Scopy crashed couple of times though. I need to find some repro steps and report the bugs.
Still need to test the logic analyzer but overall i'm really satisfied.
Tried to check bandwidth my ADALM2000 with HP8648B SSG.
This result is acceptable for me to use my application environment.

Cool, so the BNC adapter board from Digilent is working. I ordered one and should receive it this week.

Did you terminate the coaxial-cable with 50 ohms?
I do not use any terminator, connect 50 ohm coaxial cable directly.
HP8648B output impedance is 50 ohm. I guess the ADALM2000 input impedance is 1M ohm? (Higher than 50 ohm)

Without a 50ohm termination, your test has limited value and applicability in other circumstances.
A scope's input impedance is only 1Mohm at low frequencies. Hint: what's the impedance of the parallel 30pF capacitor a 1kHz, 1MHz and 10MHz?

Today my Scopy crashed several times too. I found the reason: The USB-cable. I exchanged it and no crashes anymore when moving the cable.

Yesterday I measured the required current for the ADALM2000, rev. C. Only USB, no external power supply connected.
Software: SCOPY, no external devices connected.
Standby (not "Connected") 0,23A
"Connected" 0,41A
Signal-Generator 0,55A +- 0,02A
Network-Analyser 0,53A
all other modes 0,43A +- 0,02A
If you use the ADALM2000 only for measuring, no external power supply seems to be necessary.

I ordered mine from Mouser in November 2017 and it arrived today November 2018. I opened the box and it only contained the ADALM2000 a USB cable a few pins and no pigtail breakout connector

In fact there should be two: 2x5 and 2x10.
Thanks, MrW0lf for letting me know that there should be 2 connectors. I have emailed Mouser and am awaiting a reply. The problem I can now see is on the Mouser website they have no stock and 27 weeks lead time. Update Nov 21 Mouser were to look into the issue and were to get back to me 1 week later nothing is happening.

Huh? A 2x5 and 2x10? What is on the other end of those cables?
Nothing special just 1 pin female header.
BTW the Digilent BNC adaptor is working fine with the ADALM2000. It's useful to connect a standard oscilloscope probe.
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.

Huh. Weird. I only got that big breakout you see in the photos here, an extra tall pin header strip and a USB cable.

I've not used a WiFi adapter but I did try it with a USB Ethernet dongle and it worked fine.
It took a lot of chasing AD but I've finally got the missing case.
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.

Did you install the ADALM2000 version of ALICE + libiio? The ADALM1000 version isn't compatible.

Yes, the version is "alice-2.0-m2k" containing the iio.py source file. 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.
Ah. I've no experience of the Linux version. The Windows version does run but its very clunky and buggy in places.
There may be something wrong with the libiio build, or the installed version 0.15 is not compatible with the Alice 2.0. Oh well ...
Solution to Alice 2.0 not finding Adalm-2000 on Ubuntu 18.3: one needs to build the libiio with USB support. Please see this page for further information:
https://wiki.analog.com/resources/tools-software/linux-software/libiioFor some reason I didn't have the libiio built with USB support when installing Adalm-Pluto, thus Alice could not connect to Adalm-2000.

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 ?
I also like the network analyzer. Pretty useful.
The X-Y mode is also decent (Better than my full-fledged oscilloscope anyway). Was improvising a component tester with a transfo and a resistor.
