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

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.
