The Hantek 6022BL is a USB-based, 2-channel oscilloscope with an analog bandwidth of 20MS/s and 48MS/s sampling rate, and an 8-/16-channel logic analyzer with 24MHz sampling rate.
The device can either be used as oscilloscope or as logic analyzer, but not both at the same time. I.e., it is not a mixed-signal-oscilloscope (MSO).
Currently only the 8-channel logic analyzer mode is supported.
See Hantek 6022BL/Info for more details (such as lsusb -v output) about the device.
Hardware
- USB: Cypress CY7C68013A-100AXC (FX2LP) (datasheet)
- 256-byte I²C EEPROM: 2x Microchip 24LC02BI (datasheet)
- 16-Bit bus transceiver with 3-state outputs: TI SN74LVC16245A (datasheet)
- 8-channel analog mux/demux: 2x NXP 74HC4051D (datasheet)
- 1A low-dropout voltage regulator (3.3V): Advanced Monolithic Systems AMS1117-3.3 datasheet)
- 2W, fixed input, isolated & unregulated dual/single output DC/DC converter: Mornsun A_S-2WR2 (A0505S-2WR2) (datasheet)
- ADC: (educated guess, IC covered by glued-on heatsink)
- 8-bit, 40/80/100MHz, dual ADC: Analog Devices AD9288 (datasheet), or
- 8-bit, 100MHz, dual ADC: MXTronix MXT2088 (datasheet)
- 1.4GHz current feedback amplifiers with enable: 2x Intersil EL5166 (datasheet)
- 145 MHz FastFET Opamps: 2x AD8065: (datasheet), markings "HRA"

- Attenuator: Hantek HT-201 20:1 attenuator (10MHz bandwidth, 1.053M input resistance)
The device has a "H/P" button. Depending on whether or not it's pressed it comes up with different USB VID/PIDs:
- Pressed: 04b4:602a Cypress Semiconductor Corp. (used for oscilloscope mode)
- Not pressed: 0925:3881 Lakeview Research Saleae Logic (Saleae Logic VID/PID, so fx2lafw works out of the box)

Protocol
When the "H/P" button is not pressed, the device can be used as 8-channel 24MHz logic analyzer via fx2lafw out of the box (using the fx2lafw protocol).
