Number of channels available :

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

Properties of channels :

• Configurable voltage and time base.

• 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 filter for spike acquisition (bandpass filter with a low cutoff frequency of 300 Hz and high cutoff frequency of 6 kHz and a order 4).

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.

• Report View: Users can generate reports with information about the experiment (Date,Experiment description, etc.) and acquisition plot.

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