The AV-107 series of pulsed constant current generators is designed for pulsing microwave & laser diodes and other loads requiring a very high source impedance and fast rise times. The AV-107 series features an output current change (or regulation) of less than +/-5% for a load voltage change from 0 to 60V. Model AV-107B-B provides a peak output amplitude that is ariable in two ranges from 0 to 200 mA and 0 to 2 A, with a pulse width from 20 to 200 ns and a 10 ns rise time, at frequencies to 20 kHz.
