Latest Prototype is In

Latest prototype is in, and it works great! (Well, there’s always some issue - hence the little wires hacked on near the BNC inputs in the picture!)

One new feature is switchable “super high gain mode”, for when your signals are smaller than +-300 mV. There’s some limitations, such as 10k input impedance, and bandwidth is reduced to ~2 MHz in this mode (gain bandwidth product is a killer!). But now you can see signals down to +-3 mV full scale. That’s 20 uV per bit!

Here's a 1 mV 100 kHz square wave. Not bad!

Product Choices


Your very own Haasoscope!

A fully assembled Haasoscope, preloaded with firmware and ready for data-taking! You also might want to grab a USB-serial adapter (for interfacing to a computer) and/or a USB-blaster (for reprogramming the firmware).



This lets you reprogram the Haasoscope FPGA firmware from either Windows or Linux using the free Altera Quartus II software via the JTAG connector.


A Cool Screen!

This is a 0.96" 128X64 pixel white OLED screen. It communicates with the Haasoscope over an SPI interface, and can show ADC data from a selected channel, or whatever you tell it to! It can plug directly into the header above the FPGA.


Oscilloscope Probes

Two passive 100 MHz bandwidth oscilloscope probes for connecting to Haasoscope 100 MHz ADC inputs using BNC.


High-speed USB Readout Board

In case 1.5 Mb/s is not enough bandwidth for you, grab one of these boards and have high-speed USB2 output from a Haasoscope! Using just 8+2 digital outputs on the Haasoscope, you can get about 4 MB/s, about 20x faster than serial, and still use the same python readout code. It's supported in the stock firmware too! Using 8+4 digital outputs, you could in theory even get up to 40 MB/s using C++ readout code and the free FTDI USB libraries.
