Product Overview of Programmable Delay Line (PDL)
Instruments
Colby Instruments' Programmable Delay Line (PDL) Series instruments offer
precision programmable
electrical delay for RF/microwave frequency signals in one easy to setup and use instrument. Our newest
PDL-100A Series of instruments utilize
our patented Electro-Mechanical Trombone structure
and can be configured in different models to offer total delay up to 100 ns
or more. Delay precision accuracy and resolution to 0.50 ps lead
the industry in performance.
All programmable delay line instruments are suitable for use in high frequency RF signal
applications as phase shifters or where an extremely high precision
and accurate amount of delay is required.
The CPDL-100A Series offers a
customizable instrument with custom programmable fixed delays utilizing
Aerospace grade microwave relays and precision-cut semi-rigid coaxial cable. The CPDL-100A is fully customizable based on customer specifications for delay resolution (to the smallest step size of 10 ps) and total delay range up to a maximum of 200 ns.
It is best suited for applications where total range of delay is a
higher priority than delay step (or phase shift) resolution.
The new value priced HPDL-100A offers a delay range from 0 to 10.23 ns
with a fixed minimum resolution or step to 10 ps.
Each unit includes GPIB (IEEE488.2), Ethernet TCP/IP LAN and RS-232
Serial interfaces for remote programmable control. An optional
MT-100A Microterminal (LCD display and numeric keypad) offers manual
entry of desired delay. A Rack Mount Option (RMO-1) is available for mounting any
one of our entire line of instrument models into a standard 19" rack.
All units can be used as delay lines or phase shifters suitable for both analog and digital applications and free from all noise sources, including no Phase Noise and no Jitter. For analog applications, bandwidth is from DC to 18
GHz. For digital applications, DC to 40gb/s NRZ. Phase shift
resolution is to 0.18 degrees per 1GHz frequency of signal input.
