HPDL-1A Colby Instruments Programmable Delay Line InstrumentDelays are created with a low-loss microwave clad material with RF relays attached directly to the printed circuit (PC) board. The HPDL-1A offers excellent performance from DC to 600 MHz at maximum delay, and is usable to 1000 MHz. The minimum resolution is fixed at 10 ps, and Maximum Delay Range is 10.23 ns. The unit comes with Manual Control on the Front Panel of the instrument, GPIB (IEEE488.2), and RS232 Interfaces standard.

NOTE: The HPDL-1A has been superseded by our newer HPDL-100A Series of instruments offering additional features and functionality.  The model HPDL-1A will no longer be available after June 30, 2006.
