WD-1000 Time/Amplitude Window Discriminator


The window discriminator is used to separate single neuron action potentialsfrom multi-unit recordings. It can operate as a classic voltage amplitude windowdiscriminator, or as a time/amplitude discriminator. In the latter mode, the signal must fall within a voltage and an adjustable time window. This permits separating similar pulses that differ only in timing. Outputs are available from both window levels, a data output, and an independent trigger output for synchronizing the oscilloscope trace. These outputs allow simultaneous discrimination of three signals.

icone-feat.gifStandard Features:

• Voltage or time/amplitude window, multiplexer and scope trig outputs
• Separate outputs for each level crossing

icone-area.gifApplications:

Discrimination of single units from multi-unit recordings

LED indicators show which alarm condition exists, and a beeper (switchable) provides an audible warning. Digital meters show signal voltage, which can be calibrated to reflect “real-world” measurements. Logic outputs are provided for all alarms, and are accessible on the rear edge-card connector.

icone-feat.gifStandard Features:

• Wide input range, adjustable high and low alarms
• Logic outputs for external control or monitoring of alarms
