Hantek 6022BE

The Hantek 6022BE is a USB-based, 2-channel oscilloscope with an analog bandwidth of 20MS/s and 48MS/s sampling rate.

See Hantek_6022BE/Info for more details (such as lsusb -v output) about the device.

Firmware

We use the open-source firmware file hantek-6022be.fw from sigrok-firmware-fx2lafw for this device. The firmware was originally written by Jochen Hoenicke (see README for details), thanks a lot!

The protocol of the open-source firmware we use (see below) is similar, but not identical, to the vendor's firmware protocol. The vendor firmware was originally reverse engineered and documented for the Hantek6022API project. The open-source implementation was done from scratch, though.

Note: The firmware is not flashed into the device permanently! You need to only make it available in the usual place where libsigrok looks for firmware files, it will be used automatically (and "uploaded" to the Cypress FX2's SRAM every time you attach the 6022BE to a USB port).
