What is a programmable delay line?


A programmable delay line allows a user to programmatically specify and modify delay in a high frequency/RF signal path. This results in a signal delay, as measured in the time domain, or a phase shift, as measured in the frequency domain.


How is delay achieved?

Precision delay is introduced into the high frequency signal path (or transmission line) by the expansion or compression of the patented electromechanical trombone.


Coarse delay is offered through a switched network of Aerospace grade microwave relays and precision cut low-loss semi-rigid coaxial  cable. Total delay is the sum of each switched relay section of delay.
