PDL-200A with dual electromechanical trombones-Image

Precision Programmable Electrical Delay for RF/Microwave Frequency Signals

The PDL-200A combines dual electromechanical trombones internally in series to extend the total delay range to a maximum of 1.25 nanoseconds. In one single unit, the PDL-200A offers the same resolution (to 0.50 ps step size) as the PDL-100A while doubling the total delay range of the instrument. The PDL-200A is equivalent to two PDL-100A's in series but in half the size and with only one unit to command and control.

For demanding applications where completely wideband passive delay is required across the entire signal path, the PDL-200A offers industry leading performance.

The PDL-200A's 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.

The PDL-200A is fully programmable via GPIB (IEEE488.2), Ethernet TCP/IP, and RS-232 Serial interfaces or via the optional Microterminal (MT-100A).
