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-channel logic analyzer with 24MHz sampling rate.
See Hantek_6022BL/Info for more details (such as lsusb -v output) about the device.
Note: Currently only the logic analyzer part is supported, the oscilloscope part is work in progress.
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: 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: ?
- ?: S1661SZ B212FG
- Crystal: 24MHz
- Probes: 2x PP80B 1X/10X 80MHz bandwidth oscilloscope probes
- 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)
Discovered connections:
- The Pins 1DIR(1), 2DIR(24), 2OE(25) and 1OE(48) of the Bus transceiver (U4) are all connected to pin PA7(74) of the CY7(U2).
- Pin PA7(74) of the CY7(U2) is also connected with R37, which is the base resistor for Q2.
- Q2 is connected to Q1 over R13.
- Q1 is connected to pin S1(8) of the ADC(U8).
- Pin S2(9) of the ADC(U8) is connected to GND.

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).
