That's your opinion. A clause that many might argue and disagree with. This is why the specification defines a max length of 63 characters.
(Statements like above are the opposite of a motivation for Siglent to fix it).

The scope's (unnecessary) WiFi security related limitations should not dictate how to configure security settings on your standards compliant WiFi network.
And the scope should work on any standards compliant WiFi network, not only WiFi networks that have been (mis)configured to the scope's lack of support for common WiFi standards.

My 2¢
It's accepted that a password of 8-9 characters should reasonably protect you from brute forcing at this point in time. About 20 characters should be more than enough for a thoroughly secure password. I do agree though, Siglent shouldn't limit you unnecessarily and should follow standards where applicable.

Of course, mitigating the issue could be done in more effective ways than simply slapping on a longer passphrase. Isolating the oscilloscope in its own VLAN or guest network helps you avoid potentially exposing the rest of the network. Considering how insecure the average networked equipment is, segmenting your network is not a bad idea.

My additional 2 cents:  (I'm in favor of  standards but the standard must be rational.)

IMHO, the 63-char passphrase in this case is a nonsense!

For example, even a 43-char password implies more combinations than a 256-bit key. So, it would be easier to crack the WPA-PSK 256-bit key than the 43-char passphrase (that would be used to calculate the key).

So why they chose the 63-char? Probably because, in implementation terms, they decided to allow us to insert a 64 hex_chars (256 bits) key string. So, if I have a field to insert a 64 hex_char string, why not also allow people to insert a (up to) 63 char passphrase...

That brings another question, why should we comply with something that (apparently) doesn't make sense just because somebody assigned it a "standard" status?

If anyone knows where is my thinking error, please correct me.

Mr. Scram, not knowing your background, just to make sure, you are aware that not all secrets/keys are "passwords" (sequences of fully random and independent characters), per se? And also that the effectiveness of the bits in the secret can vary depending on the use case? For example, consider the differences in the key length recommendations between AES (e.g. 256) and RSA (2048), etc. (https://en.wikipedia.org/wiki/Key_size).
So, plainly stating "8 characters should be reasonable" without considering the context might be very, very misleading.

I admit that I do not know much about the WLAN protocols etc. and thus no idea how effectively a password/secret could be brute forced in that environment.

Also note that in many secure environments, 8 or 9 character passwords are no longer considered enough. E.g. all the non-trivial hosts and systems I have access to, no matter why/who is running them (job, university, bank as a client, etc.), the requirement has been 10 or more characters for few years already. 8 should be good enough for the typical random websites/forums, though.


tv84 (and others):
I read somewhere that the 63-char passphrase limit vs. 64 char hexkey is specifically so that the same input can be used for either style; if its length is within the 8-63 characters, it is a password or a passphrase; if it its length is exactly 64 it is the hex key.

Note that "passphrase" typically does not mean the same type of content as "password"; former is often considered to allow indeed phrases (e.g. sort gibberish sentences made from real words or word like sequences), while latter is typically considered to consists of more or less independent random characters (within allowed set of characters). Thus, passphrases consisting of words/word-likes, the correlation between characters in those words reduces the entropy value of each character quite a lot. That is why passphrases should be allowed to be quite a bit longer than normal random passwords. (I'm too lazy and busy to pick up scientific estimates on passphrase entropy estimations to copy here, feel free to google...)


That said, I think it could be considered that the implementation in the scope does not fulfill WPA2-PSK spec requirements, and thus should not be considered compatible with that. And since WPA2-PSK is the last commonly used method we have left that isn't considered basically useless, there should be quite some effort to make it work correctly. Security is fragile enough even without cutting corners like limiting key field lengths :P

We all undestand what we are talking about. My final cents in this OT:

What I said was simply this: a 43-char (upper+lower+digits) pass can be more secure that any 32 8-bit symbols key.

The problem with using a common phrase it's the user's fault! No standard says to do that. Using 63-char quotes from the national anthem might be as unsafe as using the 0x00 0x01 0x02.... 0x1F binary key.

The user behavior is a big part of any security system, independently of the standards used.

Luckily not everyone has that opinion about standards, otherwise the world would consist mainly of companies like Apple and something like USB would have never existed.
"This product will PROBABLY work with your WiFi network" will not do very good as promotional banner on the outside of the box.

Your thinking error is in the fact that the passphrase on MY network is longer than 20 characters. It was longer than 20 characters long before I bought the scope and all my networked devices have no problems with it whatsoever (which includes less than $2 costing IoT devices).
And then comes a relatively pricey advanced piece of testing equipment with a shitty WiFi implementation that does not work on my WiFi network, because of a stupid non-standard passphrase length limitation of 20 characters. That's just crap.
That TP-Link USB network adapter works perfectly fine within my WiFi network, on multiple devices, but not the scope.
Every location where you might bring your scope (on the road, presentations whatever) you have no control of other people's/companies' WiFi network (passphrase). You are only allowed to use their network, not to change it!
And then you tell their network guys that standards and passphrases longer than 20 characters are nonsense. They will probably say, well that must be an old scope sorry - and laugh. ;)
That is where your thinking goes wrong.

Yes, in the last 25+ years we were taught (forced) to use complex (but relatively short) passwords/passphrases/keys (whatever). Short but complex and difficult for humans to remember.
While significantly longer ones (even when much simpler so humans can easier remember) are safer an much harder to crack.
That's why my WiFi passphrase is long but easy to remember.

Correct. But this discussion is not about user behavior but about unnecessary and non-compliant security limitations of a product (scope).
Further, the scope also shows passphrase in clear text after entered and confirmed which is real bad practice.
It feels like Siglent has taken security and WiFi standards not very serious when implementing the WiFi stack on the scope.

It is my belief that we should not be discussing personal opinions about the use of standards and well accepted security features here, while the issues I mentioned are just bugs that should be fixed by Siglent.
For me the stupid 20-char passphrase limit is a showstopper and the displaying of passphrase in clear text a serious security issue.
Your mileage may vary.

Sure, but we're not talking about RSA or similar things. We're talking about WIFI PSKs and essentially how easily they're brute forced. That's mostly what should make things more or less secure when talking about a WIFI PSK. Of course it'd be more accurate to talk about bits of entropy, but if people know what those are I probably don't need to tell them anything about it. Anyone who has "sunshine" or "123456789" for a password and thinks that's enough is asking for a lesson. It's not 1999 any more.

Also note that 8-9 characters is the current bare minimum. Having a 10 character requirement only seems sensible as a precaution. Of course, what the real world requires you to have isn't a good representation of what makes an effective password. For years we've been taught or forced to do things which turn out to be rather ineffective. Currently the world is shifting from single passwords to more sophisticated schemes like 2FA and conditional access. Especially the latter seems to give passwords a new lease of life, though it's generally accepted they're bound to disappear sooner or later. Like I said last time, the user also has things in his own hands if he applies network segmentation. Ensure the device can only talk to the parts of the network you want it to talk to and the PSK suddenly isn't as important as it would be otherwise. If one worries about 20 characters being enough, that shouldn't anything new.

Again, I do agree that Siglent would best adhere to existing standards.

On security matters, standards are sacred, period.

What is not a problem right now can become a serious issue in an hour. Moreover, lack of respect for standards makes security harder to implement, which usually leads to sloppy practices.

So, no excuses. Siglent, do your job as soon as possible. These kind of mistakes are tickling time bombs. The tickling is deafening.

Well, I recently ordered a Rigol MSO1104Z but after detailed reading and spending a few hours using what I would describe as the most sluggish UI I have ever dealt with on an instrument I'm not convinced it's going to hang around.  I ordered a Siglent 1104X-E to try it out and see if I like it better.  I REALLY like that 4 channels at 500Ms/sec is possible and that it has higher waveform update rate as well.  I've read there however some serious issues with the MSO portion of it, or at least there were.  I've tried to read through this thread but I was wondering if there is a list of outstanding bugs that are still out there? 

Has the MSO/LA improved any?  That's a big feature to me and I have every intention of upgrading to it if it is not crippled. 

Are there any big show-stopper bugs still out there?

I have to say, purely on the look/feel of the UI and front panel I prefer the Rigol1000Z series, but once you step past the $360 price point the SIGLENT seems like better overall performance match to a 100Mhz (200 if I feel adventurous) scope.  If I am going to sell off my Rigol DS2202 I don't think I can really live with the RIGOL 1104Z's terrible sluggish response.  It feels like crap switching between the two.  If the SIGLENT is snappier then it's inexpensive enough to consider hanging onto my DS2202 as well.  I love that scope but I always wanted 4 channels but they were astronomical in the day.

Not as far as I know. There has been a firmware update for SLA1016 a few months ago.

Understandable as you're well used to the GUI/UI.
Like any instrument, let the operation of it take a little while to get used to you  :)  ;) and in no time you'll be able to switch between them without a second thought....sure that's harder if you use them infrequently.

Hey thanks for the welcome!

My last point is really aimed at the Rigol MSO1104Z vs the Rigol DS2202.  The UI is really consistent actually, menus are easy because they work just alike on the two and frankly if the 1104Z had snappy response I likely wouldn't be looking around, but I was very disappointed with the UI speed on the Rigol 1104Z.  On the 2202 things move very quickly and the markers move and then the trace is right behind it.  On the 1104Z (Rigol) the trace sort of lumbers it's way towards and then past what you wanted and then the marker moves once you stop turning.   Similar with changing the V/div setting very easy to roll past what you want with no screen update till you stop turning.  The waveform zoom function is painful when you scroll horizontally.

I don't want to get used to that.  I didn't notice it that bad in the video demos but often you get fixated on the screen.  Now that I re-watch them I do notice it in the videos too.  It sure looks like the SIGLENT is much better in this regard.  If I can get 200Mhz unlocked then it may be a good replacement for my old 2202, both in channels and bandwidth.  I should have it this weekend to try out and decide.   Somebody has to go back and I *suspect* it will be the Rigol.  I'm only really torn about the MSO option right now.

Thanks!

I was just finding the excellent review thread and spotted you were already reading it.  :)
https://www.eevblog.com/forum/testgear/siglent-sds1104x-e-in-depth-review/

Like so many of the longer threads the 'real meat' of the advances and features fixed/added are near the front and end of threads so you just have to spend a little time doing the research.

I also have a big list of all the SDS X-E (according to the code) but I can't find it now...  |O

Your "DMES" is DMESG (similar as in unix).

Tautech, any input on why half these commands are not documented in the manuals?

As I browse through them most appear to be the equivalents of UI functions, ie. available within the user menus and sub-menus.
Some are specific to options and external connections however there's no doubt others will be factory configuration commands.

On the 1104Z (Rigol) the trace sort of lumbers it's way towards and then past what you wanted and then the marker moves once you stop turning.
frankly if the 1104Z had snappy response I likely wouldn't be looking around, but I was very disappointed with the UI speed on the Rigol 1104Z.

It's only really the vertical movement that's slow and a lot of the problem can be mitigated by technique. I made a video a while back:

Re: Siglent SDS1104X-E and SDS1204X-E Mixed Signal Oscilloscopes
« Reply #1070 on: December 03, 2018, 08:20:30 am »
Has the MSO/LA improved any?  That's a big feature to me and I have every intention of upgrading to it if it is not crippled. 

Are there any big show-stopper bugs still out there?
The integration of the MSO option with the SDS1004X-E DSO is not great, so you can call it crippled indeed, when compared to the fully integrated solutions in SDS1000X+ and SDS2000X.

Last time I've checked it about 9 months ago, there has been some 7ns skew between analog and digital channels and the digital deskew parameter was not preserved upon a power cycle. I expect this bug to be fixed by now though.

Mixed channel Pattern Trigger is not supported, so it has to be either an analog or digital pattern.

Furthermore, both History and Zoom don't work when digital channels are enabled. Since most people want the MSO for decoding serial buses nowadays, this means you cannot decode long messages, because the decoder line at the bottom of the screen will become unreadable due to the lack of space. Using analog channels, you can easily deal with that by just entering zoom mode and take a closer look at the part of the message you're interested in. As it is now, when using digital channels you're almost limited to the capabilities of a Rigol 1000Z which only decodes the screen buffer anyway

The limitation described above only applies in run mode though. You can still capture a long message and then zoom in and navigate through the message while in stop mode. Also the list view works during Run even for very long messages, but that's rather pointless as you cannot closely examine the corresponding waveform – you might just as well use an LA instead.

Other than that, it's not all that bad. Here is an example how a 100MHz SDS1104X-E is capable of capturing a 320MHz sinewave with only 1.5Vpp amplitude on a logic channel of the SLA1016:


SLA1016_D12_Sine_320MHz_1.5Vpp

A 4ns wide pulse – heavily distorted when viewed on the analog channel at just 100MHz bandwidth, but nicely captured on the digital channel:


SLA1016_AD_Pulse_5V_4ns_probe

16 digital channels, grouped into 2 parallel buses, captured at 1GSa/s with 14Mpts record length. This also demonstrates how the decoded values become unreadable in the busy regions, where we get just blue bars. In stop mode, zooming into these regions wouldn't be a problem though. I just don't happen to have a screenshot at hand for that.


SLA1016_Bus_Select

Finally a digital pattern trigger. Two buses again, the first (lower) one decoded binary, the 2nd (upper) one decimal:


SLA1016_Trig_Pattern_1us

Thanks!  That's helpful to know.

I'll probably go ahead and get the LA later on next year.  It's not a show stopping thing for me not to have it, just something that I would like to have.  Looks like for the things I would typically like to use it for it would work though that lack of decode in a zoom is a bummer.  I appreciate the insights!


So I've processed the return for the Rigol MSO1104Z.  Just not what I wanted for a scope that cost about $800.  I'm not a Rigol hater, I have loved my 2202 and I like aspects of Rigol's interface better but they just did not impress me with the 1104Z.  After unboxing and playing with the SIGLENT and trying out the web server interface that is WAY more responsive and useful than the windows-only UltraVision stuff, it was an easy choice for me.  Glad I learned about this option here before return time ran out.

There are things like how to make the scope enter bode plot mode with certain parameters that is still unclear to me.

Sorry, when I said I had it, was in my home... somewhere. Not in the forum.

I'll try to compile something again.

But I don't refer to the specific parameters. Only the commands.

Of course if you have any specific command it can be analysed with more detail in the code to try understand its parameters.

Is there any facility to change the labels of the channels?  I didn't see it in the manual or playing arounds in the UI, so my guess is there isn't but thought I would confirms that.  That'll be something I miss a little bit.
