DESCRIPTION

The DL-1 is a delay line unit that can be used to insert up to

128 ns of time delay. Calibrated transmission lines are

switched in and out to adjust the delay from input to output.

An adjustable and motorized line stretcher is used for

continuous delay adjustment with a range of 0 to 500 ps. The

unit has an additional input port that bypasses the long

coaxial delay sections for better VSWR performance at high

frequencies where long delays are not needed. All delay line

unit functions are accessible from the front panel. The unit is

also supplied with a RS-232 interface for remote control and

automation. This unit can operate as a stand-alone unit or

may be used with the NMS series of measurement modules.
