The Microterminal (MT-1A) provides convenient keypad entry for manual control of delay for the Delay Line Models PDL-1A, PDL-10A, PDL-30A, and CPDL-Series. The MT-1A allows for convenient operation of the PDL located side-by-side on a work bench. The PDL delay settings can be controlled simultaneously in both Local mode (manual) and Remote mode (GPIB control). No switch setting is requir... (read more)

Programmable delay or phase shift instrument at an amazing value! The new HPDL-100A utilizes precision cut semi-rigid coaxial cable and Aerospace grade microwave relays to offer delay from 0 to 10.23 ns with a step precision to 10 ps. Input signal bandwidth is from DC to 12.5 GHz. (read more)

The PDL-10A Programmable Delay Line instrument from Colby Instruments is based on the Electro-Mechanical Trombone delay line structure and 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. (read more)

PIN Diode Modules offer programmable delay (phase shift) to 1 ps resolution and 5.12 ns total range. Combine three modules (P1-PDM, P2-PDM, and P3-PDM) for a total range to 5.12 nanoseconds. TTL/CMOS level interface.

Each module requires +12V and +5V power. (read more)

Numerical Aperature (N.A.) of 0.39 and hard polymer cladding that allows a high core-to-clad ratio, the Superguide™ SPCH is the low cost fiber of choice. The pure fused silica (SiO2) used in the core of the Superguide™ fiber is made by reacting silicon tetrachloride (SiCl4) with oxygen (O2) using an oxy-hydrogen flame resulting in superior ultraviolet (UV) to visible (VIS) (read more)

When looking for a silica core and silica clad fiber with a hard polymer coating that allows a high core-to-clad ratio and a numerical aperture (N.A.) of 0.22 for efficient light coupling, the Superguide™ SFSH is the fiber of choice. The Superguide™ fiber is drawn from preforms manufactured by the Plasma Outside Deposition (POD) process. (read more)

When looking for a fiber with a high numerical aperture (N.A.) for more efficient light coupling, the Superguide™ PCS is the low cost fiber of choice. The pure fused silica (SiO2) used in the core of the Superguide™ fiber is made by reacting silicon tetrachloride (SiCl4) with oxygen (O2) using an oxy-hydrogen flame resulting in superior ultraviolet (UV) to visible (VIS) transmis (read more)
