Description

These series of Digital Oscilloscopes use a standard ARM9 processor and are shipped with linux. The various models can be hacked to add additional features. These pages aim to document as much as possible to foster a wider community of developers for these DSO's.

General

Components

  • 7" 800 x 480 color LCD Display
  • Samsung S3C2440 ARM9 System On Chip (SoC)
  • ISSI IS42S16160C-7TLI SDRAM (2 x 256Mbit = 64Mbyte)
  • Samsung K9F1208U0C Nand Flash (1 x 512Mbit = 64Mbyte)
  • ISSI IS61LPS25636A static ram ( 1 x 9Mbit = 1.125Mbyte)
  • Altera MAX-II EPM240T100C5N CPLD (complex Programmable Logic Devices)
  • 4 x Analog Devices AD9288 ADCs (yes, for 1GSs overclocked to 125MHz in 8ns, 4ns and 2ns time base - like Instek GDS1102A)
  • 2 x Analog Devices AD8370 amps (750MHz bw - input stage like Rigol)
  • 2 x TI LMH6552 amps (1.5GHz bw - input stage like Rigol)
  • ADCMP562 ECL comparator (for trigger)
  • Altera Cyclone III FPGA (ADC sampling control and data acquisition)

Firmware

  • Linux Kernel version 2.6 from reports
  • need more details and bootlog

Open Linux Support Todo List

  • lodge a GPL compliance complaint against Hantek
  • get u-boot working
  • get current 3.x kernel booting
  • cpld interface driver
  • lcd display driver
