content: I am considering purchasing an ADALM2000 from Analog Devices. I want to pair it with an inexpensive windows tablet for a general test equipment set up good from DC to 10 MHz.Link to the kit is:http://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/adalm2000.html#eb-overview.It uses the AD "Scopy" software. The link for the wiki for the software is:https://wiki.analog.com/university/tools/m2k/scopy.Any thoughts or recommendations appreciated, especially with respect to the AD hardware and software.VR,Kevin

content: I guess this might have been developed by/in collaboration with the guys at Nonolith labs (acquired by AD) who designed the CEE and later the ADALM1000. Sorry, no experience or other information. Looks like this is aimed more at the measuring and less at the sourcing/sinking. But it adds a much faster sampling rate and digital I/O.It is cool that they open-sourced their software.

content: I bought an ADLM1000 on the promise of lots of tutorials and software.Alas, no version 1.0 of the software ever appeared (nor the tutorials as far as I know).It seems that Analog Devices made the hardware, and some hobbyists / guys in a garage (Nonolith?) were responsible for the unfinished software.I'm afraid this was a typical case of beware of buying vaporware.To be honest, I was rather shocked that a reputable company like Analog Devices would release an unfinished product like this - and not finish it. Surely we should expect a big company to develop a product first, then sell it?So, I'm very wary ofanythingthey produce now other than their chips - in fact even of their chips.Of course, the ADALM2000 may be different - but the ADALM1000 has certainly been a disappointment.

content: Sooner or latersomeUSB-style scope platform will explode due to open-source  software. Question is will this? I'm browsing thru documentation right now and all very raw. Some dates hint that it was sort of supposed to go on sale in may but seems actually only now!?Software seems to have mostly same stuff that AD2 has but much less fine grained features and more touch-oriented.AD2 has scripting (instead of open-source) but this has not "exploded" possibly due to quite crap documentation and no big easy-to-find library of ready made stuff.So... So far no-one has ticked all the boxes to go nuclear.

content: I think the ADALM2000 is a Zync-based partner of the ADALM-PLUTO SDR unit. Both very new, powerful and low priced, but in short supply at the moment.Concerning tutorials for both ADALM1000 and ADALM2000, they are athttps://wiki.analog.com/university/courses/alm1k/alm-labs-listandhttps://wiki.analog.com/university/courses/electronics/labs. Also, useful info and links to the latest software on the Wiki pageshttps://wiki.analog.com/university/tools/m1kandhttps://wiki.analog.com/university/tools/m2k.Note that these devices are designed for students (and others) to learn electronics. They're very good for that (and excellent value for money) but are not intended tobe used as a substitute for benchtop test equipment.

content: I daresay PixelPulse could be improved, but it works OK, as does the Python-based Alice software. I haven't used either of them very much. More recently, I installed the MATLAB support package for the ADALM1000, as MATLAB is a good way to acquire and analyse data. The pic below* shows the I-V characteristic of a LED (based on an example). These are basically point-by-point DC measurements, averaged 1000x to reduce noise.The 'SMU' capability of the ADALM1000 is quite impressive for such a low-cost device, and it opens up a lot of possibilities for looking at diodes, transistors, etc, as described in the ADI lab tutorials. I can't fault it for value for money, particularly for electronics learners who don't want to spend a lot of money to get started. I would not regard it as 'test equipment', but it's a great learning tool.*Sorry, can't upload a file at the moment - connection keeps resetting

content: The ALICE software claims it works with MacOS X - but there are no instructions for how to compile or run it. Trying to build the needed libsmu on my Mac following the github instructions just results in build failure. I've pointed this out to the chap who looks after the ALICE pages, so perhaps things will improve.

content: Not sure if this will help you, as I'm using a Windows PC.It's a while ago, but I think I installed libsmu first using a file called libsmu-setup.exe. For Alice 1.0, I then unzipped alice-1.0.zip into a folder - it's just a collection of Python files. So, I suppose the key thing on a Mac is to install libsmu (somehow), and the rest should be easy.

content: On my Windows PC, it looks like the installer created a folder C:\Python27\DLLs which contains a single binary file, libpysmu.pyd.Can you put your compiled libsmu into an equivalent place on your Mac? It may help to google something like 'Mac Python library' to find the required location. Various suggestions here:https://stackoverflow.com/questions/2741496/location-of-global-libraries-for-python-on-mac.

content: Running Alice is quite easy on a Mac. All you need to do is compile libsmu (including python module) and install it any where on your Mac (even to the Applications directory in your home directory). To compile you will need the developer files for libusb 1.0 which you can get from Macports or Homebrew. Once you have libsmu library and python module installed, you need to ensure they are in your python path and dynamic library load path. You can do this, if necessary, by setting the environment variables PYTHONPATH and DYLD_LIBRARY_PATH. Now you can just use the hash bang mechanism to run Alice (single python file) software from anywhere.

content: I agree AD2 is relatively expensive when compare to conventional Chinese scope. However if investigate it as "swiss knife" type device possibilities as rapid prototyping helper are quite overwhelming. So cannot judge it as simply MSO + signal gen, must take account all extra I/O that could (be programmed to) do quite complex stuff. Since there are little to no devices with such toolset it is not immediately obvious how to use it to full potential. So many times I have defaulted to Arduino (Due) for this type of activity because for almost every task can instantly find example somewhere. Not the case with AD2. Similar with STM32 vs Arduino. Technically STM32 wins but one has to be quite good with MCUs or have lots of time at hand.Anyway, when and if ADALM2000 finally arrives - comparing it to AD2 will be good opportunity to take closer look at advanced usage scenarios vs common MSO + signal gen.

I also considered Red Pitaya, but initial version of software was crap (according to eevblog's review). And it costs even more, like 600euro for all features enabled.May be one day I buy one of these devices, 14bit ADC sounds very attractive.Quote from: MrW0lf on October 21, 2017, 04:02:10 pmI agree. With STM32 I had a lot of pain (although mostly because I'm on Linux).So, looking forward to your review.

I updated my PATH so my homebrew python would be found first as well, and set PYTHONPATH, but I'm not convinced I needed to do that.

content: My ADALM2000 has appeared without warning so here is a mini review/first impressions.My unit doesn't have a case despite the photos. The PCB is shoved into a huge piece of clear heatshrink tubing and then the label is taped to it. Looks cheap and tacky.They've had problems iwth getting the cases. If you want a case then you need to email somebody at Analog Devices. Read the Thanks letter for the email address.The box had the ADALM2000 itself in an antistatic bag, a micro-USB cable, a strip of extra tall 2.54mm pin headers, a sheet saying thanks for buying a ADALM2000 and a breakout cable for the pins.It is a rev C board which is the latest according to the github repo. It came with 0.19 alpha firmware.0.20 alphais available.Same upgrade instructions as the ADALM-PLUTO.You'll need theScopy appto make this work. Reboot when it tells you or it doesn't connect. Scopy is a bit sparse looking compared to the Digilent WaveForms app.I've not peeled off the label/heatshrink to confirm but the FPGA/CPU looks to be the same Xilinx Zynq Z7010 as the ADALM-PLUTO. It is running in single core mode again and you can turn on the other core if you want. AD said they had only licensed one of the cores in aforum postfor the ADALM-PLUTO but the end user can enable it. The main ADC/DAC is aAD9963according to Scopy.Same as the ADALM-PLUTO, you can plug in a supported USB WiFi or Ethernet dongle and remotely connect to it over the network which is quite a nice feature.The pinout is exactly the same as the Analog Discovery 2 so the BNC adapter should work on it.Will have to see how much work AD put into the Scopy app and the firmware. The Analog Discovery 2 is 2x the price with a 14-bit ADC/DAC instead of 12-bit and there are far more tutorials for the Waveforms software. What you get for the price is good but the software is a bit lacking since new + alpha release. I've played about with it for an hour or so now and its okay. I've already made it crash a few times.The ADALM2000 could do some interesting things in the future though because of the dual core Zynq Z7010. No clue if other ADALM2000 units will come with a case and what availability will be like however.

content: The 2x5 and 2x10 are keyed. The 2x5 lines up with the oscilloscope differential inputs, grounds, power supplies, and waveform generator outputs. The 2x10 lines up with digital grounds and digital I/O.Has anyone been able to connect Scopy to the ADALM2000 via wifi? I bought one of the AD recommended WIFI dongles, an OTG USB adapter, and edited the config file but no joy.

content: Just received my Adalm-2000 from Digikey. Placed an order last week, and Digikey showed backorder time for a few days then. Now they seem to have some units in the stock:https://www.digikey.com/products/en?keywords=adalm2000Firmware upgrade was effortless. I already had the Analog Pluto SDR installed to my Ubuntu 18.3, so installing Scopy was pretty straightforward,Running Alice has some quirks as the application doesn't seem to find the M2k device. I would very much like to test the impedance analyzer functionality, so I need to figure out how to get Alice up and running.I bought also Digilent Impedance Analyzer module and Digilent BNC Adapter module. Not 100% sure whether the Impedance Analyzer module is supported by Alice, though.

The application starts successfully, but pressing the red "Recon" button followed by Run pops up a message box saying no device plugged in. I also tried run the application with sudo, but it didn't help. Also added udev rules and restarted udev service, but still the same problem.

content: Hi guys,little old topick but still relevant.I got my Adalm a few weeks ago. I tried some network measurements (bode plot) and it is working like a charm. Oscilloscope is not relevant for me. I want only logic analyser and bode plote and spectrum analyser.A perfect toy for hobby, you can actually works and not only guess what is happening with some filters. Next project - extension board for analog inputs/outputs and high speed buffers for digital logic analyser.it has some limitation, but for the price ?

content: Hi guys,board presented by friend of mine mrjoda was my idea and he drawn the first version of PCB.Why? I don't like original Digilent board because if you attach standard bnc scope probes it's huge and often fell down.My idea was something light with inputs at front. And hey! There are probes for those crappy small Chinese scopesI was surprised by quality and decision was easy.And here is result (little bit different from mrjoda drawn)There is additional button for monitoring output of first generator output by ch.1 of oscilloscope. (together with 6db attu is bode plot really simple )There is missing one ninigi connector for PSU which I forgot to order.Next step is design nice 3D printed case.I'm so happy with the result, that's exactly I expected.

content: Discovered something interesting today. I always assumed that the output of the signal generator was calibrated for 50\$\Omega\$ load. Looking at the schematic kind of confirm that assumption.Testing with a multimeter I was observing the right voltage. Ex setting 1V pp I was reading around 0.354V RMS. But a multimeter normally 1M\$\Omega\$ not 50\$\Omega\$. So I did some more testing with my oscilloscope and it look like the default calibration (nothing connected on the signal generator port) is for 1M\$\Omega\$ load.Now the interesting part is that if you have a 50\$\Omega\$ load (terminator or other) connected to the signal generator port during calibration, the signal generator will now be calibrated for a 50\$\Omega\$ load.

content: I'm considering buying a ADALM2000 myself. It has an analog-to-digital sample rate of 100MSPS, which is really impressive, as it means I should get a full 50MHz bandwidth, great for capturing a few seconds of 50MHz wide RF spectrum for later analysis (100MSPS with 12bit bitdepth padded to 2 bytes per sample gives you 200MBytes per second, so a huge file but useful for analysis). Just like a professional high speed digitizer except only a fraction of the price. However the specs sheet athttps://media.digikey.com/pdf/Data%20Sheets/Analog%20Devices%20PDFs/ADALM2000_Web.pdfis telling me I only get 5MHz bandwidth out of it. Apparantly they decided to incorporate an internal 5MHz LPF in it between the input pins and the ADC. A different spec sheet for the same device at a different websitehttps://docs.rs-online.com/fb1d/0900766b815d846d.pdfsays the bandwidth is 25MHz (better than 5MHz for sure, but not as good as 50MHz). What's the actual specs? Did the specs actually change? Did Analog Devices actually modify the manufacturing process for the ADALM2000, so there actually exist 2 different variants of the ADALM2000 (each with different specs), but with the exact same product name?Also, is it possible to bypass the internal LPF (maybe soldering a wire across a component), to get the full 50MHz bandwidth that's possible with a 100MSPS sample rate?

content: Quote from: Kosmic on February 02, 2021, 02:57:28 pmThanks. That would be great if you could check that. Also, does the device's analog input support continuous streaming (sends all samples to the PC)? Or does it only support block transfer (sends a block of samples and then there may be some delay before the next block is sent)? I know that the official Scopy software has an osciloscope mode, that only supports block transfer mode (each block is sent in response to a trigger, or free run, but no guarenty that there will be no delay between blocks). However, I also know that the ADALM2000 has an SDK for you to design your own software, so if the hardware permits a continuous streaming mode for analog input, then I should be able to write my own software to use that streaming mode.

I initially wanted to use the max hold feature but it stop working after some timeMy source was a calibrated IFR2025 with a accuracy of +-0.8dBm.the Spectrum Analyzer app was sweeping from 1Hz to 50MHz with a 762.94Hz resolution bandwidth, gain mode low, averaging 16 samples.The -3dB point seem to be at around 20Mhz. At 49MHz its something like -9dB off.

content: Quote from: Kosmic on February 04, 2021, 02:40:26 amIs it better to use libm2k for this? or is it better to use libiio for this? Part of installation of the ADALM2000 in the first place is installation of libiio on my PC. The only problem I have with using libiio right now is knowing what folder it put libiio in when it installed it. I don't see a libiio folder in either Program Files or Program Files (x86). Of course if libm2k is the preferred method for writing software for controlling the ADALM2000, then I will use that instead of libiio.

I would not be surprise if libm2k was using libiio under the hood.Edit: Yes libm2k use libiio.

Also if libm2k doesn't work with Pluto2000, is there another community created lib similar to libm2k, designed to work with Pluto2000?
