SKU: HS502 Category:


An improved version of the popular HS402 DIY Oscilloscope, but ready-to-use and with new core-technology.
It integrates a new ARM® Cortex®-M4 MCU (released in 2022) with high-speed ADC up to 13MSa/s.

Main features

  • 2 Channels
  • ADC resolution: 8 – 12 – 16 bit
  • AC/DC Coupling
  • Hardware Trigger
  • Max rate: 13MSa/s – 8 bit, 6.5Msa/s -12 bit
  • Max input range: 16Vp
  • Max supported voltage (protection): 50Vp.
  • Memory buffer: 64KB (at least 8000 Sa/channel for 2 channels on)
  • HScope basic license for this oscilloscope is already included. Moreover it is possible to use the Automotive Module without Automotive license.
