High Speed Pulse Generator Circuit

The shift register is programmable to produce a pulse train of trigger pulses that defines a frame s shutter duration and that further defines an interframe time between triggers for all frames.

High speed pulse generator circuit.

Their input voltage range is from 1 3 to 15 volts peak. The pattern generator circuit comprises a high speed shift register and a non overlap generator. This high voltage and high speed integrated circuit can also be used for piezoelectric capacitive or mems sensing in ultrasonic nondestructive detection and sonar ranger applications. U1 and u2 are identical high speed comparators and will accept any wave shape from dc to 1 mhz.

It is an ideal synchronization and timing control instrument for electronics and lasers. With a 12 6 volt input the ignition coil model delivers its maximum pulse but a unique multivibrator driver circuit makes operation possible down to a supply voltage as low as 1 5 volts yielding an output pulse of only a few hundred volts. U3a is the burst length generator and will send out one group of pulses every time s1 is depressed. This pulse delay generator generates high frequency pulses digital delays and bursts.

As integrated circuits ics speed up the rise fall times of most pulse and function generators 5ns typical become inadequate for measuring time intervals below 20ns. Its pulse frequency is set by a front panel control with a range from about 0 3hz to 20 hz. The input impedances are one megohm. It is designed for portable medical ultrasound applications.
