The Model N413 A is a one unit wide NIM module housing 8 independent non-updating discriminators.
The threshold of each channel can be set in the range -20 mV to -1 V
via front panel trimmers. The value of the threshold can be monitored on
a front panel test point. Three DIP switches allow to select the channel
whose threshold is present on the test point. For each channel it is possible
to adjust the output width in the range 5 ns to 150 ns via front panel trimmer.
Each channel has two NIM outputs in normal logic and 1 NIM output in
complementary logic. The "SCOMM" is an analog output which supplies a current
of -2 mA per channel over the relevant threshold. A common VETO input signal
disables the output signals of all the channels.
