Dow-Key Microwave (a subsidiary of Dover Corp., NYSE:DOV), is an AS9100 and ISO 9001:2000 certified manufacturer of electromechanical coaxial and waveguide switches, Switch Matrices, Integrated Modular Assemblies, and related passive components. Dow-Key”s newest product offering is the Custom Programmable Delay Line Instrument.

The 8001 Programmable Delay Line Instrument offers wideband electrical signal delay and precision programmable control in one easy-to-setup and use instrument. Total delay is custom configurable up to 200 ns, and minimum step size resolution is 10 ps or 3.6 degrees per 1 GHz input signal frequency. Instrument control supports GPIB (IEEE488.2), Ethernet TCP/IP and RS-232 interface protocols.

The design of this instrument targets both R&D and ATE requiring high precision delay with programmable control in timing and synchronization, phase shifting, and noise cancellation applications.
