my Eyes (and I know from your regular forum posts that you're not). I don't remember seeing comments like that from "representatives" of ANY other brands than Siglent and that simply does NOT help you or the brand you're trying push. Representatives from Tek, R&S, Keysight etc tend to be a bit more professional and either stick to facts or keep their mouth shut when they simply have nothing constructive to say - you should try that next time.

I hear you. But big brands are also not always good from start. Check this, for example: https://www.eevblog.com/forum/testgear/e36300-series-programmable-dc-power-supplies-(e36311a-e36312a-e36313a)/ (https://www.eevblog.com/forum/testgear/e36300-series-programmable-dc-power-supplies-(e36311a-e36312a-e36313a)/) . Big standby power consumpion, random hangs, fun turns on even if unit is not switched on, current limiting is not accurate ([1]). And that's an expensive device recently released (still haven't seen issues addressed). If it was Rigol that thread would be full of hate.

Representatives from Tektronix just make spammy posts, which is a lot more professional than this.

Well I mentioned that but didn't elaborate... Let's see : there was many Keysight 2000/3000 scopes with NAND rot that stopped booting. There is known issue with Keysight scopes blowing PSU-s...
A member here saying that his TTi lab PSU (that he bought it just for that purpose to be a good brand just in case) damaged 10000 USD development board. It was set to zero on power up, the switch on spike reached 10 A..
Much overhyped R&S RTB2000 full of bugs, expensive, and people bought it without being released yet... Etc Etc...
Most of users of brand name equipment wont even tell you it never breaks, they tell you they have great support when it does...
I don't worship any manufacturer, and none of them are perfect, not even close.
I predict that USA corporations, hungry for only high profit margin industry, will at one moment start pulling out of R&D industry at lover spectrum completely. Like IBM, that kept consulting and only mainframe and Power servers hardware. They sold everything else..

Update folks!
There is now datasheets, users guide, programmer's guide, etc., even pricing on Rigol's international site:
https://int.rigolna.com/products/spectrum-analyzers/rsa5000/
Also several introductory videos showing it in action are posted.
Quick screen shot of pricing attached.
Perhaps we'll start to see some demos and comparison against Siglent SSA3032X?
-
European Pricing:
RSA5032 EURO 6895.-NET
RSA5032-TG EURO 7895.-NET
RSA5065 EURO 8595.-NET
RSA5065-TG EURO 9595.-NET

Why does it give a complex trace without any input plugged in ?
Maybe this amazing product shot from their European site gives a clue. There's some serious parallax going on here...

So, perhaps more just a general question about RTSA... I saw PvT mode, power vs. time, and wonder what is the time scale referenced to?
If I set a 1s acquisition time, I presume there will be a 1s sweep, but what triggers it? Does it just free-run?
Also, they list Frequency Response: <0.5dB. what does it mean?
-
from the user manual:
Scale/Div (PvT)
Sets the unit per division in the vertical axis of the PvT view. Note that this menu is only valid in PvT measurement mode.

Don't worry, it looks fixed. I was talking about the original mistakes. I can come up with various amusing scenarios that would result in something like that.
Points for the quick fix, though. It tells me Rigol is interested in catching and improving upon mistakes.

Although this thread was the first focusing on RSA5000 -- or second if you count the much older thread (https://www.eevblog.com/forum/testgear/rigol-announces-phoenix-chipset-and-ultravision-ii-technology-platform/ (https://www.eevblog.com/forum/testgear/rigol-announces-phoenix-chipset-and-ultravision-ii-technology-platform/)) -- there is (unfortunately) a lot of useless posts here.

Has anyone else tried a Rigol 5065-TG?
I had a demo unit, I did a SAVE "Screen Image", Rigol emailed me back that this is not a bug... |O
The bmp files have a pop up on one, and on the other one a keyboard over the data, I converted them to jpg to post here
Now I found how to put up a Poll
https://www.eevblog.com/forum/beginners/rigol-5065-tg-save-image-function/new/#new (https://www.eevblog.com/forum/beginners/rigol-5065-tg-save-image-function/new/#new)
-
How the hell can they miss this? And why BMP as screendumps? This doesn't bode very well for the new Rigol DS7000 oscilloscope.
-
The save image can be bmp jpg or png.
There is also a Save Measurement for the 801 points of data across the Span.
-
I was wondering why there isn't a save option where you can only capture the actual graph?
The save is an actual screenshot. Fair enough.
But there should also be a save for the actual graph, as now you will have to cut it out from the graph manually when you put it in a formal report.
-
Yes, true, but the data I need is behind the keyboard...
