Window Discriminator module

• Monitor signals and discriminator levels simultaneously at the multiplex output
• Delay line 2.5 ms
• Audio output selectable (Within/Above /Raw)
• Control with software

For every waveform peak that appears “within” the window aperture set by the user, a pulse is generated at the “Within Window” output. Signals that exceed the upper level of the window produce a pulse at the “Above ” output. Both the input signal and the window aperture settings are visible at the multiplex port as shown below in the upper trace. By viewing the input signal as well as the “window” discriminator levels at the multiplex port provides a convenient visualization and ease in setting up an experiment. you can set the lower and higher levels by computer control with a 2.5mv precision 

 The pulses from either output (Within Window or Above Window) are generated by the falling edge of the analyzed signal as it crosses the preset levels.

The diagram above shows the multiplex signal output with the widow parameters displayed on the input signal. A “within” pulse occurs at the lower level crossing point after the input signal is measured within the boundaries of the settings and an “above” pulse is generated for those signals going above the upper level setting. you can record  Above or Within output as spike activity.

you can select audio output and listen to raw signals or within or above pulses by a external speaker.
