Description: The Digilent Analog Discovery 2 is a USB oscilloscope and multi-function instrument that allows users to measure, visualize, generate, record, and control mixed-signal circuits of all kinds. Developed in conjunction with Analog Devices and supported by Xilinx University Program, Analog Discovery 2 is small enough to fit in your pocket, but powerful enough to replace a stack of lab equipment, providing engineering students, hobbyists, and electronics enthusiasts the freedom to work with analog and digital circuits in virtually any environment, in or out of the lab.

The analog and digital inputs and outputs can be connected to a circuit using simple wire probes to connect and utilize the inputs and outputs. Driven by the free WaveForms 2015 (Mac, Linux and Windows Compatible) software, Analog Discovery 2 can be configured to work as any one of several traditional instruments.

Includes:

  • Analog Discovery 2
  • Enclosure
  • USB A to micro B programming cable
  • 2x15 flywire signal cable assembly
  • 5-pack of 6-pin male headers
  • Ferrite cable snap-on

Features:

  • Two-channel USB digital oscilloscope (1MΩ, ±25V, differential, 14-bit, 100Msample/sec, 30MHz+ bandwidth - with the * Analog Discovery BNC Adapter Board)
  • Two-channel arbitrary function generator (±5V, 14-bit, 100Msample/sec, 20MHz+ bandwidth - with the Analog Discovery BNC Adapter Board)
  • Stereo audio amplifier to drive external headphones or speakers with replicated AWG signals
  • 16-channel digital logic analyzer (3.3V CMOS, 100Msample/sec)
  • 16-channel pattern generator (3.3V CMOS, 100Msample/sec)
  • 16-channel virtual digital I/O including buttons, switches, and LEDs – perfect for logic training applications
  • Two input/output digital trigger signals for linking multiple instruments (3.3V CMOS)
  • Single channel voltmeter (AC, DC, ±25V)
  • Network analyzer – Bode, Nyquist, Nichols transfer diagrams of a circuit. Range: 1Hz to 10MHz
  • Spectrum Analyzer – power spectrum and spectral measurements (noise floor, SFDR, SNR, THD, etc.)
  • Digital Bus Analyzers (SPI, I²C, UART, Parallel)
  • Two programmable power supplies (0…+5V , 0…-5V). The maximum available output current and power depend on the Analog Discovery 2 powering choice:
    • 250mW max for each supply or 500mW total when powered through USB
    • 700mA max or 2.1W max for each supply when using an external wall power supply

  • Just an FYI this product is $179 from Digilent once you register an account and verify it with your school email. I’m a student so every penny counts!

    • I’m not a student, I just pay for their educations. Not only am I paying directly through tuition payments, but there’s also my property taxes which pay for K-12 for everyone in my county as well as my state and federal taxes which pay for universities throughout this nation.

      I’m not still living off my parents with subsidized health care and since I’m over 18 I’m actually responsible for my debts. So every penny counts for me, too, but Digilent will only sell to me at the same price as Sparkfun. Enjoy it while you can, kid. The Real World’s gonna get you soon!

  • Mine should arrive today. Looking forward to it.

  • The logic analyzer is listed under the 3.3V peripheral section; are the inputs 5V tolerant?

    • Section 5. of the datasheet page “Input and output pins are LVCMOS3V3. Inputs are 5V tolerant. Overvoltage up to ±20V is supported.”

  • Has anyone had luck installing waveform 2015 on a raspberry pi? I put it on my Linux PC with no problem. But the install fails on the pi.

    • Has anyone had luck with this and a raspberry pi? I’m getting communication errors even with an external power supply.

    • OK I worked through it: first download these files: digilent.adept.runtime_2.16.1-armhf.deb digilent.waveforms_3.4.7_armhf.deb digilent.adept.utilities_2.2.1-armhf.deb

      the files are found on the websites: https://reference.digilentinc.com/reference/software/waveforms/waveforms-3/start https://reference.digilentinc.com/reference/software/adept/start

      then run the commands in this order:

      sudo dpkg -i digilent.adept.runtime_2.16.1-armhf.deb

      sudo dpkg -i digilent.adept.utilities_2.2.1-armhf.deb

      sudo dpkg -i digilent.waveforms_3.4.7_armhf.deb

      then plug in the Analog discovery with waveforms running. Now I’m having trouble with the power requirements

      • Post the problems you are having on the Digilent forums. I hear the developer is on the scopes and instruments section so you’ll get the best help there.

  • hi can this be used as sound card? to send out digital audio signals from my computer via USB and turns into -5V~+5V signals?

    • I’m not really sure. It looks like you could upload small .wav files to play it through the wavegen on the software, but it doesn’t seem that you can send a stream of data from your computer. Perhaps that’s something that can be done with the scripting?

  • Please confirm: do I need power supply to operate? What do you offer?

    • You only need a USB cable (included) to use the device. If you want to drive more current from the digital output pins (up to 700mA total), then you’ll need a wall supply like this one.

  • I was excited to see this until 1) saw the price and 2) Windows ONLY software? Yea, No.

    • Actually the software is Mac and Linux compatible (waveforms 2015). http://store.digilentinc.com/waveforms-2015-download-only/

  • Cool unit. WAY overpriced.

  • Would this be suitable for HF Amateur radio applications?

    • It’ll work, but you’ll be pushing the device at the upper end of your HF spectrum (30 MHz). Keep in mind that the scope will see a -3 dB attenuation at 30 MHz, so your readings will be a bit off. To even work in the 10MHz - 30MHz range, you’ll need Digilent’s BNC adapter and real scope probes. The included wire harness won’t really work above 9 MHz.

  • Looks awesome! I look forward to having my own one day.

  • Is the Labview Home bundle version of Labview compatible with the Analog Discovery 2?

    • There looks to be a LabVIEW tool kit. http://sine.ni.com/nips/cds/view/p/lang/en/nid/213660

  • Seriously guys? You don’t even carry the BNC breakout board, and you’ve added $100 to the price?! What the hell?

    • It’s not really fair to compare a student-only price to this. You have to go through a pretty in depth academic verification to get that price + sign off that you are willing to be contacted regularly by Digilent. 279 is a pretty good price for the features/specs and in comparison to what else is out there.

    • We’ll definitely look into it. Right now we’re seeing if this will sell, if it sells well we’ll look into add-ons.

    • It’s almost $400CDN… that’s just mental considering it’s $179USD on Digilent’s website.

  • The feature list is nice but a $3 MCU can do most of it. If it was an open source project the cost would be 1/10 …

    • Part of what you’re paying for is the software that makes the hardware run. A lot of work goes into making the software easy to use and feature rich.

    • Nope. An MCU doesn’t include dual 100 MHz DACs and ADCs. Those parts aren’t cheap.

      Perhaps the most directly comparable competitor is Red Pitaya. But it doesn’t have the overvoltage-tolerant I/O pins that this does - it would need an accessory board to make it suitable for use as a general purpose logic analyzer.

    • I hope you are only trolling or didn’t read the specs.

      Analog Discoveries (both the old one and this one) are fairly serious all-in-one lab instruments. Here you are getting a mixed signal oscilloscope and arbitrary signal generator + logic analyzer. This thing runs circles around most of the USB “oscilloscopes” on the market.

      Good luck trying to achieve any of that with a $3 micro.

      Red Pitaya is perhaps a bit more powerful in terms of the raw hw, but the Analog Discovery has much better software and support. If you want an instrument instead of a dev board, the Discovery is a lot better deal.

      However, Sparkfun should carry also the BNC breakout board that goes with it, so that standard scope probes and coax cables for the generator can be used. http://store.digilentinc.com/bnc-adapter-board-for-the-analog-discovery/

    • False. A $3 MCU will not do most of the things on this feature list. You could do a few of the things on the list, but not most of them. Why would it being open source make it magically cheaper? Fast, precision measurements cost money. If it’s so easy and cheap, where’s your replacement?

Nice, but a steep learning curve

This appears to be a fairly new product for Diligent, improving upon the Analog Discovery. Getting it up and running was a challenge. It pulls too much startup power for most USB ports, and therefore I had to buy an externally-powered USB hub. The documentation on it is still evolving, although the Diligent forum was very helpful.
All that said, I really like the unit, and it does just what it is supposed to do. So I do recommend it.

I like it a lot!

I actually haven’t had a chance to use it much. But I did use it to verify the output of a serial port for a python driver I was working on for a half-cube oven. I allowed me to confirm what was coming out of the port in response to my software commands. This meant that when I actually tried my code out on the oven itself, the code worked first time.

Mighty useful

I see a lot of oscilloscopes every day at work in the semiconductor industry. This is really a good solution for home or on the road when you need to capture a couple of plots. This would even cover 80% of what I typically capture at work.

Two channels only you say? Sure, channels are like free beer; we could always use more. But don’t stick up your nose at this little beauty, learn to capture only what you really need.

All the software configuration is easy and the fact that it runs on my Mac is huge benefit.

Great Little Tool

I really like the software. It just works. Not the fastest scope or logic analyzer but good enough for most jobs. I have recommended it to several others.

Versatile,small and easy

Wow, very impressed. Portable, reasonable SW and includes SW for a spectrum analyzer, oscilloscope, etc etc. Can re-calibrate anytime which is re-assuring.

I have a Saleae Pro 16 channel and its really cool but this is great addition. Not as solid as the Saleae in a plastic case but the price makes up for this weakness.

The js programming capability is a real plus too.

Good gear

This guy works much better than my bitscope. Don’t get me wrong, my dual channel bitscope has got me through some binds, but every once in a while it acts glitchy. Sw crashes etc. It gets frustrating. I haven’t been seeing any of that sort of thing with the diligent gear. Pricy but worth it.

Love it

Very versatile. Software is easy to get and install, had it up and running in literally minutes.


Works Great, small driver issue...

Awesome product, just one small problem running WaveForm software the very first time on macOS. Had a heck of a time detecting the hardware and had to dig through forums looking for a way to get it hooked up. After that though it has worked flawlessly.
