Digitimer DS7A Constant Current Stimulator

A DS7A constant current stimulator from Digitimer is available for recording various magnetic evoked fields.

• Magnetic evoked fields under stimulation:
  • Somatosensory Evoked Fields (SEF)
  • Auditory Evoked Fields (AEF)
  • Visual Evoked Fields (VEF)
  • Language Evoked Fields (LEF)
• Magnetic evoked fields under voluntary activity:
  • Motor Related Fields (MRF)

Improper installation of the DS7A can result in an increase in sensor noise levels due to RF leakage and/or unwanted ground loops.

Guidelines to MEG Data Acquisition (Customer training, May 2020) provides more information.

The DS7A is located in the Stimulus Cabinet.
