Transition Time Converter, 250ps
15432B
-
The new design of these transition time converters ensures very low signal reflection far beyond the 3 dB point, unlike conventional converters. Reducing the signal transition-times also increases the overall pulse-performance for overshoot/reflection sensitive applications. The converters are fitted with SMA connectors, one male, one female. These converters have been designed to convert the fixed transition-times of the Keysight 8133A 3 GHz timing generator (<100 ps transitions) to slower, fixed transition-times (150 ps, 250 ps, 500 ps, 1 ns, 2 ns) hence reducing the signal bandwidth. All transition-times are from 10% to 90% of amplitude.
