PDL-100A

Electromechanical trombone with incredible precision

PDL-100A offers high-resolution electrical delay based on the Electromechanical Trombone delay line structure.  The base model PDL-100A-625.0PS offers total delay from 0 to 625.0 ps and signal input bandwidth from DC to 18 GHz. Additional models in the series offer up to 100 ns of delay or more depending on customer requirements.  Typical models with delay extensions are at 1.25 nanosecionds (ns), 10.0 ns, and 20.0 ns of total delay.

An internal stepper motor produces precise delay steps with a resolution to 0.5 ps when operated in series connected single channel mode. The patented Electro-Mechanical Trombone design has an outstanding operational lifetime with a recommended service interval of 500,000 operations. Precision and accuracy is to 0.1%, ± 0.2 ps.

In the standard set-up (series connected), two identical 312.5 pstrombone sections are connected in series via a short semi-rigid coaxial cable accessible at the front panel. The series connected configuration provides a full delay range of 625.0 ps with 0.50 ps step resolution. Alternatively, if the short semi-rigid coaxial cable is removed to single channel (parallel connected) operation, two very tightly phase matched delay lines are available each with a total delay range of 312.50 ps and a higher resolution of 0.25 ps.

The PDL-100A is fully programmable via GPIB (IEEE488.2 protocol), Ethernet TCP/IP, RS-232 Serial interfaces or via the optional Microterminal (MT-100A). At 18 GHz, the frequency roll-off is typically less than 1.0 dB. Customers have used this delay line for digital applications up to 40 Gb/s NRZ with excellent results. This delay line is unmatched in performance, resolution, and repeatability by any competing product on the market.
