Shb - Thin-Film Hysteresis Loop Tracers

 

The MESA is the only hysteresis loop tracer on the market that can make measurements in the frequency range of 10 Hz and below. Competing units operate with more-easily generated 60 Hz drive fields, and can have errors of as much as 30% in coercivity (Hc) measurements.

 

This latest generation instrument is fully computer controlled and capable of displaying and measuring hysteresis (BH) loops, magnetoresistance (MR/GMR), and magnetostriction.

 

The MESA is controlled by a PC running Microsoft Windows XP, and uses internal DSP processors for high-speed waveform generation, digitization and processing. All instruments are equipped with a "pattern memory" feature to digitally cancel ambient magnetic fields and allow for operation at extremely high sensitivities, even in relatively noisy magnetic environments. When equipped with the Digital Signal Processing option, any remaining noise can be dramatically reduced by sophisticated digital filtering algorithms.
