The PM 5771 provides pulses at a repetition frequency of 1 Hz to 100 MHz. The pulse transition time is variable between 2.4 ns and 100 µs. Other important pulse parameters such as delay and duration are variable from 5 ns to 100 ms. The PM 5771 can also be triggered or gated externally, generate double pulses or operate in the single shot mode. The output pulse can have positive or negative polarity and be inverted to obtain a maximum duty factor. Ad.c. offset can also be introduced. This variety of operating modes combined with the wide transition time range and an 80 mV - 10 V output amplitude make the PM 5771 particularly useful when testing or simulating various types of logic circuits, such as CML, Schottky-TTL or HNIL. Other application areas include test of delay lines and magnetic memories, or simulation of pulse degrading.
