WD-2

Time/Amplitude Window Discriminator and Event Detector (Dagan)
Beschreibung

The WD-2 is a versatile, inexpensive, yet easy to use tool for conveniently sorting waveforms by amplitude and time criteria, providing 5 volt digital outputs corresponding to several criteria. After a delay, the digital output goes high when the input signal enters the amplified window.

 

Features

Simultaneous multiplexed display of signal, window levels, and Minimum Time (TIME MARK)

Minimum delay time criteria (10 µs to 100 ms)

Windows amplitude (APERTURE) is independent of  BASELINE setting

Can be used as a simple Two Level Detector
The >BASELINE and >APERTURE output BNC's are digital levels that simply indicate signal greater than each of the two levels. They are not affected by MINIMUM TIME, and both can be high if signal exceeds both levels.

Can be used as an Amplitude Window Discriminator with Time Delay before acceptance
The ACCEPT output BNC only goes high when the INPUT signal exceeds the BASELINE and the MINIMUM TIME, and does not exceed the APERTURE. The MINIMUM TIME feature eliminates the acceptance of slowly rising signals that will eventually exceed the upper window level (APERTURE), or slowly falling signals going back through the APERTURE.
