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

The device has a "H/P" button. Depending on whether or not it's pressed it comes up with different USB VID/PIDs:

NXP 74HC4051D (upper/lower, CH1/CH2) pinout:

Y4 1-   O -16 VCC
(GND) Y6 2- -15 Y2
(upper EL5166, IN-) Z 3- -14 Y1
(GND) Y7 4- -13 Y0
(GND) Y5 5- -12 Y3
(GND) E# 6- -11 S0 (FX2 PA1)
VEE 7- -10 S1 (FX2 PA2)
GND 8- -9 S2 (FX2 PA3)
(GND) Y4 1-   O -16 VCC
(GND) Y6 2- -15 Y2
(lower EL5166, IN-) Z 3- -14 Y1
(GND) Y7 4- -13 Y0
(GND) Y5 5- -12 Y3
(GND) E# 6- -11 S0 (FX2 PA4)
VEE 7- -10 S1 (FX2 PA5)
GND 8- -9 S2 (FX2 PA6)

S2 S1 S0 74HC4051D Mux VDIVs (vendor software)
0 0 0 Y0 to Z 200mV
0 0 1 Y1 to Z 500mV
0 1 0 Y2 to Z 5V, 2V, 1V
0 1 1 Y3 to Z 100mV, 50mV, 20mV

Intersil EL5166 (both) pinout:

NC 1-   O -8 CE#
(upper/lower 74HC4051D, Z) IN- 2- -7 VS+
(AD8065, IN-/VOUT) IN+ 3- -6 OUT
VS- 4- -5 NC

Microchip 24LC02BI (both) pinout:

(Low, but not GND) A0 1-   O -8 VCC
(GND) A1 2- -7 WP (GND)
(GND) A2 3- -6 SCL (FX2 SCL)
VSS 4- -5 SDA (FX2 SDA)

Analog Devices ADS9288 pinout:

AD9288 pins Description
S1, S2 S1 depends on FX2 PA7 (see below), S2 is tied to GND.
DFS Tied to GND. Data format select = "offset binary" (not "twos complement").
AINA, AINB Analog input channels.

Cypress FX2 pinout:

FX2 pins Description
CTL0 Connected to AD9288 ENCA and ENCB and FX2 IFCLK.
PB0-PB7 Connected to AD9288 D0A-D7A and SN74LVC16245A 1A1-1A8.
PD0-PD7 Connected to AD9288 D0B-D7B and SN74LVC16245A 2A1-2A8.
PA7 Connected to the SN74LVC16245A's 1OE# and 2OE# pins (both 8bit groups share the signal) as well as 1DIR and 2DIR. Also connected to the ADC's S1 pin (via two discrete inverters with R37, Q2, R13, Q1).

This means PA7 selects between digital (low) and analog (high) data paths, data is always at FX2 ports PB and PD, and either carries 16 digital channels, or two eight bit analog channels.

The benefit of "variable DIR" in the SN74LVC16245A is questionable, since it shares the signal with OE# and for high levels the output is high-Z anyway -- so the ADC output is not routed to digital pins when PA7 is high, not tying DIR to a fixed level is pointless(?)

PA7 Description
1 Selects scope mode. The ADC's S1 pin is high, which means "Normal operation, data align disabled". The SN74LVC16245A's OE# pins are high ("don't enable output", DIR state is irrelevant).
0 Selects LA mode. The ADC's S1 pin is low, which means "Standby both channels A and B". The SN74LVC16245A's OE# pins are low ("output enable") and the DIR pins are low ("B data to A bus", i.e. data direction is from LA connector to FX2).
PC2 1kHz probe calibration pin.
PC0/PC1 Dual-color (red/green) LED.
PC1 PC0 LED
0 0  ?
0 1 green
1 0 red
1 1 off

Protocol

See Hantek 6022BE#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).
