content: Just announced today (I think)https://www.saleae.com/Looks like there are four new models in the lineup, all combined digital/analog. It's only pre-order for now.Logic 4: $991 digital/analog input3 digital only12 MS/s digital6 MS/s analogLogic 8: $1998 digital/analog inputs100 MS/s digital10 MS/s analogLogic Pro 8: $3998 digital/analog inputs500 MS/s digital50 MS/s analogLogic Pro 16: $49916 digital/analog inputs500 MS/s digital50 MS/s analogLooks like the Pro 8 and 16 could replace a low end mixed signal DSO for <5 MHz low voltage (-10 to 10v) signals, and I like the looks of the $100 Logic 4 for basic work.I wonder how their software will handle triggering on the analog signals. And it would be a really good idea now that they have analog input to implement a real time view feature in their software, rather than the capture, view, rinse&repeat process of the current setup.

content: Analog Triggers are going to be part of the release, yes.Also, real time view is on the way, but won't make it into the release. Vote it up!http://ideas.saleae.comAnd no, the new Logic is not exactly an oscilloscope replacement. We *may* be thinking about doing that later.Here's what you can not do with Logic's analog capability:High VoltagesReally small signals (<100mV) at high resolutionReally fast analog signals (over the rated bandwidth, which is 600kHz, 1MHz, or 5MHz depending on model)Measure signal integrity on fast digital edgesRFEye DiagramHere's what you can do:All low-medium bandwidth, low-voltage analogAnalog sensorsDAC/ADC/PWM->AnalogOp-amp circuits, classic analog circuitsData loggingPower rail monitoringAudioControl systemsetc.I've probably left a few things out, of both sides of the ledger. Let me know!-Joe (Saleae Co-Founder)

content: I'm not sure it is different enough to warrant the price difference between the analog discovery. With the projected 10 ENOB @ +-10V, that's 20mV per step which is really quite poor for analog/audio work; I see no mention of range switching? I was really looking forward to this (I guessed what it was after reading the email that something new was coming), but I am underwhelmed with the lack of fine voltage resolution. Makes it more of a toy than an instrument for mePerhaps I will make my own 16 channel analog frontend....And for the record: I absolutely love my saleae logic, had it for a long time, and recommended to a colleague that he buy a big boxful of them for our EE students (which he promptly did). IF this device fits your needs, saleae is definitely a company that deserves your money.

I seem to have failed at making that point. my bad. My intent was not to make it sound like the LP was better but was better at sample rate and had more channels. The saleae seems to be better on everything else. +2 for MAC I missed that.

Its weird how many people complain about bonus features (which are analog functions truly are in LA).I'm thinking about getting Pro 8 as sometimes its really nice to carry small box which can do MCU debugging on serial buses just like 20kg Tek. Yes, price is little high, but hey, it can save countless days of debugging for digital folks.

I also have an original Salae and an Intronix, but neither is ideal.Is there a fast, buffering, FPGA based logic analyzer with computer support out there?

content: Quote from: TiN on April 08, 2014, 03:23:42 pmIt's not weird that people complain about "bonus" (?) features if they don't work well and add significantly to the cost. And measuring switching noise on digital lines sounds like it's exactly what I'd want to do with this thing, especially since you can trigger analog capture from a digital signal & vice versa. But I think the analog specs fall short of making it really useful. (I have a Saleae Logic and I think it's great as a cheap low-end LA.)

Like the Arduino and Raspberry Pi crowd who just might happen to deal with some analog light/temperature/whatever sensor they got from Sparkfun/Adafruit from time to time. And don't get me wrong, I don't mean that in the derogatory way. I don't see it being marketed as a serious low-level engineeringtoolfeature.

content: Zapta: Yes, the new software will work with Logic and Logic16. (the 1st gen products)os49la: Regarding the Intronix, I think the main issue is the sample depth. Streaming over USB is a big tradeoff – but one we’ve decided to make to support long captures. That said, I'm sure for some people the Intronix is the right choice.Jeremy: Your comments are well taken, thank you. I love your comment about “Saleae Logic” – me too. ENOB is a measure of AC performance – noise and distortion – it can’t be converted to mV of resolution.http://www.analog.com/library/analogdialogue/archives/47-02/RAQ_90.htmlAmyk: Logic 4 combines 4 bits of digital with 8-bits of analog using a cool latching latching setup. The device sends 96MB/s to your computer. We could have pushed the limits more, but we never want to have people see that “sorry but Logic couldn't keep up” message you sometimes get with Logic (Gen 1). “It just works” is super important to me.Mojo-chan, Len: I think the major value proposition is that you can record – like a data logger. Noise / switch-mode power supply emissions - not recommended. I’m sorry it’s not a better fit for you!Theatrus: how fast do you need?

content: Quote from: JoeGarrison on April 08, 2014, 08:03:35 pmYea I agree. However you seem to have got the new Saleae up to an impressive speed when you switched to USB3. It is not that far off from the Intronix as far as speed goes.For Future firmware updates:1. Would it be possible to have the PRO16 have a feature to switch from extended memory (USB3 streaming) to faster speed (FPGA memory capture) . That would be one more nail in the coffin for the LP.2. Another good feature would be to give it the ability to do Timing mode or State mode capabilityThat said. My only problem is that I have to up my budget from $389 to $499.

One doesn't exclude the other.You mention USB streaming as a 'big tradeoff' you made. But it has huge benefits. Just as the high speed, width, and triggering flexibility of the Intronix has big benefits. But with its own constraints that result.It's unrealistic to expect a single (inexpensive) tool to be the best fit for all situations. You can have it super Fast. You can have it super Deep. You can have it Affordable.Picktwo.

I almost lived with that until I contacted them with a few questions and their attitude was we don't want you as a customer (because I was asking them questions). In the end I decided not to go with their product because of the sample memory, their attitude towards a prospective customer, and also that their software is closed (you can't add or develop anything to add to it).I ordered a Logic16 from Saleae and I am completely pleased. Not only did they have a good attitude before the sale, but they have had a tremendous attitude after the sale despite me knowing they have been busy with their new launch. Now knowing that I don't have to worry about buffer length or mess with extensive triggering to overcome the limited buffer length, that I can make any decoder I want or need to, and the way they treat their customers, it is so past a no brainer which one to go with that I can't say it enough. I really like and support companies that take care of their customers - it makes all the difference. I wish Saleae the best success in their new offerings.

content: Mojo-chan: It might be a bit niche, we’re not sure yet. It’s kind of a new category of device. The use cases probably overlap with National Instruments to some extent, but maybe more for debugging than for data collection. We’re going to add a bunch of use cases to the website as soon as possible, because you’re quite right, it’s not immediately obvious – I think because this capability is basically not existed before. Some examples are ADC/DAC (low speed microcontroller stuff); PWM->Analog, control systems, audio (and I don’t mean 24-bit audio, just ‘is it working’ audio), power supply voltages & sequencing, analog sensors, op-amp circuits, data logging, etc. Btw we have 8-bit, 10-bit and 12-bit models.Abyrvalg: Sorry, I miss-spoke, that’s 96Mbit/s not MB/s.Mark_O: Thanks for the comments, much appreciatedLeafi: Thanks for being a Logic16 customer, awesome!Alank2: Thanks a ton, it means a lot.

content: Quote from: JoeGarrison on April 10, 2014, 04:12:27 amIt's stuff like this.... You see the price of a Saleae and think, ohhh, that's a little high... But the hardware, software, and everything I've ever seen about the company is covered in awesome-sauce, breaded, baked at 400F, then comes out piping hot and delicious and otherwise just so incredibly wonderful that I'm genuinelyproudto own a Logic myself. I know, I'm gushing, but that little $100 box is one of my favorite gadgets. Even the probes are pretty great. I've recently started using them for other stuff, so I'm thinking I may need to order a few more just to have around. (I don't know whose silly idea it was to make gray the ground lead though. What is that all about?)Having analog input would be great for those times when I kinda need a scope but don't really need 1Gs/s, and would also like to be able to see the waveform on a real monitor instead of a low-res LCD. It kinda hurts to pay as much for that as a I did for a DS1102E, but ... I think if I got one, I would still get warm fuzzy feelings about itafterthe check was signed (virtually speaking that is.) If the thing could play back and/or generate signals, it would be a done deal.As for the software: I also hate the zoom, so I'm glad that's being jettisoned. It's cute and all, but it's not useful and often moves the display around in ways that can make it easy to lose your place. Otherwise, the software is simple, elegant, and just works. Right out of the box, I was troubleshooting a timing issue with an RGB LED matrix and I had the problem nailed in less than an hour after plugging it in for the first time. I particularly appreciate that it doesn't require the hardware to be plugged in, so I can go back and analyze captures even from a different computer. It would've been easy to use that as an authentication method, and I'm so glad that it isn't.

No instructions what to do (should I uninstall the old one first?)2. Have a way to restore default setting. I worked on one project, set up the signal names, order, etc. Now I want to start a new one and there is no simple way to undo the setting of the old project so I need to manually undo them. That's tedious.3. Make the device passive when not powered. Currently if I connect the USB port, my circuit does not work due to the device's load.4. Have a LED indicator. It's not obvious when it is actually powered (see #3 above).5. Have better marking of the pins. On my my Logic 8 they are marked on the *bottom* of the case.6. Have consistent packaging. My Logic 8 arrived with a way too big case that was clearly different from the nice one I saw in your marketing material. I had to by an after market one. That's not good.7. Have more flexible wires. They are too hard for such a small and light case (tail wages the dog).8. Same goes to the provided USB cable. Find a more flexible one. I am using a cable removed from a retraceable cablehttp://richardsolo.com/usbretractablecable.aspx#.U0gKw61dV-8For the record, I just completed an automative project and my Logic 8 was extremely useful. Don't know what I would do without it.

content: Neslekkim: We have 4 new products total. And yes, the new Logic 8 has huge buffer space, it should be extremely reliable compared with the original logic. Your question makes me think that we're probably not doing a good job on our site indicating that that “Logic 8” is a brand new product – I’ll see what we can do to fix that.SirNick: Mark and I really loved your post last night, awesome! I also appreciate and agree with your criticisms.Mojo-chan: We originally did set out with the ambition of creating something along the lines of a full blown, awesome MSO, something with at least 100MHz of analog bandwidth. We actually spent a lot of time on it before we figured out it was too big a project for our company at the time. We’ll see how things go but hopefully we can do it in the future.Jpb: Regarding trigger out: I agree this would handy; unfortunately we decided against the feature because it would have greatly complicated how we do the trigger, and it would have added too much time to the project. Mainly because people would want to trigger on protocol – and use that to trigger the scope; that means the trigger would have to be in the FPGA and very low latency, and would require re-writing all the protocol analyzers to run in HDL – not a project we wanted to take on just now. Sorry we couldn't get it in there!Zapta: Great stuff, thank you.The new Logics should no longer load the circuit in any way. Logic16 should not either.The new Logics all have LEDs now.Contact me at support.saleae.com and we’ll send you a new wire-harness. I really like the ones we have now.I’ll see what we can do about the upgrade process, and the markings on the front of the device (that hasn't been finalized yet). And I certainly agree that the case you get needs to match the one in the picture!In the current software (this will be changing) if you hover your mouse over the channel name a little button will appear, and you can select Reset->Everything. That should restore most of the settings for you.

content: Quote from: JoeGarrison on April 11, 2014, 06:26:30 pmI've never seen, let alone used one of your products, but based on comments and recommendations on this forum I have started to seriously consider one (my current logic analyzer is a 30-year old HP 1631 with a 1K sample size!). I haven't even read a Saleae spec sheet, but I had simply assumed that there would be a trigger out, and learning that there isn't one (even for straight-forward combinatorial triggers) is raising a flag in my mind. I understand your argument for why it's not there (at least as far as a protocol trigger goes), but it wouldn't *have* to be a low-latency, low-jitter signal to still be enormously useful. Digital scopes make it easy to acquire whatever pre-trigger data might be required to allow a user to place the logic analyzer's output data stream into context, so that even without a tightly defined latency you will still be in the ballpark.Just my two cents worth...In any case Joe, it's great to see such a visible presence of a manufacturer.

content: Hi Sailor, your comments are well received, thanks. We did look into doing this extensively early on.On the PC side the data path is very pipelined and non-deterministic – lots of threads -- so if we send down a message to the device that a trigger has been found it would probably be 100s of ms of latency and maybe more – far too much for the scope assuming you need any sort of bandwidth. So it would have to be done on the device itself, and ideally in HDL. It’s certainly doable, bit it could be a lot of work depending on exactly how flexible you want to make it. It’s something we’ll have to do if we end up doing an MSO down the road.The Logic Studio from LeCroy is set up to do exactly what you’re looking for, you might take a look:http://teledynelecroy.com/logicstudio/

content: Oh dear. So **everything** is done in the PC? Without belittling it in any way, the hardware is essentially (just) a latch-and-serialize device?There I go, Ass-uming things again.I'm really going to have to start reading datasheets before opening my mouth.Sorry Joe, my bad.

content: Quote from: JoeGarrison on April 12, 2014, 03:06:23 amThe Logic Studio has a similar latency on trigger to the LogicPort (100 to 150nsecs I think). I have a WaveJet scope so I looked at the logicstudio first of all but it is very expensive, it doesn't work with the early WaveJet scopes, just the A series (I exchanged several e-mails with TeledyneLecroy over it - it only works via USB and not via ethernet) and if you read the reviews on Amazon.com there is one which says it is not very good and the LogicPort is a lot better.http://www.amazon.com/LeCroy-LogicStudio-16-Analyzer-Channels/dp/B0094JW9YS/ref=sr_1_1?ie=UTF8&qid=1397297492&sr=8-1&keywords=LeCroy+LogicStudioFor the cost of the logicstudio you could buy a LogicPort to do the triggering and a Logic 16 Pro for the long memory and still have change left over I think.I'm fairly ignorant on logic analysers, so I don't know if connecting two would overload the circuit.

content: Quote from: bench_knob on April 12, 2014, 02:01:33 pmWhat kind of tiny monitor/resolution are you using? 640x480? On my basic run of the mill 14" laptop the traces take up close to 80% of the screen, and the horizontal resolution is nowhere near what you get on a regular 1080p or 1920x1200 monitor, which would have even more trace area.

content: I think the traces being covered with decoders looks like something they are going to have fixed in the newer version that is shown off in video on their website. It looks like there is a small area above the trace now for this purpose if I am understanding properly.

content: Quote from: neslekkim on November 20, 2014, 08:50:41 amThere's a little bit here:https://www.eevblog.com/forum/testgear/saleae-logic-pro-8-quick-teardown/But the problem is there's no released software yet, so it's premature to do a real review. Beta versions are appearing about every 1-2 weeks.I've had my Pro-16 for more than a month and there's still a number of major issues:1) There's no analog calibration data from Saleae yet for my specific device (calibration data is downloaded - weird, huh?), so analog is useless.2) I'm running Linux and Linux USB 3.0 support isn't in the host SW yet, so no high capture rates.3) I can only use USB 2.0, and because of that I can only use 8 of the 16 ports due to power limitations.I went to go buy another Logic (old, 8 port version) and I noticed they've discontinued it and and the old Logic 16. The last released version of host SW is 1.1.15 and it doesn't support any of the new devices. So Saleae, at least currently, isn't selling any released products.Their technical support is still very responsive and I'm confident they'll deliver, but they've got themselves in a pretty big hole right now.

content: Update: Beta 1.1.31 has just been released and it has some important Linux improvements:1) USB 3.0 is now supported, BUT you need kernel 3.3 or better.2) You can now override the USB 2.0 power restrictions and use all 16 channels on a Pro-16 with a USB 2.0 connection. BUT, because the Pro-16 needs more power than USB 2.0 can provide, you need to use a powered hub or some device that will actually provide more than the 2.0 maximum.So, although that's some good progress on the Linux front, I'm unfortunately still stuck. My machine with USB 3.0 has some other software dependencies that has me tied to kernel 3.2.58. That's going to take me a while to get upgraded to a newer Linux distro.The 2.0 option seems to work ok, but because it appears to be implemented by making the Pro-16 lie about its power requirements in the initial USB enumeration, it might be possible to brick it if you don't have a USB 3.0 host or a USB 2.0 device capable of supplying the power. Beware if you turn this on.And my unit's calibration data is still not available, so I'm still stuck without analog anyway.So FYI, if anyone else with Linux and a Pro-8/16 wants to give it a shot. It looks like it could work now with the right kernel.
