The Hantek PSO2020 is a USB-based, 1-channel oscilloscope with an analog bandwidth of 20MS/s and 96MS/s sampling rate.

See Hantek PSO2020/Info for more details (such as lsusb -v output) about the device.

Hardware


Microchip 24LC02BI 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=VCC, S2=GND. "Normal operation, data align disabled".
DFS Tied to GND. Data format select = "offset binary" (not "twos complement").
AINA, AINB Analog input channels.

Cypress FX2 pinout (TODO):

FX2 pins Description
CTL2 Connected to AD9288 ENCA and ENCB and FX2 IFCLK.
PB0-PB7 Connected to AD9288 D0A-D7A.
PD0-PD7 Connected to AD9288 D0B-D7B.
PA7 High Voltage Rele'
PC6 Green LED.
