"There’s been a fair amount of talk about this over at the EEVBlog forums, essentially comparing the bandwidth to dollar ratio. I reckon it’s a pretty decent DSO for the price."


"Esta placa de adquisición de datos y osciloscopio realizada de forma abierta es capaz de permitir la realización de sistemas altamente complejos"

Haasoscope is the first open source, open hardware, flexible, small, cheap, oscilloscope and data-acquisition board. You can use the stock firmware for basic oscilloscope functionality, or modify the firmware to customize what the Haasoscope does. You can add a fancy trigger algorithm, use the FPGA to process the input data, make use of other analog or digital I/O channels, or whatever! Oh, and just connect two or more Haasoscopes together if you need more input channels!

Haasoscope is also far more powerful than a normal oscilloscope. Imagine trying to build a ping-pong playing robot, a levitating magnetic platform, or a self-navigating drone - you’d need to read in high-speed data from various sensors, analog and digital, process all that data quickly, and respond in real-time. No problem - Haasoscope can handle that, even while running on batteries.

Who Needs It and Why?

If you’re a hobbyist on a budget, there’s no need to buy a $500 scope to debug circuits anymore, even high-speed ones. Haasoscope has all the features you need, plus it’s expandable and customizable, can be powered from USB, and fits in your pocket - all at a fraction of the cost of a full size ‘scope.

Haasoscope is also a great platform for students. They can see high-speed circuits in action, learn FPGA programming, data transmission protocols, etc. - at a price affordable for the classroom. They’re perfect for a lab class in EE, CS, or physics.

You can even use Haasoscope for professional work - scientific research, industrial applications, communications, security, entertainment, finance, … anytime you need to tackle high-speed data on a project. Haasoscope’s flexibility and expandability lets you build a system that meets your needs, whether it’s four channels and solar-powered in a remote desert, or 400 channels monitoring electronic noise levels in a cell-phone tower.

Features & Specifications

  • Four high-speed ADC channels, up to 125 MSPS each, 8-bit, ~60 MHz bandwidth, BNC inputs
  • Switchable oversampling to make two very high speed ADC channels, up to 250 MSPS each
  • Intel/Altera MAX10 FPGA with 8k logic elements and 387 kb of memory (enough for 8k samples / channel for each event)
  • Reprogram firmware over JTAG with free Altera software for Windows or Linux (or VirtualBox on Mac)
  • Python user software for waveform display and control of all features, including FFT
  • Four gains per channel: +-4 V, +-400 mV, +-40 mV, and +-4 mV ranges, with programmable DC offset
  • Switchable AC/DC input, 50/1M Ohm termination for each channel
  • Readout over USB-serial at 1.5 Mb/s, about 20 Hz for four channels of 512 samples each, works with PCs, Raspberry Pi, Arduino, etc.
  • Optional USB2 hat for 20x faster readout
  • Optional 128 x 64 mini display with SPI interface
  • 22 spare high-speed digital I/O (100+ MHz)
  • 4 spare low-speed digital I/O (via I2C bus)
  • 9 additional analog I/O, 1 MSPS (combined) at 12 bits
  • 4 programmable LEDs and a reset button
  • USB powered, (or other 5 V input, switchable), ~1 Watt
  • 6.2 x 8.9 cm (just bigger than a credit card)
