 The Custom Programmable Delay Line (CPDL-100A) offers custom programmable delay at customer specified delay step and total delay range limits. The CPDL-100A does not use the
Electro-Mechanical Trombone delay line structure, but is made entirely from precision cut phase-matched semi-rigid coaxial microwave cables and coaxial relays. The CPDL-100A is an excellent fit
in signal applications where resolution to 10 ps step size or larger is adequate or where extended total delay up to 200 ns is required.
A step size (or delay step) can be defined as small as 10 picoseconds (resolution) and can go up to several nanoseconds. Up to 16 binary step delay sections can be defined. Total delay range limit defines the maximum total delay of the unit and can be as high as up to 200 nanoseconds.
Typically, a CPDL-100A
instrument is specified where each of the up to 16 delay sections is a binary multiple (2x) of the previous. For example, a CPDL-100A specified at 100 ns total delay range, with 1 ns minimum step delay would have: 1 ns, 2 ns, 4 ns, 8 ns, 16 ns, 32 ns, and 37 ns delay steps specified. This allows any 1 ns step to be specified between 0 to 100 ns using a combination of the defined delay steps.
Bandwidth and pricing vary depending on the number of relay sections defined and total length of delay needed.
Phase Matched Units
For applications where phase matched units are required (e.g. with differential signal
inputs), we are able to manufacture dual units at the same time and offer precision cut phase-matched coax on each and every section of delay. With the two differential signals split between each unit, each signal will experience the same amount of delay as the other unit and is critical in phase matching applications.
Delay Ranges (non-contiguous)
A delay range goes NOT have to contiguous (e.g. from 0 to 50 ns
continuous). With our CPDL-100A, we can customize any solution with non-contiguous delay sections and each section can have a custom delay value. Individual sections can be switched off or on as delay is required. Total delay will be the sum of each of the delays that are switched on and is programmable. Each CPDL-100A has an embedded microcontroller so making special or custom models specific to your unique application is
relatively straightforward. Please contact us directly to inquire about building a custom solution that will meet your application requirements.
