Our Programmable Delay Lines Offer Unparalleled Precision

Electro-mechanical trombone with incredible precision. 

The base model PDL-100A-625.0PS offers total delay from 0 to 625.0 ps and signal input bandwidth from DC to 18 GHz. Additional models in the series offer up to 100 ns of delay or more depending on customer requirements.  Typical models with delay extensions are at 1.25 nanosecionds (ns), 10.0 ns, and 20.0 ns of total delay.

PDL-100A

Engineers have used this delay line as a phase shifter in noise cancellation loops and in digital applications up to 40 Gb/s NRZ with excellent results. 

PDL-100A OEM

Incorporate 0 to 625.0 ps of delay range into your products with the trombone only version of our instrument. 

PDL-200A

For differential signal applications, this unit offers dual PDL-100A trombones side-by-side in one unit.  

Customized for total range and smallest step size.

There are times when precision to 0.50 ps is not required and therefore a trombone is not necessary. With Aerospace grade microwave relays and precision-cut semi-rigid coaxial cable, we can achieve the smallest step size of 10.0 ps. Both the entire range (up to 200.00 ns) and step size (no smaller than 10.0 ps) of the CPDL can be custom or specified by the customer, hence Custom Programmable Delay Line Instrument.

 

CPDL-100A→

Both the entire range (up to 200.00 ns) and step size (no smaller than 10.0 ps) of the CPDL can be custom or specified by the customer.

CPDL-200A→

Highest performance precision with extended range in a custom dual channel unit.

Utilizing PIN diode switching technology.

PDM-100A→

The key hallmark of this series is all solid-state-electronics offer much faster switching speed and in modular form (modules). Using PIN diode technology, the PDM-100A instrument offers 0 to 5.12 ns of total delay with a step resolution to 1 ps.
