This high-resolution delay line based on the Electro-Mechanical Trombone delay line structure has a total delay range from 0 to 625 ps and bandwidth from DC to 18 Ghz. An internal stepper motor produces precise delay steps with a resolution to 0.5 ps when operated in series connected mode. The patented Mechanical Trombone design has an outstanding operational lifetime of 500 000 operations and an absolute accuracy of 0.1% 0.2 ps.
