The FMC DEL 1ns 4cha delay module is a mezzanine card according the FMC (FPGA Mezzanine Card) standard and will take in a TTL trigger signal and will send it out to four different outputs. The delay from the trigger input to each of the outputs can be set independently in a range from 500 ns to 120 seconds. It is implemented using a dedicated time-to-digital converter.
Modes of operation:
Pulse delay: a pulse coming to the input triggers generation of a pulse or series of pulses of given width and repetition rate on chosen outputs after a certain time programmed by the user (see fig. 1a).
Single channel TDC: time tags of incoming pulses are provided to the user via a circular buffer.
Pulse generator: produce a pulse or a series of pulses of arbitrary length and repetition rate starting at a given UTC/TAI time
