CW-EPR Digital Upgrade

Today the next level of a new digital generation of CW-EPR spectrometers is available for your current EMX/ELEXSYS transputer system, bringing you a host of new benefits.

ELEXSYS

Improved 32 bit Amplitude Resolution, Fast Digitizer and Rapid Scan Acquisition

As a digital lock-in, the SPU provides unparalleled detection and digitization of both large and small signals with the same receiver gain, in a single scan. The SPU also functions as a fast digitizer for transient acquisitions and as a rapid scan driver for extremely fast field sweeps.
Lock-in:

  • Simultaneous detection of up to 5 harmonics
  • Absorption and dispersion channels
  • Up to 10 microsecond resolution for time scans

Signal Processing Unit (SPU)

Fast Digitizer

  • 125 MHz sampling rate
  • 64 k on-board averages
  • 16 k points in time domain

Rapid Scan

  • 200 G sweep range
  • Up to 16 k points

Field Resolution up to 256000 Points

Very high magnetic field resolution for both narrow and wide sweep ranges. The number of points in the field sweep experiment can be varied continuously from 2-256000 points.
