Number of channels available :

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

• Each channel can be configured independently of the others.

Properties of channels :

• Variable sampling rate on all channels.

• Variable number and location of each channel on the panel.

• Variable sampling period.

• Configurable voltage and time base.

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

• 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.

• Fix button to freeze the acquisition without stopping the application.

• Print mode : open a panel to configure the print. It is available a position cursor and an Autoscale button.

• 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.
