Description
4 channel fast discriminator with (dual PECL comparator) and MAX537 (4x serial DAC). This module has 5 lemo connectors
This module has 4 comparators (MAX9601), the threshold and hysteresis can be set through a register (used DAC MAX537). The channel 1 is an exception, an external threshold can be set using the lemo connector TH1, to do this you have to use solder two jumpers in the pcb.
If you do not want to use all comparators, the lemo connectors can be used as standard LVTTL input/output DIO1..DIO4. You can use maximal 4 DIO, the channel AI4 is always a comparator input. Each DIO has a 50 Ohm resistor at the input, if you want to use the DIO as input you can solder this resistor to avoid reflections.
Note: The version 0 is a prototype and it is not working
