Skybox Advantages

Competent and Easy

Skybox is a state-of-the-art solution specially designed for NCS, EMG and EP studies. It combines easy-to-use interface, advanced software features and options and wide neurophysiological diagnostic capabilities. It can be used for the routine tests, in operating rooms and intensive care units.

Quick EMG Acquisitionе

With Skybox NCS, EMG and EP acquisition became an extremely easy and quick process. The dedicated keyboard, the footswitch and, above all, the specially developed Neuro-MEP.NETω software allow recording NCS and EMG very quickly.

All Modality EP Recording

Skybox has built-in stimulators to record EP of all modalities and the full-featured software that makes this process quick and comfortable:

  1. The unique averaging algorithms, such as, for example, weighted averaging algorithm considering the waveforms of the native traces, allow decreasing averagings in 3-5 times to obtain the good response.
  2. “Non-modal acquisition” option allows a user to fulfill other actions (for example, process the data being recorded) during EP acquisition.
  3. Automatic search of peaks and arrangement of EP component markers can be done both by specially developed algorithms (depending on EP modality) and specified latency ranges.


The device combines:

  • five-channel amplifier
  • two independent electrical stimulators with 4 outputs
  • auditory stimulator
  • visual stimulator
  • pattern-stimulator
  • keyboard

They are placed in a book-size case (212×180×57 mm) and weight not more than 1 kg! You will need only the electrodes and a computer (notebook) to start the examination!
