[en] Precision multi-channel programmable pulse generator (PPG) finds applications for trigger and synchronisation in FEL injector system. This system can be used to provide master trigger signal, along with programmable edge arrival delay and pulse width both, to synchronize various RF sub systems. To fulfil this requirement indigenously a precision programmable pulse generator unit has been designed and developed. Stabilized Internal time base is embedded in the unit to provide reference signal up to 10 MHz. The unit can also accept external RF reference signal at 10 MHz. Using a high frequency zero crossing detector circuit, RF reference gets converted in to TTL compatible unipolar pulse train. Through the frequency divider, pulses at 10 MHz are brought down to frequency in the range of 1 to 10 Hz. This low frequency signal is used as a master trigger pulse for the different sub systems. Master trigger pulse serves as input to programmable pulse generator circuit. Pulse edge delay as well as pulse-width of the master trigger pulse can be varied up to 80 µs with the resolution of 20 ns. Micro-controller is used as local controller and unit can be interfaced with remote PC through RS 232 interface or blue tooth. Line driver at the output is used to drives 50 Ω coaxial line and also maintains rise time better than 2 ns. To provide galvanic isolation, output is also made available simultaneously through on optical fibre port. Peak to peak jitter observed is better than 1 ns. An accuracy of ±0.01% of full scale is achieved for both the edge delay and pulsewidth. (author)
