The picosecond delayer is a module designed and manufactured by Micro Photon Devices (MPD) that is capable of generating output pulses (both NIM and TTL) with user-selectable delay and output pulse duration, in respect to the rising or falling edge of an input signal.
The delayer is completely based on solid-state components and features a 50 ns nominal full scale range with a 10 ps step delay resolution, whilst the pulse duration is also user controllable from 1 ns to 250 ns with a nominal step of 3.3 ns.
The excellent integral non linearity error is comprised between +50 ps and -100 ps over the full scale range and for all operating temperatures. This exceptional performance makes the picosecond delayer the perfect choice for any experimental set-up where signals must be delayed with high accuracy and stability of characteristics over a broad range of delays and temperatures. The low random jitter makes it also applicable to Time-Correlated Single Photon Counting applications.
The picosecond delayer is available either as standalone module or as OEM electronic board. In this latter case the delayer can either be controlled through a very simple software interface or, since the commands are ASCII strings sent over a virtual COM port, by any user-made program able to communicate over such a port.
