This looks like a neat tool but what I'm missing from the specification are the input capacitance & impedance. And the capture buffer is quite small. 128Mbit in total (14Mbit per channel for the 9 bit version and 7Mbit/channel for the 18 bit version).

Yes, the capture buffer is quite small. But as with many USB logic analyzers, only transitions are stored (often referred to as compression). They claim 100M transitions can be captured in most cases. This can be tested here:
https://tech-tools.com/captures.html

But still - YMMV.
One should always consider data sheets and specs carefully.
Corner cases and unlucky circumstances are always lurking and waiting to ruin your day.

In this regard I think the boat anchors are a safer bet - I think they have fewer "hidden" limitations and surprises.
But then again - the DigiView is a lot smaller than the floppy drive of a boat anchor :)
Yes and no. Typically I'd agree a boat anchor takes a lot of space and is a PITA to haul around the lab but the Tektronix TLA700 series is an exception. My TLA715 sits high up a shelve and I control it remotely from my PC. The probe cables are long enough to reach the desk below so basically I only have a few probe pods on my desk when using the logic analyser.


Does this mean we can control full logic analyzer functionality through a PC software without interacting with its display and controls?

One more thing, which modules do you recommend for this unit? My main application is FPGA development and that can also occasionally involve debugging serial communication protocols like pciexpress/MPI/etc.

I was not aware of this device, it looks quite capable for the price, does its windows application show captured data in real time fashion or you have to wait the end of recording phase ?
It operates in the normal capture-process-display manner, with "Auto Run" or "Run Once" options on separate buttons. This can be fast or slow depending on sample speed, memory depth, number of signals and decoders, see under Performance section here:
https://tech-tools.com/digiview-sw.html

The software also has Search on captured data. I haven't used it, but it seems comprehensive:
https://tech-tools.com/searching.html

Overall the software is a bit unusual and takes some getting used to, but it's always responsive and stable. Never seen a crash.

BTW, I think this analyzer is a bit slow for the OP's applications.
And a bit expensive ::)

Does the "Auto Run" mode act like a DSO "normal" trigger mode, so it auto re-arm after serving a trigger event ?

Considering its capability to define complex trigger / capture mechanism by a script plus graphical scheme it does not seem so expensive.

DSLogic Analyzers have stage trigger supporting 16 stages of trigger flag. Each stage support logic operation (and/or) of 2 sets of trigger. Each set support edge/level trigger of all channels, invert and counter. There is also serial trigger - https://www.dreamsourcelab.com/doc/DSView_User_Guide.pdf. It does not look much convenient to set up, but it seems possible to filter the requested from you values ?

Serial trigger does not work at all with async serial and it's a huge pita to setup with I2C and SPI, stay away this thing if serial decoding is your job.

Mine is in transit and can not test it right now. Have you tried submitting a support request via Github - https://github.com/DreamSourceLab/DSView/issues ?

Not yet, but I guess that it would not bring anywhere considering the way they implemented the whole mechanism, where an actual signal transition is needed to define a data bit position.

So it's easy to understand why only I2C and SPI are supported, in any case the system implemented to define an advanced trigger is a huge pita to say the least.
In my case the final nail in the coffin is the following "feature" : during the capture process DSView shows a progress round graph that drives you crazy in auto repeat mode rendering almost a flashing screen  :palm:

So, if async serial trigger OR live screen update are a must for you prepare a place on a shelf to store the toy (like i did).

Yes. The application software that runs on the analyser itself does the same.

I know too little about the serial protocol modules to answer this question. I never really looked into obtaining one of those.

There are two independent parts to that: the physical layer hardware and the decoding.

To me, Message Passing Interface is a software concept, and at that point printf() statements are conceivable. OTOH pciexpress is a physical and PHY layer concept.
There are lies, damned lies, statistics - and ADC/DAC specs.

The progress round graph is really very annoying. I have already submitted a support request to be removed. It would be much nicer if there is continuous acquisition. Regarding the other issues will look at them too.

From the inexpensive USB logic analyzers, DSLogic series seems to be the most advanced. Presume  with time the software will improve. DSView is open source and hope more developers to get involved and improve it.

Yes. And "Run Once" is like "Single" on a DSO.

Good, do you have an idea about re-arm time ?

I know that it's for sure dependent on capture settings, I need a rough number to understand how much the system is responsive.

This thing is so wrong that could lead to think that no one is really using this tool for real job, how is it possible that no one is crying about that ?

One of the lesson learned in my life is the following : never rely in a open source development for serious things.

My current feeling for my DSLogic plus purchase is that I threw out the window 130 euros, but as we all know sh*t happens.

I like many open source tools. Embedded Artist LabTool https://www.embeddedartists.com/products/labtool/ is not bad, but EA stopped developing further the software. The logic analyzer works fine, but has very basic capabilities. Some of the stuff – size of the windows, signals, colors can be changed via the source code. I like the idea that a product can be changed from the user. Also the interaction with the developers, other users, meeting and discussing issues with other people. A person can purchase an old huge 30+ kg. logic analyzer that works somehow and can not change anything … and where is the fun with that ?

I really hope DSView will improve. There is one saying if something ends badly, this in not the end.

You pay for experience with your money and/or time.

Closed source commercial products are clearly the way forward. I recommend you spend time considering Microsoft Plays For Sure, Microsofts many GUI/Web frameworks (e.g. silverlight), Altium CircuitStudio(?), Micro-Cap simulator, Adobe Flash etc etc etc

Hint: there are no real general distinctions between open source and commercial products, but each product has its own relative advantages and disadvantages. It takes hard-won wisdom to choose.

Anchor boats are far to be of my interest, old LA in particular, they have ridiculous performance in rapport of current standards.

I really hope DSView will improve. There is one saying if something ends bad, this in not the end.

I hope to be wrong, but being the project out from many years and given the importance of current shortcomings the chances to see them solved in reasonable time (weeks, months ?) seem close to zero.

Dunno if you have ever used Pulseview, with all the respect for developers group it could be good for a newbie in conjunction with 10 dollars Cypress 8Ch LA dongle, for a professional is a joke.

Agreed. Both commercial and open source software can be excellent or suck badly. You can't tell before you investigate a particular piece of software.

Commercial products have to satisfy many requirements, if the commercial company fails in that lose customers confidence and go bankrupt, open source projects often are simply training ground for budding programmers.

Sorry, but you are wrong here. There are lots of examples of good open source software. Keep in mind that commercial parties do work on open source software to basically join forces without needing specific agreements to do so. Kicad is one of those examples but there are many more.

I said "often", not "always", IMHO Kicad is the only open source tool usable with profit (as I do for small PCBs), otherwise I have more positive examples for HAM radio SDR application than professional electronics.

Are you a keen / proud open source developer / supporter ?

Remaining in thread, do you have an example of open source LA SW / HW system that is barely comparable to a professional product ?

The initial release of KiCad was published in 1992 or 31 years ago. In comparison the stable release of libsigrok was released about 3 years ago. Some claim that the sigrok main developer abandoned the project, but as far as I am aware other continue to developing it. There is much more to be desired in terms of capabilities and it takes time and devotion. The main issues with logic analyzers probably is that the advance triggering and filtering suppose to be performed on the accusation module presumably on the FPGA or MCU. In other words, such project suppose to developed the device firmware as well. This might be an issues in most of the cases. Currently, an interesting implementation is sigrok-pico https://github.com/pico-coder/sigrok-pico. It is my understanding that can achieve 250 MHz sampling rate. For 6 USD (WiFi edition) I would say, it is quite an achievement, still there there is lots of work to be done about the WiFi connectivity as well as how this logic analyzer works as whole.

As you said, Trigger / Conditional Capture are the aspects where Sigrok fails to satisfy any even barely serious demand.

HW wise you have no input protections and no variable thresholds, software wise you have basic (to say the least) selectable trigger mechanism (rising/falling edges, advanced ones are in another world).

Dunno if this specific branch goes beyond "standard" Pulseview in any aspect, but if I go to its Github page I read :

At this time my pull request into the main sigrok repo has not been accepted.
Thus mainline releases of sigrok cli and pulseview do not support this repo.

 
so, for instance,  you can forget to try it under Windows with an official binary release, you want to venture out in Windows compile process (good luck).
 
As I said, for a newbie / hobby works  those are great tools almost for free, but we are far from something that is remotely comparable to professional ones.

My understanding about DSLogic LAs is that they are mainly used by hackers to trap external memory access in order to exploit application protection mechanisms.

I am neither religious nor political. I look for tools that are fit for purpose, easy to use, and do what I need. Sometimes those are free as in beer, sometimes free as in air, sometimes extremely expensive.

All that implies understanding why different types of tool exist, their relative advantages and disadvantages - and not falling into ideological ruts. And also using whatever is available creatively and to best advantage.

Everything in my .sig is there for a reason.

Good, do you have an idea about re-arm time ?

I know that it's for sure dependent on capture settings, I need a rough number to understand how much the system is responsive.

It will depend on a lot of things, including the computer it is running on.
But with short capture memory I get tens of updates per second (20-50 updates per second? Not sure).
Similar to my Analog Discovery 2, signals seems to update pretty much instantaneous, without any annoying delay.
And a slow-ish FM signal looks like a spring compressing and extending.
Seems responsive enough for me, no complaints here.

That seems great, this device is not cheap but seems to carry everything is needed for serious job.

Noted for future need.

For boat anchor logic analyzer fans, you can sometimes find reasonable deals if you are patient. The last boat anchor logic analyzer I picked up around 3 months ago was an Agilent 16902A, which included a 16910A 102-channel 32M-sample analyzer module (plus a couple of other modules) for a total of $200 including shipping in the US. This deal was probably better due to the 16902A lacking a hard drive, which was easy for me to replace and reload the OS and application software, as that is something I had already been through a few times.

The Agilent / Keysight 16900 and 16800 series logic analyzers run Windows XP (or Windows 7 in the much nicer and faster newer versions), and can be remotely controlled by the logic analyzer application running on a remote PC. In some cases the remote control might provide a better user experience if the logic analyzer application runs on a significantly faster modern system than locally on the 1GHz PIII motherboard built into the original 16900 series logic analyzers.

In Europe they are more expensive. For example, currently in Germany there is one listing for HP 16500C (https://www.ebay-kleinanzeigen.de/s-anzeige/hp-16500c-logikanalysator-incl-erw-karten-und-sehr-viel-zubehoer/2245980136-168-4201) - 350 EUR. It includes the following modules:

HP 16555A: Logic Analyzer, 500MHz, 64 ch, 2M-deep/channel
HP 16533A: Oscilloscope, 1GS/s, 2 ch
HP 16517A: Logic Analyze, 4GHz, 16 ch
HP 16552A: Pattern Generator, 200MHz, 20 ch (40 ch / 100MHz)

+ lots of cables and adapters

Just the shipping in Germany cost between 50-100 USD. If it has to be delivered to another EU country will cost probably at least another 100 EUR.

Any comments about the quality of the oscilloscope ?
