  DUAL COMPARATOR/WINDOW DISCRIMINATOR



 

Product Code: V21-10
Contact our Behavioral Research Specialists for more information

Description
 
The V21-10 can be configured as a single channel voltage level detector with a remote reference voltage, two independent voltage level detectors (Schimidt Triggers), or as a single channel Window Discriminator.  As a single channel comparator or level detector, a remote voltage (e.g., from a D-A Converter, an output from a BioAmplifier or Coupler, etc.) can be applied to either channel at the “Reference Voltage” input and the signal of interest applied to the other channel.  This provides programmable control if the reference signal is coming from a D-A Converter or comparison to another physiological signal if the reference voltage is coming another physiological channel.

In the dual channel mode, signals from two independent sources can be used and the reference voltage amplitude and polarity are set by manual controls.  When used as a level detector, the V21-10 provides simultaneous digital outputs indicating when the signal has exceeded the reference voltage and when the signal is below the reference voltage.

As a Window Discriminator, the upper and lower reference voltages and the polarity of each voltage are manually set.  As with the two Comparator modes, there are two digital outputs, one indicating when the signal is within the window and one indicating when the signal is out of window (either exceeding the upper reference voltage or less than lower voltage).
