The Hantek DSO-2090 is an inexpensive USB-based oscilloscope. It has 2 channels, an analog bandwidth of 40MHz and 100MS/s sampling rate.
See Hantek DSO-2090/Info for more details (such as lsusb -vvv output) about the device.
Hardware
- Xilinx XC95288XL CPLD
- 50 MHz oscillator
- 2 x ISSI IS61LV256 (32K SRAM)
- 2 x HEF4052B (dual 4-channel analog mux/demux)
- Cypress CY7C68013a (FX2)
- Microchip 24LC02B (2K EEPROM for the FX2)
- Calogic SST5912 (N-Channel Monolithic JFET)
