The Xprotolab is the first mixed signal oscilloscope with an arbitrary waveform generator in a DIP module. It measures only 1 x 1.6 inches, and can be mounted directly on a breadboard. The Xprotolab can also be used as a development board for the AVR XMEGA microcontroller.


  • Mixed Signal Oscilloscope: Simultaneous sampling of analog and digital signals.
  • Advanced Trigger: Normal / Single / Auto, with rising or falling edge and adjustable trigger level.
  • Meter Mode: Average, Peak to peak and Frequency readout.
  • XY Mode:
    - Plot Lissajous patterns
    - See the phase difference between two waveforms
    - V/I Curve tracer with an external resistor
  • Spectrum Analyzer with different windowing options and selectable vertical log.
  • Horizontal and Vertical Cursors with automatic waveform measurements.
  • Arbitrary Waveform Generator with Sweep on all parameters.
  • Display options: Persistence, Different grid options, and more.

General Specifications:

  • Graphic OLED display 0.96", 128x64 pixels
  • Module size: 1.615" x 1.01"
  • PDI interface.
  • 4 tactile switches
  • USB connectivity: Windows, Linux, MAC, Android

Logic Analyzer specifications:

  • 8 Digital Inputs, 3.3V level
  • Maximum sampling rate: 2MSPS
  • Frequency counter: 16Mhz
  • Protocol Sniffer: UART, I2C, SPI

Fantastic! I built this up to use in my Eurorack system, and it works great!

I received the Xprotolab today and had it up and running in 10 minutes. I am very impressed. It is exactly what I need. The FFT is just amazing. I had been searching for this for a long time. The menu with just four buttons is easy and well designed. Just ordered an Xminilab for integration into an HF transceiver and an Xminilab portable for the shack.

I have to admit, this device worth every penny!There are several "pcb like" oscilloscopes on the market, however I choose this because it have an x-y input.Screen is small but I can read it easily. I am almost 50 years old, I haven't my twenty's vision, however I'm not wearing yet eyeglasses either. In my condition I can read every character on screen.The most impressive is the huge number of functions in this tiny device!I place my own DIY pcb behind it, to turn it into a powerful fully parametrical component tester (Tracer). Since then I make amazing measurements which I couldn't done them before, and all in an absolutely portable way.For power supply I use a micro-usb phone charger or a $5 powerbank, which last for days or even weeks!Thanks again!Wish list:Hide usb and serial connector behind screen, to make device even smaller, at the same screen size.May add a backwards menu button.Faster Auto trigger if possiblePlotless trace at XY mode.

I have both XProtoLab's, with screen and without. The one with the screen works very well when you can see it. You need a very good magnifier. The other you have to use the interface. I am running windows. The interface has so many problems I am just not sure where to begin. They have not updated it since I bought mine. Everything on the site is last YEAR.
The screen crashes but the board is still working. It is so unstable that its unusable. I would like to see some updates and if you have new firmware for the boards I would to get it.

This product is worth every cent! The display is beautiful and the features are rich. It is perfect for audio applications. You will have a lot of fun with this little device. Guaranteed.

However, there are two problems I'd like to point out:

Problem 1:
It is IMPOSSIBLE to install the drivers on Windows 8. Microsoft doesn't allow you to install this driver unless you have a valid certificate (which one has to buy for sixty dollars). This is not necessarily a problem of the device itself, but rather a problem created by Microsoft.

Problem 2:
When one uses the waveform generator, the amplitude changes when generating signals over 10kHz. This problem should be fixable to an extent by code though... :/

I want to say that I really like what I have seen so far, WRT the hardware design. (XMultiKit)
