• Delay line method measurements

DESCRIPTION

The DL-2 is a delay line unit that may contain up to

two line stretchers each providing 250 ps of time delay. The

line stretchers have independent inputs and outputs so that

they may be used separately or daisy-chained to provide up

to 500 ps of delay. Each line stretcher is motorized and can

be used for continuous delay adjustment. 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.
