Multi-Parameter Analyzer List Mode

The multi-parameter analyzer (MPA) system is designed as a list mode with USB2 and USB3 ports for data transfer at high speed. First, data can be stored on the FIFO and then is transferred to a PC through a USB port. Application program can be simultaneously displayed single and multi-parameter spectra.

Multi-Parameter Analyzer List Mode Model 4200

  • Connect to PC via USB
  • 1 Mbyte of SRAM memory
  • Connect up to 3 external ADCs with 8 K maximum gain
  • Operational modes:

Single independent: In this mode, each ADC works independently of other ADCs

Single dependent: In this mode, the specified ADCs are synchronized and the buffer information is displayed separately.

Multiple: In this mode, the specified ADCs are synchronized, and their data is displayed in a buffer as a matrix.
