BIOTEP

Description :

BIOTEP® is an acquisition and signal processing software intended for event-driven like Evoked Biopotential or Spikes. It includes features like four different triggering mode, FFT analysis, waveform saving and so on.

Specifications :

Number of channels available :

  • 16 channels (designed for use with the National Instruments Card model 6023-E).  

  • Each channel can be configured and activated independently of the others.

Properties of channels :

  • Configurable voltage and time base.

  • AutoScale button: Adjust automatically all the active channels in the front panel.

  • A configurable trigger. Mode, level, channel trigger and others parameters can be adjust to acquire the events.

  • Acquired block of data can be viewed in a number of different formats. Data can be saved in either a proprietary format to conserve disk space or in a text mode for importation into other software packages.

  • Specific filters for each channel (lowpass, highpass, bandpass, and a bandstop filter with a cutoff frequency from 0.1 Hz to 10 kHz and a configurable order).

The filter type is a Butterworth Filter. It is characterized by a smooth response at all frequencies and a monotonic decrease from the specified cutoff frequencies. Butterworth filters are maximally flat-the ideal response of unity in the passband and zero in the stopband.

The advantage of Butterworth filters is a smooth, monotonically decreasing frequency response. After you set the cutoff frequency, BIOLOGGER® Acquisition Tools sets the steepness of the transition proportional to the filter order. Higher order Butterworth filters approach the ideal lowpass filter response.

 

Several Tools :

  • Load View: This tool permits to load a file to see in the graph and to adjust the several scale.

  • Average View: In this windows, users can see the average of all scan channel per channel with the five ultimate scans. In the final, it can be see all the average of active plot.

  • Report View: Users can generate reports with information about the experiment (Patient's Information,date,etc.) and average plot or acquisition plot.

  • FFT View: In this windows, users can see Fast Fourier Transform of one channel. User can select several parameters: display (dB or Linear), window (None, Hamming, etc.) and unit (Vrms, Vpk, etc.).
