PX Ultra Controller

The new digital controller PX Ultra turns your routine SPM device into easy-to-use instrument for scientific breakthroughs and advanced research.

Innovative Research

  • The controller has 5 lock-ins amplifiers for up-one-level multi-technique leading edge measurements.
  • The up to 5 MHz bandwidth for use of HF cantilevers and high harmonic oscillations’ action for the advanced investigation of electrical and mechanical properties at nanoscale.
  • Low-noise piezoscanner control affords carrying out research by the same scanning element in the range from nanometers to tens and hundreds of micrometers.

Onward progress

  • Ease of upgrade and functional extension of controller due to convenient slot organization.
  • Regularly updated software.
  • LabView compatibility for users’ custom applications.
  • HybriD Mode™-compatible.

Operational comfort

  • Fully automated adjustment for defined measuring mode.
  • Digital and analogue peripheral ports.
  • Ask on-line support service.
