AVTECH AVX-FD2-PS

The AVX-FD series of digital frequency dividers will divide the pulse repetition frequency of an input pulse train by a factor (N) which is variable (in steps of 1) up to 255, 999, or 65535, depending on the model. All three models will accept input frequencies of up to 250 MHz. The AVX-FD1-PS and AVX-FD2-PS models are designed to work with TTL logic-level input signals (an ECL logic-level option is available). The output pulse width for Model AVX-FD1-PS is variable from 50 ns to 50 us using a three-position range switch and a one-turn control, and the output frequency is limited to 5 MHz. The output pulse width for Model AVX-FD2-PS is also controlled by a 3-position range switch and a one-turn control but is variable from 5 ns to 5 us, with a 50 MHz output frequency limit. If the divisor (N) is set to 1, these models will act as pulser-stretchers, with the output pulse width controlled by the front-panel controls. For both models the input impedance may be set at either 50 Ù or 1 kÙ by means of a two-position switch.
