The Lecroy 821 Quad 100 MHz Discriminator is a high performance Quad Discriminator incorporating the
features requested by experimenters throughout the world. The reliability designed into the
821 is based upon LeCroy's experience with its last three generations of quad
discriminators. Its advanced hybrid front ends afford high sensitivity and greater than 100
MHz counting rate capability. Output pulse width stability is excellent even at threshold.
Each channel has its own threshold and width controls, 5 NIM outputs, 1 ANTI-NIM output
and a Rate Lite. Threshold may be monitored at a front-panel test point.
The output duration of the 821 may be adjusted over the range 5
nsec to 1 usec. In the updating mode, a threshold crossing extends the output pulse duration by a time
equal to the selected pulse width. If the second threshold crossing occurs within the 9 nsec
double-pulse resolution, the unit will not respond.
If, in a train of input pulses to a discriminator, the pulses are separated by less than
the resolving time, the discriminator output will be extended until the falling edge of the last pulse in
the burst. This is a particularly important feature in veto applications.
Rate Lite is an indicator LED. It produces a flash for each discriminator firing. A stretching circuit
allows single firings to be discerned.
Common Veto provides the option of inhibiting all channels simultaneously, by application of a NIM
fast pulse. This is an effective means of eliminating unwanted background early in the logic system.
The 821 LeCroy Quad Discriminator may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
